肇論 義疏通講

Before reading the four treatises, why does Huida first write a preface?

Begin with the textual ground: first discern whose voice this is

When the Zhaolun opens, the first voice is not Sengzhao's. It is that of Huida, Śramaṇa of the Small Zhaoti Monastery. His first sentence says that he is writing a general preface to the Fundamental Thesis and the four treatises beginning with On the Immutability of Things, works composed by Dharma Master Sengzhao of Chang'an. That sentence protects a basic distinction for the reader: the sequence of the four treatises, the lineage of Kumārajīva's community, the Six Houses and Seven Schools, and Kumārajīva's praise are presented in Huida's guide to Sengzhao after he had read the treatises. They must not be rewritten as Sengzhao's own preface.

Although the preface does not transcribe a passage from a prajñā sūtra line by line, it makes its scriptural and treatise coordinates clear. Huida moves from the contemplative methods of the Middle Treatise, the Hundred Treatise, and the Twelve-Gate Treatise to the profound Mahāyāna sūtras. He then calls prajñā the cause of complete and perfect realization and nirvāṇa the ultimate fruit. This is not the creation of a fifth treatise. It tells the reader that the four treatises are to unfold within a Mahāyāna and prajñā path of reading.

Why does Huida write a general preface before a particular preface?

Xiaoyue catches the structure of the entire work by dividing the preface into two chapters: the first explains the occasion from which the treatises arose and is the general preface; the second properly explains the guiding intent of the treatises and is the particular preface. What looks at first like an elaborate foreword thus becomes two live questions: Where did these treatises come from? And in what order should a reader enter them?

The general preface answers the first question. Huida first places the responsibility for transmitting the sūtras in the latter age upon those who protect the Dharma according to the teaching. He then moves from Dao'an and Kumārajīva to Sengrui, Xie Lingyun, and the monastic and lay community, evoking a world of translation and teaching in which languages were corrected, textual meanings ordered, established terminology examined, and doctrine closely investigated. Sengzhao did not compose in a void outside that world. He matured within Kumārajīva's shared work of translation and scriptural inquiry, while answering it in a voice distinctively his own.

The particular preface answers the second question. Huida no longer recounts people and an age, but arranges the four treatises into a path: the Fundamental Thesis first marks out true reality; the two truths, ultimate and conventional, open the gate of empty dharmas; prajñā is the cause; nirvāṇa is the fruit. Only when a sequence is given will the reader not break the four pieces into unrelated sayings. Yet as soon as he establishes the sequence, Huida relinquishes the characteristics he has established. He does not permit the reader to grasp the root or the two truths as newly fixed names.

Among the thousands around Kumārajīva, why is Sengzhao singled out?

Huida's mention of more than three thousand monks and some eight hundred lay followers is not an attempt to overwhelm the reader with numbers. It shows that the age already possessed a vast community of translation, teaching, and treatise composition. Only then does he bring Sengzhao forward as the worthy man who surpassed speech while according with silence, who marked the root sentence by sentence in penetration of the Buddha's mind, and who clarified the branches sentence by sentence throughout the teachings.

"Marking the root" and "clarifying the branches" form a blade for reading the preface. If one speaks only of the root, the words may hang too high; if one speaks only of the branches, the guiding intent may scatter. Huida prizes Sengzhao because he can mark out the fundamental thesis while allowing each sentence of the treatises to reach concrete teachings. Xiaoyue therefore reads the Fundamental Thesis as an overarching statement of the guiding intent of the four treatises, and the four pieces beginning with On the Immutability of Things as clarifying principle through matters and guiding later students. The "combination" praised in the preface is not a blending of schools into one mass. It is root and branches illuminating each other, speech and silence supporting each other.

Why should the Six Houses and Seven Schools be recorded here, but not adjudicated?

Huida looks back upon the Six Houses and Seven Schools and the extension to twelve, explicitly noting their judgments of good and faulty, deviation and fitness. This is a discerning review of earlier teachings. Yet this unit is not On the Emptiness of the Unreal itself and cannot decide the doctrinal merits of every school in advance. Here the reader need see only this: Huida places the Zhaolun within the history of competing early prajñā interpretations and expresses his own orientation by declaring Sengzhao's work alone sufficient to serve as a standard.

The marketplace report recorded in the preface must likewise be read according to its literary role. Some claimed that Sengzhao's writings were merely the ultimate-truth teaching of the Chengshi Lun, the comprehensive doctrine of the Treatise on the Ten Stages, and language borrowed from the Zhuangzi and Laozi. These are the jeers Huida rejects, not a hidden genealogy that the preface concedes. To turn a rejected claim into Huida's own position would invert the whole general preface.

After more than twenty years in teaching halls, why does Huida still say that he saw these treatises only at the end?

Huida was not a beginner who happened upon a book. He says that he had spent more than twenty years in teaching halls and met many distinguished seats, yet only at the end encountered these treatises. His joy is therefore not the excitement of novelty, but the joy of meeting a "right sound" after a long search for the Dharma.

That joy explains the preface's intensity: reading without weariness, moving hands and feet with delight, vowing to transmit the treatises life after life, even vowing not to meet those who followed the jeers. An exposition need not cool this language down. It shows that Huida is not compiling a detached catalogue, but protecting a work that he encountered fully only after many years. Even so, he leaves examination to those who come later, asking like-minded worthies to await sages of the future. Fervent protection of the treatises and an invitation to later examination stand together in the preface.

How does the sequence of the four treatises become a path of reading?

Huida begins by saying that, in the broad division, the profound meaning is called fundamental non-being, and that the guiding thesis is therefore established in words to mark out true reality. This is the entrance. The Fundamental Thesis first marks the guiding intent of the whole collection. On the Immutability of Things and On the Emptiness of the Unreal then open ultimate and conventional truth; On Prajñā Without Knowing presents the cause of complete realization; On Nirvāṇa Being Nameless presents the ultimate fruit.

Yet an entrance must not become a cage. Huida immediately says that although emptiness of intrinsic nature is used to point toward the root, there is no root that can be named, and that to speak of the root is already beyond speech, not a place reached by the activity of thought. Fundamental non-being is only a guiding name. To seize it as a nameable and thinkable entity would contradict Huida's own insistence that no root can be named. Xiaoyue sharpens the point: when the mouth would speak, its words are lost; when the mind would take the matter as an object, its thought is forgotten. The point is not that there are no words or no mind, but that neither speech nor discrimination can enclose the principle toward which they point.

Thus On the Immutability of Things concerns the conventional, yet conventional dharmas are unborn; On the Emptiness of the Unreal concerns the ultimate, yet the ultimate is spoken only through names. Prajñā is said to be without knowing, and nirvāṇa to be nameless. The four treatises establish a path of reading while gradually loosening the reader's grasp upon the names established along that path. This is what the preface means by prose linked like interlocking rings: each sentence receives the one before it, while also preventing the one before it from hardening.

How should Kumārajīva's praise be read?

Huida closes his praise with an exceptionally high assessment attributed to Kumārajīva: Master Zhao is foremost in understanding emptiness. The preface preserves this evaluation and Huida uses it to establish the weight of the Zhaolun. The extant monastic biography can verify Kumārajīva's remark that his own understanding was not inferior to Sengzhao's but that he should receive from Sengzhao in matters of expression. It does not, however, yield the same continuous wording as the statement preserved in the preface. The reader may therefore know with confidence that this praise is transmitted in Huida's preface and Xiaoyue's commentary without being compelled to assign it an earlier documentary source that has not been established.

Such honesty does not weaken the preface. It allows two voices to remain in their proper places: Huida preserves the praise of Kumārajīva as he knew it, while the present edition preserves the boundary of what the extant canon can demonstrate. Transmission hands on what is certain and what remains uncertain together; it does not fill every gap with certainty.

Continuation / what carries forward

What first carries forward from the Preface to the Zhaolun is a way of reading. Xiaoyue's division into six sections of the general preface and four divisions of the particular preface lets later readers see Huida's order of operations: he first explains the people and the transmission, then the doctrine and its sequence; he first protects the Zhaolun, then warns against grasping the names it establishes. The Jin commentary attributed to Huida supplies a parallel allocation in which the two truths illuminate the first two treatises, while prajñā and nirvāṇa illuminate the latter two, but it does not gloss this preface line by line. When each ancient commentary remains within the scope it actually possesses, no one mirror covers over Huida's original preface.

After this preface, as the reader enters the Fundamental Thesis and the four treatises, the most important thing is not to memorize a set of labels in advance. It is to remember the movement Huida arranges: enter through transmission and read according to the sequence; establish the root so as to know the direction, then relinquish the root so as not to become stuck; open the gate through the two truths, then pass by prajñā to nirvāṇa. The preface does not speak on Sengzhao's behalf. It opens the door through which later readers may approach him.

The Scriptural Question First: Can Being and Non-being Each Stand Fixed?

All dharmas plainly appear. Why, then, call them empty of intrinsic nature and speak of fundamental non-being? If emptiness meant that everything before us had been annihilated, dependent conditions and the results of action could no longer be established. Yet if appearance meant that things possessed an unchanging intrinsic entity, their ceasing when conditions disperse could not be explained. The Vimalakīrtinirdeśa-sūtra opens both sides at once: the Dharma taught is neither being nor non-being, for dharmas arise because of causes and conditions. Being is not a fixed being, and non-being is not an annihilating non-being. Precisely because dharmas depend on conditions to arise, they cannot be fixed on either side.

The Fundamental Thesis therefore begins with five names: fundamental non-being, true reality, dharma-nature, intrinsic-nature-emptiness, and the coming-together of conditions are one meaning. The question is not how to arrange five items in a glossary, but how to follow Sengzhao's reasoning and see that all five names point to the same fact.

Why Is Fundamental Non-being Named First but the Explanation Begins with Conditions?

The list places fundamental non-being first, but the argument begins from the coming-together of conditions. The most readily visible fact is that things arise when conditions gather and cease when conditions disperse. If a dharma truly possessed a fixed intrinsic entity, it should not cease when conditions disperse. Since it does cease, we can know that although it presently appears, its nature has always been empty.

Yuankang points out that the text first lists fundamental non-being, then begins its joined explanation of the five meanings with the coming-together of conditions because this follows what is readily accessible. The path of reading therefore moves in reverse: from the coming-together of conditions to being empty of intrinsic nature; from intrinsic-nature-emptiness to dharma-nature; from dharma-nature being just so to true reality; and from true reality being fundamentally non-being to the name fundamental non-being. The five names are not five separate realms. They name different joints along a single fact.

Fundamental non-being is the term most easily misread. It does not mean that something once truly existed and was later contemplated as empty, refuted, and finally turned into nothing. The treatise says that true reality is of itself non-being; it is not made non-being through inferential elimination, and therefore it is called fundamental non-being. Yuankang follows by saying that dharmas are of themselves non-being and this is called true reality; they are not made non-being by being conceptually dismissed. Fundamental non-being thus says that true reality is fundamentally so. It does not describe a mind canceling the world.

Is Neither Being nor Non-being a Compromise Between Two Sides?

If neither being nor non-being merely shaved half away from being and half away from non-being, it would not yet touch the grasping Sengzhao seeks to remove. The treatise first identifies both sides precisely. "Not being" does not deny the conditioned appearance before us; it denies the determinate being posited by views of existence and permanence. "Not non-being" does not deny emptiness; it denies the determinate non-being posited by wrong views and annihilationism. What is dispelled is fixed being and fixed non-being, not dependent appearance or intrinsic-nature-emptiness.

This is why Sengzhao next says that one who contemplates dharmas without retaining non-being may be said to know the true reality of dharmas. If the mind first stores away an annihilating non-being, emptiness itself becomes another thing to grasp. At the same time, although one contemplates being, one does not grasp a fixed characteristic. Yuankang joins these two sides: contemplating dharmas without retaining non-being means that non-being is not non-being; contemplating being without grasping a characteristic means that being is not being. Abiding in neither being nor non-being is the practice of abiding without anywhere fixed in which to abide.

If the Three Vehicles Contemplate the Same Thing, Where Does Their Difference Lie?

The treatise says that the three vehicles equally contemplate intrinsic-nature-emptiness and thereby attain the path. If each vehicle contemplated a different intrinsic-nature-emptiness, the chapter's fundamental claim that the five names share one meaning would already split apart. Yet if the three vehicles did not differ at all, why would there be three vehicles? Sengzhao's answer is restrained: the dharma contemplated does not differ, but the contemplating mind differs in measure.

Seeing the true reality of all dharmas is therefore right contemplation; seeing something contrary to this is wrong contemplation. Yuankang explains the remaining difference as one of greater or smaller mind and deeper or shallower wisdom. Shared contemplation does not erase differences among practitioners, while differences among practitioners do not divide true reality into different objects.

How Can One Contemplate Emptiness Without Taking Realization and Engage with Being Without Being Stained?

If one contemplates emptiness and immediately takes realization as a possessed fruit, one cannot go forth to teach and transform beings. If one engages with being while losing emptiness, one becomes stained by sensory defilements. The Fundamental Thesis answers this tension through the two gates of prajñā and skillful means. Prajñā contemplates the true reality of all dharmas, so one engages with being without being stained. Skillful means goes forth to transform beings, so one contemplates emptiness without immediately taking realization as a possessed fruit.

Sengzhao's own formulation is clearest: engaging with being never loses emptiness, so one constantly dwells amid being without being stained; not growing weary of being while contemplating emptiness, one contemplates emptiness without taking realization. Engaging with being without losing emptiness means true insight is present within skillful means. Contemplating emptiness without growing weary of being means skillful means is present within true insight. These are not two moments alternating in sequence. They are skillful means and wisdom present together in the power of a single thought. Yuankang therefore says that prajñā and skillful means mutually include one another. If either gate obscures the other, great wisdom cannot appear in full.

When the Bonds Are Exhausted, Is There Another Place Called Nirvāṇa?

The final gate closes with striking brevity: when the afflictive bonds are exhausted, birth-and-death ceases forever, and this is called the truth of the exhaustion that is nirvāṇa. The mind may still ask where one goes after the bonds are exhausted. Sengzhao does not allow that question to manufacture another place: there is no separate place of exhaustion.

Yuankang's blade is briefer still: exhaustion exhausts the bonds; once the bonds are exhausted, there is no separate exhaustion. Exhaustion describes affliction as exhausted. It does not establish somewhere outside birth-and-death called "exhaustion." Looking back across the chapter, the coming-together of conditions does not establish determinate being, and intrinsic-nature-emptiness does not establish annihilating non-being. Prajñā does not become stranded in emptiness, and skillful means does not become stained by being. Nirvāṇa too is not solidified into another place in which to abide. All four gates prevent the mind from freezing an expedient expression into something graspable.

Continuation / What Carries Forward

Yuankang classifies the Fundamental Thesis as the statement of the thesis and the four treatises from Immutability onward as the elucidation of the teaching. This continuation does not replace Sengzhao with a later commentary. It points out the four paths already laid within the short chapter: fundamental non-being and true reality unfold as On the Immutability of Things; neither being nor non-being unfolds as On the Emptiness of the Unreal; skillful means and prajñā unfold as On Prajñā Without Knowing; and the truth of the exhaustion that is nirvāṇa unfolds as On Nirvāṇa Being Nameless.

The Fundamental Thesis should therefore be read neither as a list of five terms nor as a summary of the four later treatises. What it establishes is a way of reading: see intrinsic-nature-emptiness within the appearance of conditions coming together, yet do not turn emptiness into annihilating non-being; contemplate emptiness while continuing to engage with being, and engage with being without losing prajñā; speak of the exhaustion of the bonds without creating a separate place of exhaustion. Each of the four treatises will extend its own line, but none departs from the doctrinal backbone established here.

The scriptural question first: Where are neither coming nor going to be seen?

The wind blows, rivers rush, the sun and moon travel, and a person passes from youth into white-haired age. Everything before our eyes is changing. Why, then, does “On the Immutability of Things” insist that things do not shift? If immutability means that nothing happens, then the whirlwind, the torrent, birth and death, cold and heat all become empty words. Yet if we admit only flux, how are we to read the Fangguang scripture’s statement that dharmas have neither going nor coming and undergo no movement or turning?

Sengzhao does not ask us to close our eyes and deny motion. He first places before us two pieces of evidence from Prajñāpāramitā and Madhyamaka. The Daoxing says that dharmas originally have no place from which they come and, in going, have no place they reach. The Madhyamaka sentence says that, by observing a direction, one knows that someone is going, yet the one going does not reach a direction. The question therefore changes. It is no longer only, “Did it move?” It becomes, “What fixed ‘it’ is there that moved from here to there?”

Yuankang brings the issue to a sharp point: there is no single thing fixedly abiding that migrates from here toward there; this is why it is called immutable. Immutability is not the absence of difference between before and after. Precisely because before and after already differ, no fixed and unchanging identity can be found that has been transported from the earlier moment into the later one. If this boundary is kept clear, the treatise will be read neither as permanence nor as annihilation.

How can the same fact—“the past thing does not reach the present”—look like motion to one person and stillness to another?

Ordinary people see that yesterday’s thing is not here today and say, “It moved; it went away.” Sengzhao begins from the very same fact—that yesterday’s thing did not come into today—but asks in return: since it did not reach today, why not say that it remains only in yesterday and never left its own temporal position?

Ordinary people and Sengzhao therefore do not face two different sets of facts. Their angles of view are opposed. Looking at the present absence of the past thing, ordinary people see going. Looking at the past presence of the past thing, Sengzhao sees abiding. Search in yesterday for yesterday’s thing, and it was never absent. Ask for yesterday’s thing today, and it has never existed here. This does not preserve yesterday as an eternal entity. It refuses to imagine that a thing of yesterday crossed through time and moved as a whole into today.

Reverse the direction and the same holds: today’s thing has not returned into yesterday. The ancient does not reach the present, and the present does not reach the ancient. A past thing is of itself in the past; a present thing is of itself in the present. Yuankang’s teaching that stillness is sought within moving dharmas, that the very moving is the still, comes to rest precisely here. Stillness is not found by escaping from motion. It is found by seeing that, throughout change, no fixed thing travels back and forth between two temporal positions.

Whirlwind, rivers, mirage, sun and moon: The faster the motion, the less one can find who migrates

The treatise’s most brilliant four lines are not ornament. They press the argument to its limit: the whirlwind fells the mountains, and yet is ever still; the rivers race in torrents, and yet do not flow; the mirage drifts and surges, and yet does not move; the sun and moon traverse the heavens, and yet do not complete their circuit.

The whirlwind can fell a high mountain. Could motion be more forceful? Yet the earlier wind is not the later wind, and no fixed wind can be found migrating from one position to another. Rivers race without pause, yet the earlier water is not the later water; one cannot imagine an identical drop as an unchanging entity running through the entire river. The mirage is a vapor that appears to surge in sunlight, yet the earlier haze is not the later haze. The sun and moon traverse the heavens, yet the earlier sun is not the later sun. The four images do not abolish the appearances of wind, water, haze, or the sun and moon. What they force us to relinquish is the “mover” tacitly assumed to remain identical while being transported from here to there.

The faster the motion, then, the sharper the question of immutability becomes. The eye sees only a continuous movement, and the mind supplies it with one identical thing. The author instead asks within that continuity: if the former is already not the latter, who crossed from before into after? This question does not freeze the world. It loosens our fixation on “the identical thing.”

Do impermanence and immutability contradict one another?

The author himself raises the strongest objection. The noble teaching says plainly that human life passes faster than a river’s current. Śrāvakas realize the path by awakening to impermanence; pratyekabuddhas enter the real by awakening to the dispersal of conditions. If none of the myriad movements were transformation and passage, how could anyone realize the path through the principle of impermanence?

The answer is not a choice between two alternatives. From the side of moment-by-moment alteration, the teaching speaks of “going.” From the side of each temporal position, across which no fixed thing passes, the author speaks of “abiding.” Yuankang fastens the two together: taking moment-by-moment alteration, one speaks of going; taking each as abiding in one time, one speaks of abiding. Abiding is just such a going, and going is just such an abiding. Immutability therefore does not overturn impermanence. It refuses only to describe impermanence as one permanent entity changing addresses in time. Impermanence discloses difference between before and after; immutability discloses that no fixed thing passes from the former to the latter.

This also explains why the teaching sometimes speaks of going and sometimes of abiding. When beings cling to permanence, the noble teaching speaks of going so that they no longer suppose one thing to keep the same form forever. When beings cling to annihilation, the noble teaching speaks of abiding so that they do not understand causal efficacy as an utterly broken succession. Yuankang puts it directly: going is taught for the sake of conditions, yet in truth it is not going; abiding is taught for the sake of conditions, yet in truth it too is not abiding. Each teaching treats one extreme. Neither side can be grasped as a final entity.

The white-haired brahmin: I still resemble the person of the past, yet I am not that person

A brahmin leaves home while young and returns only after his hair has turned white. A neighbor asks whether the person from long ago is still here. He replies that he resembles that former person yet is not that former person. The answer sounds contradictory, but it illuminates two sides of ordinary experience. If he were wholly other, how could the neighbor recognize him at once? If he were wholly the same, where did the form of the youth go?

Ordinary people say that the person from youth to maturity has one body. They notice that the years have gone but not that the form too has gone with each span of years. Sengzhao does not cut succession in two and declare before and after entirely unrelated. He points out that succession cannot in turn prove one identical substance unchanged over a hundred years. “Resembling the former person” speaks to recognizable continuity; “not the former person” speaks to difference between before and after. The two stand together, just as motion and stillness, going and abiding, stand together.

If the cause does not come into the present, how can the fruit still arise from it?

At the end another question appears. If a former cause remains only in its former time and does not migrate into the present, how can the present fruit be established? Does saying that the former cause does not come sever cause and fruit?

The author answers with building a mountain and completing a journey. A mountain takes shape as the first basket of earth is followed by further baskets. A long road is completed as the first step is followed by further steps. The first basket is not moved into the last basket, and the first step does not migrate into the final step. Yet the earlier effort does not therefore perish, and the later effort continues precisely through what preceded it. Because fruit is not simultaneous with cause, the cause does not come into the present. Because fruit arises in dependence on cause, the cause does not perish in the past. “Not coming” prevents us from transporting the cause into the fruit; “not perishing” prevents us from severing cause and fruit.

Immutability thus becomes more than a paradox about time. It becomes a way to understand causality: do not treat the earlier cause as a thing moved into the later fruit, and do not reduce the efficacy of the earlier cause to nothing. The effort remains in the past without being transformed into the present, while the fruit in the present comes to be through that cause. Cause and fruit are not simultaneous, yet their succession is not broken.

Continuation / what carries forward

“On the Immutability of Things” was already catalogued as an independent work in the Southern Dynasties Fā lùn mùlù. In the Tang dynasty, Yuankang divided it into the preface’s four passages and the main treatise’s six sections, preserving for later readers a passage-by-passage road through the text. What matters most in this continuation is not a new system laid over the treatise. It is the sharpening of the author’s own question: because the world plainly changes, must we therefore assume that a fixed thing is migrating?

Look again from here at the whirlwind, the rivers, the mirage, and the sun and moon. None of their motion has been diminished. What has been loosened is only the fixed thing imagined to move from an earlier position into a later one. If this can be seen in the very things before us, there is no need to escape the torrent in search of stillness elsewhere, and no need to deny the torrent because stillness is taught. Only then does our confusion about motion and stillness truly return to the things immediately at hand.

The scriptural question first: Does emptiness turn everything before us into nothing?

The desk is before you, sounds enter your ears, and the body is now feeling heat and cold. If all dharmas are empty, must these first be excluded—must one wait until nothing can be seen or heard—before reaching ultimate truth? If not, then the myriad things before us plainly appear. From where, exactly, is their emptiness spoken?

“On the Emptiness of the Unreal” places the question between being and non-being. The Mahāyāna Treatise says that dharmas have neither the characteristic of being nor the characteristic of non-being. The Madhyamaka sentence says that dharmas are neither being nor non-being, and that this is ultimate truth. This does not stir being and non-being together into a vague third thing. It first refuses two fixed views: because the myriad things appear, they must not be grasped as truly existent; because they lack intrinsic nature, they must not be driven into total absence.

At the outset, Yuankang reminds us that this treatise clarifies that dharmas are unreal and are therefore not truly existent; precisely because they are unreal, they are empty. Emptiness is not a “non-being” established beside “being,” nor is it the result left after being has been annihilated. To read emptiness as annihilation is to fall into the very extreme view the treatise seeks to break.

First consider the three schools: The problem lies neither only in the mind nor only in the word “non-being”

Why does Sengzhao begin with No-mind, Matter-as-such, and Fundamental-Non-being? Because when emptiness takes hold of only one side, it moves farther and farther from the things before us.

The No-mind teaching emphasizes not raising an attached mind toward the myriad things, while it still holds that the things themselves have never been absent. Sengzhao acknowledges that it can quiet the spirit, yet points out that it has not seen the unreality of the things themselves. Yuankang puts the gain and loss clearly: because it remains without attachment toward dharmas, it is a gain; because it does not know that the nature of things is empty, it is a loss. If emptiness means only “my mind does not cling,” then things are still preserved as fixedly real. Emptiness treats only the mind and has not illumined the dharmas.

The Matter-as-such teaching sees that form cannot make itself into form and must depend on conditions. It therefore says that form, though appearing, is not fixed form. But the treatise asks: once one knows that form does not make itself form, has one already seen that form is not truly form? Yuankang says its shortcoming is that it does not know that form is fundamentally empty and still preserves provisional being. This does not deny conditional constitution. It presses it one step further: precisely because form waits upon conditions, it has no independent and unchanging real body.

The Fundamental-Non-being teaching, meanwhile, readily draws every sentence toward non-being. It reads “not being” as eliminating being and “not non-being” as eliminating even non-being. Sengzhao asks why “not being” must mean making this being absent, and “not non-being” must mean making that non-being absent. The scripture’s intent is simply that being is not true being and non-being is not true non-being. A one-sided love of non-being does not follow facts to comprehend them and does not see their true condition in the things themselves.

The treatise gives clear judgments on all three schools. This exposition unfolds only the treatise author’s own questions and answers; it does not rank the schools anew from outside the treatise. What matters is to see where the three missteps occur. Merely quieting the mind, merely seeing that form does not form itself, or merely drawing scriptural language toward non-being has not yet fully reached appearance that is present without being truly existent.

No need to cut apart the myriad things: Emptiness is present while form appears

The treatise next presents a misreading that is easy to recognize. Must one wash away the myriad things, block sight and hearing, and enter vacant desolation before reaching ultimate truth? If emptiness can be established only after things disappear, then it becomes another state that follows their destruction. Being and emptiness would remain two opposed things arranged before and after.

The scripture says that the nature of form is empty and that form does not become empty only when it is destroyed. While form appears, it already stands through manifold conditions and possesses no body of its own apart from them. There is not first a solid, real form that must later be smashed before emptiness can emerge from the pieces. Yuankang’s sharp sentence cuts off the misunderstanding: form itself is empty; it need not first be cut apart and destroyed before emptiness is reached.

A mirror-image can help make this clear. When a person stands before a mirror, an image appears distinctly; one cannot say that no image appears. Yet apart from the face, the mirror, the light, and the distance between them, no independently existing mirror-image can be found. The image does not become empty only when the mirror breaks. While appearing, it has no fixed body of its own. This is precisely “although being, non-being”: it has appearance, yet lacks truly existent intrinsic nature.

Conversely, because the image does appear when conditions come together, one cannot say that it is wholly absent. This is “although non-being, being”: absent in intrinsic nature, present through conditional constitution. “Not being” does not erase appearance, and “not non-being” does not preserve a substantial entity. Together the two statements remain faithful to what stands before us without allowing it to be grasped as truly existent.

Conditions as the measure: True being would not wait for conditions; true non-being could never arise

How do we judge that something is not truly existent? Sengzhao does not tell us to rely on feeling alone. He tests it by conditions.

If a thing were fixed, real being, it should exist forever by itself from the outset. Why would it need to wait for conditions before arising? If a sprout appears only when seed, soil, water, and season are present, then the sprout is not true being established on its own apart from conditions. It arises, but its arising cannot be mistaken for existence by intrinsic nature.

Can we then say that the sprout is wholly absent? No. Fixed and genuine non-being would have to remain forever quiescent and could never arise when conditions became complete. Since the sprout does emerge through conditions, it is not annihilative non-being. Precisely because it waits upon conditions, it is not truly existent; precisely because it can arise, it is not wholly absent.

This is the treatise’s double reason: the myriad things have a reason for not being truly existent and a reason for not being wholly absent. To say only the first readily pushes emptiness into annihilation. To say only the second readily turns dependent arising into substantial existence. Only when the two hold together does the emptiness of the unreal become visible.

The illusory person: A human form appears, yet no real person can be found

The treatise’s clearest simile is the illusory person. Dharmas are provisionally designated and not real, like a person conjured by illusion. It is not that no illusory person appears, yet that illusory person is not a real person.

When the illusion is performed, a human form and movements can be seen, so one cannot say it is wholly absent. Yet when one asks where the real person is, none can be obtained. “It is not that no illusory person appears” blocks annihilation. “The illusory person is not a real person” blocks true existence. The two statements do not cancel one another; together they identify the status of appearance.

This also resolves the relation between “unreal” and “empty.” Unreal does not mean that phenomena have no operation at all. Empty does not add a layer of nothingness outside phenomena. Unreal means that what appears possesses no real body that can be fixed and grasped. Precisely for this reason, it is called empty. Yuankang’s summary is exact: because it is not truly existent, it is called unreal; because it is not truly existent, it is therefore called empty. The treatise receives its title from this reasoning.

A name is not a real thing: Why can “this” and “that” exchange places?

The argument now moves from conditions to names and realities. If a name were genuinely the real thing, saying “fire” should burn the mouth. If a real thing naturally carried one unique and unchanging name, then people looking at the same place from different directions should not call it “this” at one moment and “that” at another.

Yet a person on this side calls his own position “this” and the opposite side “that.” Once he stands opposite, “this” and “that” exchange places. Names help us indicate things in daily life, but they do not thereby become the things themselves. The treatise says that names do not correspond to realities, realities do not correspond to names, and when neither corresponds, where can the myriad things be fixed? This does not ask us to discard language. It asks us not to mistake an expediently established name for the fixed and unchanging body of a thing.

“Provisional designation” should be understood in the same way. “Provisional” means established in dependence on conditions, convention, and indication; it does not mean fictitious to the point of total absence. “Designation” is the name that lets people speak, distinguish, and understand one another; it is not the true body of the thing. Names can be used but not grasped. Appearances can be seen but not fixed. From both sides, name and reality return us to “unreal.”

True truth is not outside things: Encountering affairs and meeting the true

One final question remains. If names are not realities and the myriad things are unreal, is ultimate truth still hidden somewhere far from ordinary use?

The treatise answers in exactly the opposite way. The sage does not take a separate emptiness and use it to make the myriad things empty. He directly sees that they are empty of themselves and does not borrow emptiness in order to empty them. Emptiness is not a method he imposes on the world. The fact that the myriad things are conditioned, provisionally designated, and without intrinsic nature is how they already are. He passes through a thousand transformations without changing and walks among ten thousand confusions while remaining comprehending, not because he escapes transformation and confusion, but because he no longer fixes any dharma within them as truly existent.

The close therefore says that the place where dharmas are established does not depart from the true; that very place is the true. The Way is not elsewhere but is met in the affairs one touches. Yuankang states it without hesitation: in encountering any affair, all is the Way; there is no separate Way. Eating, walking, seeing form, and hearing sound need not first be removed. What must be loosened is the mind that fixes conditionally constituted things as truly existent and then mistakes emptiness for total absence.

Continuation / what carries forward

The Southern Dynasties Catalogue of Dharma Treatises already recorded “On the Emptiness of the Unreal” as an independent work beside the Prajñā writings of Zhi Daolin and others. In the Tang, Yuankang divided the whole into preface-three and main-six and carefully distinguished the positions of the three schools from Sengzhao’s criticisms of them. What this continuation preserves is not merely a string of school names. It preserves a reusable way of reading: first ask whether what appears before us is truly existent; then ask whether emptiness means total absence; finally test each answer through conditions, illusion, and names and realities.

After the test, the myriad things have not disappeared and sight and hearing have not been shut off. What remains is precisely a world that appears without being real and arises through conditions without being absent. When one can avoid both substantial existence and annihilative non-being in each particular thing, the emptiness of the unreal is no longer an abstract term in the distance. It is the true that can be seen in the very affair one now encounters.

The scriptural opening: does “without knowing” mean without illumination, or without grasping?

On Prajñā Without Knowing opens by placing side by side two scriptural statements that seem contrary. The Fangguang Prajñā Sūtra says that prajñā has no existent mark and no mark of arising or ceasing. The Daoxing Prajñā Sūtra says that prajñā has nothing it knows and nothing it sees. If prajñā is wisdom, why do the scriptures not say that it knows more and sees more clearly? Why do they begin instead with no mark, no knowing, and no seeing?

Sengzhao's answer does not reduce prajñā to darkness, nor does it make the sage insentient like wood or stone. His question is this: when something is illuminated, must it be seized as “something I know”? If knowing requires grasping a mark, then grasping this mark leaves other marks behind. But if illumination does not appropriate any mark, that non-grasping illumination is no longer limited by one mark. Hence the treatise's sharpest sentence: the sage's mind is without knowing, therefore there is nothing it does not know; a knowing that is not knowing—this is called all-knowing.

Yuankang calls this “knowing without grasping marks.” The entire treatise turns on that phrase. What “without” removes is grasping, not illumination. What “knowing” preserves is discernment, not possession. Keep this gate, and the nine exchanges that follow will not read as self-contradiction.

First hear where the treatise speaks from: a question born in the Xiaoyao translation hall

This treatise is not detached metaphysical conversation invented away from the work of translating scripture. Sengzhao first recalls Kumārajīva: entering the Great Vehicle while young, passing beyond words and images, traveling from the West to China. He then recalls Yao Xing bringing Kumārajīva into the passes and assembling more than five hundred learned monks at the Xiaoyao Monastery to settle the Vaipulya scriptures together. Sengzhao calls his own learning meager, yet says that he personally sat in this gathering and there heard the Dharma he had never heard before.

The preface does two things. First, it shows that the question of prajñā arises from translation and hearing the scriptures, not from speaking apart from them. Second, it admits from the outset that sacred wisdom is subtle, formless, and nameless, beyond the reach of words and images. Everything that follows is therefore language “recklessly entrusted” to what cannot be enclosed by language.

The reader must carry this self-limitation forward. “Knowing” is not a final entity, and “without knowing” is not a final entity. Both names are established to communicate sacred wisdom; neither may be turned back upon it to cut the sage's mind in two.

An empty mind is not a blank: the more complete the illumination, the less it establishes illumination as its achievement

Sengzhao begins with the sage's present functioning. The sage empties his mind and makes his illumination real; he knows all day and yet never establishes knowing. To empty the mind is not to appropriate the marks illumined. To make illumination real is to leave no subtlety among the myriad dharmas unseen. Precisely because he does not grasp marks, his radiance need not display itself. Precisely because it does not display itself, illumination remains unrestricted.

The treatise's language is exact: wisdom exhausts what is hidden without knowing; numinous response encounters things without deliberation. It illumines beyond phenomena but never leaves phenomena, and responds beyond the world but spends the whole day within the world. Yuankang therefore warns that “beyond phenomena” does not mean an emptiness existing elsewhere than form. If empty-mindedness is read as a blank, real illumination is lost. If real illumination alone is seized, illumination becomes a knowing one can possess.

Sacred wisdom is therefore real yet not existent, empty yet not nonexistent. To call it simply existent is to seek its form and name. To call it simply nonexistent is to make the sage's numinous response unintelligible. Emptiness does not lose illumination; illumination does not lose emptiness. They are not switches taking turns, but two aspects of the same sacred wisdom.

The first objection: if the sage truly knows and responds, why call him without knowing or encounter?

The first objector begins from the most direct experience. The sage illumines things one by one and omits nothing from knowing; he responds to the myriad matters without missing the occasion. Since there are things that can be known and encountered, and a capacity that knows and encounters them, how can knowing and encounter be denied? Even if the sage does not privately appropriate them, that would mean only that he does not own his knowing, not that he is without knowing.

Sengzhao first excludes the without-knowing of wood and stone. The sage's achievement surpasses heaven and earth, and his illumination surpasses the sun and moon. Without knowing cannot mean blindness. The real distinction is that ordinary knowing grasps marks, while the sage's illumination does not. If the sage first possessed a complete knowing that grasped marks and afterward modestly declined to call it “mine,” this would only be forgetting knowing; it would not mean that prajñā is itself without grasping.

Here Yuankang brings down the ancient commentator's blade: prajñā originally has no deluded knowing that grasps. It does not first seize a thing and then remind itself to release it. At the very first encounter it does not appropriate the thing as a fixed reality. This is why Sengzhao can say that knowing itself is without knowing; no second reflexive act is needed to turn it into something else.

Yet another question follows. If knowing were called pure merely because its nature is empty, would not every deluded knowing also have an empty nature? If prajñā were praised only because its object, ultimate truth, is pure, purity would belong only to the object and not to wisdom. Sengzhao therefore locates prajñā's purity in its originally lacking deluded grasping. Not every knowing is prajñā, and saying that knowing is empty does not by itself complete the distinction.

At the end, the image of elephant, horse, and rabbit crossing a river presses the answer to its limit. A rabbit or horse can enter the water and still fail to reach its deepest floor. When prajñā illumines ultimate truth, there is no depth left unexhausted, yet ultimate truth leaves no residual mark to be grasped. Complete illumination and non-grasping stand together: encounter without error, correspondence without fixing a “this”; still and without knowing, yet with nothing unknown.

The second objection: how can two names belong to one sage's mind?

The second objection turns to language. A name is not the thing itself, but it must correspond to something. Since knowing and without knowing are contrary names, if knowing fits the sage's mind, without knowing has nowhere to stand; if without knowing fits it, knowing has nowhere to stand. If neither fits, discourse has lost its purpose.

Sengzhao does not discard language. He limits it. Prajñā is nameless and unsayable, yet it cannot be communicated without words. “Knowing” is said to convey that illumination is truly present. “Without knowing” is said to distinguish its freedom from grasped marks. The former prevents prajñā from falling into annihilating non-being; the latter prevents it from becoming fixed being. The two names each block one extreme. They do not place two contrary substances inside the sage's mind.

Thus knowing itself is without knowing, and without knowing itself is knowing. This is not an arbitrary exchange of two words. The same illumination is named knowing with respect to its functioning, and without knowing with respect to its non-grasping. If names lead us to the sage's mind, we find two expressions within one illumination. If we cling to the names as mutually exclusive, we never reach what they indicate.

The third objection, part one: if ultimate truth is an object, must prajñā not possess knowing?

The third group of objections concerns object and wisdom. The first asks: ultimate truth cannot be fathomed without prajñā, and therefore ultimate truth is prajñā's object. If an object known exists, must there not be a knowing wisdom?

Sengzhao first distinguishes two relations between object and wisdom. Ordinary people establish an object's mark as what is known. Knower and known then arise by depending on one another, and what arises in mutual dependence is conditioned. Ultimate truth is called true precisely because it is not an object established by dependence on a knower and available for grasping. True wisdom illumines it without being generated by a marked object into grasping discrimination.

This is easily misheard as “true wisdom knows nothing.” Sengzhao says plainly that true wisdom is not insentient. It is not a knowing that grasps marks because ultimate truth is not a marked known. Not grasping does not mean not seeing. Precisely because it does not fix what is seen as a possessed known, true wisdom is not converted by one object's mark into ordinary discrimination.

The Madhyamaka statement about causes and conditions cuts here: if knower and known produce each other, they belong to conditioned dharmas, which have no intrinsic nature. Ultimate truth does not serve as a graspable condition, and true wisdom does not become a knowing produced by marks. To force a grasping knowing from the existence of an object has already changed ultimate truth into an object of conventional truth.

The third objection, part two: is there no grasping because there is no awareness, or does one know first and relinquish afterward?

The second question sets a dilemma. If non-grasping follows from a lack of awareness, the sage becomes a traveler at night who cannot distinguish black from white. If one first knows and later refrains from grasping, the moment of knowing still contains grasping, with release added only afterward.

Sengzhao accepts neither side. It is not because there is no awareness that there is no grasping, and it is not that knowing comes first and non-grasping second. Knowing itself is non-grasping; therefore it knows without grasping.

Non-grasping and illumination are not two successive steps. Divided into two steps, the first remains deluded grasping and the second only releases it after the fact. Prajñā, as this treatise speaks of it, does not turn the object's mark into its possession in the very act of knowing.

The third objection, part three: without a fixed “is” or correspondence, can the sage still respond appropriately?

The third question presses non-grasping into judgment. With no grasping, there is no fixed “this is so”; with no fixed “is,” there is no fixed correspondence. If nothing can be determined as what it is or made to correspond to the sage's mind, how can nothing remain unknown?

Sengzhao replies that precisely because the sage does not fix one thing in advance as the only possible correspondence, there is nothing to which he cannot respond as appropriate. Precisely because he does not fix one thing as the only possible “is,” there is nothing that cannot appear as what it is. No fixed correspondence means that every thing can be met in correspondence; no fixed “is” means that every thing can be seen as it is.

This does not abolish discernment. It abolishes preconception. Fix one “is” beforehand, and the myriad things are forced into one answer. Establish no correspondence in advance, and each thing can be met as it is. Sengzhao therefore speaks of seeing all dharmas and yet seeing no graspable seen, responding everywhere without setting up a fixed object of response.

The third objection, part four: why not take the signless as the final true mark?

The fourth question still seeks one last foothold. If knowing marked things is the illness, why not recognize the signless as the true mark? Sengzhao answers that this still has not escaped grasping. Yuankang points out that if signlessness is made a mark, signlessness itself has become another mark.

The treatise's image is severe: one flees a mountain peak and throws oneself into a deep valley. Grasping being is confinement on the peak; grasping non-being is falling into the valley. Rushing from one side to the other leaves the danger of both extremes untouched. Genuine non-grasping dwells in being without possessing being, and in non-being without possessing non-being. It neither grasps being and non-being nor abandons them.

The sage can therefore gather in his radiance, mingle with the dust, and move among the five destinies. He has not sought an unconditioned emptiness elsewhere than the conditioned world. Because he abides in neither being nor non-being, he can remain without contrivance amid the dust and yet leave nothing undone.

The fourth objection, part one: if response appears in season, does the sage's mind also arise and cease?

The final three questions turn to arising and ceasing. The first says: what can be answered is answered, and what cannot is held in reserve. If responsive manifestation begins and ends, must the sage's mind not sometimes arise and sometimes cease?

Sengzhao first distinguishes mind from response. Arising and ceasing belong to a grasping mind. The sage is without that mind, so the appearing and disappearing of responsive traces cannot establish that the sage's mind itself arises and ceases. Yet this does not make him entirely mindless or unresponsive. It is a mind without a grasping mind, a response that does not grasp response.

The image of the four seasons clarifies the point. Spring comes and plants grow; autumn arrives and leaves fall. The seasons never fail their appointed time. But one cannot infer from the coming and going of spring's appearances that the principle of the seasons is itself a thing suddenly born and suddenly destroyed. The sage's responses appear according to conditions just as the seasons arrive on time. Their substance is formless, so it cannot be seized as arising or ceasing.

The fourth objection, part two: how does prajñā without knowing differ from the empty nature of deluded knowing?

The second question is sharp. Prajñā is without knowing, yet deluded wisdom too is empty in nature; both may be said to have no fixed arising or ceasing. How can they be distinguished?

Sengzhao distinguishes being without knowing from knowing that knowing is empty. To be without knowing means that the sage's mind originally has no deluded grasping knowing; there is no knowing waiting to be removed. To know that knowing is empty begins with deluded wisdom already grasping marks and then says that this knowing is empty in nature. Yuankang states the distinction most clearly: prajñā does not grasp marks and therefore is called without knowing; deluded wisdom is empty in nature and therefore is called knowing emptiness.

The shared word “empty” cannot erase the difference between originally having no deluded grasping and already grasping before knowing that grasping to be empty. What is absent differs, so the two expressions cannot be merged.

The treatise then observes prajñā and ultimate truth through functioning and stillness. In functioning, inward prajñā illumines and outward ultimate truth is illumined; illumination's efficacy is not lost, so there is difference within sameness. In stillness, inner wisdom is without knowing and outer object is without marks; neither can be grasped, so there is sameness within difference. Fix them as the same, and illumination's efficacy disappears. Fix them as different, and wisdom and object each acquire an intrinsic nature. Their sameness must be discerned within difference, and their difference within sameness; neither sentence may be locked into an entity.

The wild duck and crane make this plain. One need not lengthen the duck's short legs or cut short the crane's long legs, level a mountain or fill a valley, before speaking of no difference. Their differing appearances remain, while their nature cannot be grasped. Prajñā and the dharmas likewise need not first be processed into one uniform shape in order to be equal.

The fourth objection, part three: are functioning and stillness two parts hidden inside prajñā?

The last question asks whether, if functioning differs while stillness is the same, prajñā contains one part called functioning and another called stillness.

Sengzhao gathers the entire treatise into one answer: functioning itself is stillness, stillness itself is functioning; they are one in substance, issuing together under different names. Stillness is not an empty husk left when functioning has stopped, nor is functioning a busy activity that departs from stillness. To posit a nonfunctioning stillness as the master behind functioning would be to create another pair of subject and servant inside the sage's mind.

The less wisdom displays itself, the brighter its illumination. The stiller the numinous, the more alive its response. Bright and obscure, moving and still, indicate the same sacred wisdom from different directions: when illuminating, it does not grasp, and so illumination itself is still; being still, it is not cut off, and so stillness itself illumines. The treatise has returned to its opening point. Without knowing is not the opposite of illumination. It is illumination without grasping marks.

Continuation / what carries forward

On Prajñā Without Knowing was born in the Xiaoyao translation hall. After Sengzhao presented it to Kumārajīva, his teacher approved both its understanding and its words. Liu Yimin later read it and sent a letter of inquiry, to which Sengzhao replied point by point. The treatise itself already contains nine exchanges; the appended correspondence presses further into questions of the sage's mind, concentration and wisdom, stillness and functioning. In the Tang, Yuankang's three chapters, five divisions, and four objections in nine exchanges preserved for later readers a path through the argument that does not lose its momentum.

What most matters in this continuation is not turning “without knowing” into a new technical object. It is preserving Sengzhao's question: must illumination grasp a mark? If it does not grasp, does illumination disappear? His answer refuses both sides throughout. The sage is neither insentient like wood or stone nor possessed of a knowing that grasps marks; he neither abandons being for non-being nor seeks stillness apart from functioning. Only when one sees non-grasping in the very act of knowing, and illumination within non-grasping, does “prajñā without knowing” cease to be a verbal contradiction and become a way of reading that does not turn sacred wisdom into a thing.

If the Sage's Mind Is Without Knowing, How Can It Still Respond to Beings and Transform the World?

Liu Yimin begins by drawing a line from the Treatise on Prajñā Without Knowing: without moving from equal awakening, the sage establishes all dharmas. This brings the living question of the entire letter directly before us. If there is truly no movement, how can all dharmas still be established? If there is illumination, response, and teaching, why call prajñā “without knowing”?

This is not a polemic against the treatise. After reading it, Liu says that it bathes the mind in the depths of the Mahāyāna vaipulya teachings and awakens the heart where darkness has been cut off. The greater his joy, the less willing he is to leave what he has not understood blurred over. He knows that when principle is subtle, words grow steep, and when a voice stands alone, few can answer it. Precisely because the treatise's purport is subtle and its words difficult, he sets out the questions that remain and asks Sengzhao to answer them clearly.

A Letter That First Draws Distant People Near, Then Brings Their Questions Together

The letter begins by asking about cold weather and illness. Messages cannot easily pass between north and south; rivers and mountains lie between Liu Yimin and Sengzhao, who have never met face to face. Yet Liu says that when understanding meets, people can draw near. He takes the treatise as an image and trace by which to reflect upon his own mind, and he gazes toward the clouds and sighs. These are not courtesies unrelated to the doctrine. They show what kind of relationship gives rise to the challenge: Liu does not seek victory, but understanding born of respect.

Yuankang divides the complete exchange into three parts—the treatise, the inquiry, and the reply—and the letter itself into the greeting, the questions proper, and the conclusion. Read in that order, the praise in the first half and the three questions in the second are not separate matters. Liu first acknowledges the treatise's power to cleanse the mind, then asks about the points it is hardest to convey: how stillness and knowing, the signless and responsive transformation, and the absence of fixed rightness together with true rightness can avoid undoing one another.

The General Inquiry: If Stillness and Knowing Are Not Two Things, How Is That to Be Explained?

Liu does not immediately divide his challenge into three questions. He first gathers together the treatise's functioning and stillness, quiet and response, and says that in the sage's mind knowing does not abolish stillness and stillness does not abolish knowing. The sage does not first leave the world for a stillness devoid of all function and then return to act. Nor does he lose profound stillness whenever he responds to things.

Yet setting these two statements side by side does not itself solve the difficulty. Since the sage's mind moves things, brings works to completion, and teaches in the world, it clearly illuminates and responds. Since it is said to be profoundly still and in accord with non-being, it cannot be treated as ordinary knowing that grasps and discriminates. Liu's real question is this: how does a knowing that does not abolish stillness differ from ordinary knowing? And how is a stillness that does not abolish knowing anything other than the insensibility of wood and stone?

First Question: Is It a Knowing That Exhausts Everything, or a Stillness That Responds Alone?

The first question raises two alternatives. Does the sage's mind exhaust numinous illumination and every mental function, subtly reaching their limit and darkly according with principle? Or is the mind's substance naturally numinous and still, responding on its own? If it exhausts all illumination and mental functions and thereby accords with dharma-nature, then stillness and illumination seem to remain the activities of meditative concentration and wisdom and can still be called a kind of knowing. If the mind's substance is merely naturally still and responds alone, its engagement with the many conditions appears almost to cease.

Yuankang places the edge of the question very plainly: does the substance of wisdom know, or is it without knowing? Neither side can be accepted carelessly. If one speaks only of knowing, “without knowing” becomes an empty name. If one speaks only of being without knowing, illumination and response have no way to stand. Liu does not answer in Sengzhao's place. He says only that there must be a deeper demonstration and asks him to make the distinction.

Second Question: If It Illuminates Only the Signless, Who Is There to Be Guided?

The second question moves from the substance of wisdom to the object it illuminates. Does the sage illuminate only the signless, or does he also see every change? If he sees beings and the changes of all things, what he sees appears to have marks. If he illuminates only the signless, there seems to be no one to guide and no condition with which to accord.

The treatise says that the sage's mind is originally without a knowing that deludedly grasps. Liu accepts the absence of deluded grasping but asks that the reason it does not grasp be made clear. The sage's responsive activity is not an empty name: he can guide and transform beings and accord with conditions. The sharpest point of the question therefore emerges here. Although there is no fixed object with which to accord or which to guide, the work of guiding and according with beings still occurs. That “still occurs” is the difficulty.

Third Question: Why Do No Fixed Rightness and No Fixed Fitting Become True Rightness and Perfect Fitting?

The third question seizes on the treatise's statement that when there is no fixed fitting, there is nothing it does not fit, and when there is no fixed rightness, there is nothing that is not right. If there is nothing it does not fit, is that not precisely perfect fitting? If there is nothing that is not right, is that not precisely true rightness? Why, then, continue to speak of fitting without fixed fitting and rightness without fixed rightness?

This is more than a verbal contradiction. Ordinary rightness excludes what is not right, and ordinary fitting fits only a particular thing. The treatise, however, speaks of having no fixed rightness while there is nothing not right, and no fixed fitting while there is nothing not fitted. Liu therefore asks for another simile. If one says only that true rightness differs from ordinary rightness and perfect fitting from ordinary fitting, one has merely separated the language of the awakened from that of the confused without showing how the two relate.

At the End of the Inquiry, Difference Is Still Not Forced into Sameness

On the day the treatise arrived, Liu examined it closely with Huiyuan. At the end of the letter he says that the positions each of them marked seem to have their own grounds, and that perhaps the principles need not all be made entirely the same. This sentence gives the whole inquiry its measure. To grasp the treatise's intention does not mean that every doctrinal position is already identical; to have distinct grounds does not mean that one must immediately declare the positions mutually exclusive.

The force of the letter therefore lies not in giving the answer, but in setting out clearly the three gates through which any answer must pass. Being without knowing cannot abolish illumination. The signless cannot abolish responsive transformation. The absence of fixed rightness and fitting cannot be exchanged for yet another fixed rightness and fitting. Sengzhao's following reply will take up these gates one by one.

Continuation / What Carries Forward

Yuankang does not cover the letter with a system of his own. He first preserves its epistolary sequence, then divides its particular challenges into three questions: whether the substance of wisdom knows or is without knowing; whether the object illuminated has marks or is signless; and whether, when object and wisdom face each other, there is rightness or no rightness, fitting or no fitting. His outline turns an ancient letter into a clear path of reading and prevents later readers from extracting the phrase “prajñā without knowing” and rushing to explain it in isolation.

The Biographies of Eminent Monks preserves the historical setting in which Liu read the treatise, presented it to Huiyuan, and joined him in savoring it before the correspondence began; it also excerpts the opening of the letter. Although that witness does not preserve the three questions in full, it preserves the relationship in which the exchange took place: on one side, a treatise from Kumārajīva's community in Chang'an; on the other, the shared reading of Huiyuan and his companions on Mount Lu. Between these two places, Liu Yimin's letter turns praise into answerable questions and brings the meaning of prajñā without knowing to a sharper point.

Let scripture open the way: does prajñā “without knowing” mean knowing nothing?

Liu Yimin is not asking about an abstract term. His real concern is this: if the sage's mind is darkly still and prajñā is without knowing, how can the sage see the countless differences in the situations of beings, and how can he respond to each occasion? If we answer that the sage knows, we seem to return prajñā to the ordinary person's discriminating mind. If we answer that he does not know, do we not reduce the sage to wood, stone, or empty space?

Sengzhao first sets scriptural testimony between these two extremes: noble wisdom is without knowing, yet there is nothing it does not know; it does nothing contrived, yet there is nothing it does not do. This does not forcibly join knowing and not knowing. It compels us to ask again whether the knowing we ordinarily speak of is limited to grasping the marks of objects, discriminating among them, and choosing or rejecting them. If being without knowing means only the absence of that grasping, it is not benightedness. If non-doing means only the absence of laborious contrivance, it does not mean an inability to respond to things.

Yuankang is careful in judging this line. It conveys the broad meaning of the prajñā scriptures; it is not a complete sentence that can be copied word for word from the Large Prajñāpāramitā Sūtra. The Sūtra of Brahmā's Questions, in speaking of attaining through non-attainment and knowing through having nothing known, opens the same road. Scriptural testimony does not spare the treatise the work of argument. It first places knowing-without-knowing within the language of prajñā, then lets us watch Sengzhao unfold it step by step.

Why does a letter of reply begin with so long a greeting?

The letter does not open at once with the debate over existence and non-being. Sengzhao first says that although one correspondent is ordained and the other a householder, their garb and appearance differ while the subtle principle they seek is not two. Though rivers and mountains keep them far apart, accord with principle makes them neighbours. He then sends greetings to Huiyuan and the ordained and lay practitioners on Mount Lu, and gives a detailed report of the translation assembly in Chang'an: scriptures and eminent monks have arrived from afar; one master has returned with new Vaipulya texts, another translates the Vinaya, another teaches meditation, and another puts the Abhidharma in order.

These are not optional biographical pages wrapped around the doctrinal argument. They give the later phrase “still, yet constantly responding” a living image before the argument even begins. Chang'an has translation halls, monasteries, teachers, and hundreds of disciples. Mount Lu has an ordained and lay community studying together. Rivers and mountains separate the two places, yet Dharma meaning passes between them through messengers, scriptures, hymns, and questions and replies. Having nowhere to lodge does not mean cutting oneself off from human affairs. Dark stillness does not mean withdrawing from the Dharma assembly. The letter itself already shows how one may remain within concrete exchanges without letting the mind be bound by the names and forms of exchange.

Sengzhao also writes this world through the images of walls, moats, and bridges. Yao Xing protects the Three Jewels as walls and a moat protect a city. Faling's journey to obtain scriptures makes him a bridge across a thousand years. Walls and moats allow a Dharma assembly to remain secure; a bridge lets distant places communicate. By the time the formal reply says that the sage's mind passes freely through emptiness and responds through the manifold, the reader has already seen in the first half of the letter how penetration and response take form among people.

The first question: are stillness and illumination really two minds?

Liu Yimin presses the issue to its sharpest point. If the sage brings subtle function to its utmost and darkly accords with truth, do stillness and illumination divide into concentration and wisdom? If his mind is only numinous, still, tranquil, and shining in solitary responsiveness, must its responses to the multitude of occasions cease?

Sengzhao answers that although the two formulations differ, subtle function is always one. Yuankang places the blade between the traces visible to a reader and the sage's own mind. From our view of the traces, motion and stillness differ; in the sage's original mind, they are not two. Seen from outside, silence appears still and response appears active, so we divide two operations into two mental essences. Sengzhao instead asks: if every contact evokes a response and every meeting is penetrated, why manufacture an illumination outside dark stillness, or a stillness outside illumination?

One of the treatise's strongest images is that existence and non-being are like shadows and echoes in the mind. A shadow appears in dependence on a form; an echo arises because of a sound. Neither is the form or sound itself. Existence and non-being are likewise shadows and echoes projected when the mind approaches noble wisdom, while words and images climb upon them in turn. To hear of response and declare that the sage has an existent mind, or to hear of dark stillness and declare that he has no mind, is to seize the shadow and echo and use them to impose a shape on the sage's mind.

Thus, when the sage's mind surpasses names, it is provisionally called non-being; when it meets things as they arise, it is provisionally called existent. Both names are established for the sake of others, not because two fixed parts reside in the sage's mind. This is profound mind silently illuminating: silence does not discard illumination, and illumination does not break silence. It responds to conditions without labor, while its many responses never cease in dark freedom from every lodging.

Neither grasping nor rejecting: why is being without knowing not annihilation?

If we say only “not existent,” a reader can easily slip toward non-being. If we say only “not non-existent,” the reader can just as easily retreat into existence. Sengzhao therefore cuts through grasping and rejecting at once. Because it is not fixed existence, it cannot be grasped; because it is not annihilating non-being, it must not be rejected.

The same cut falls upon the thing itself. To fix a thing as a self-standing thing makes names and forms line up separately. Yet not fixing it as a thing does not erase it. When the treatise says not to thingify things, it does not seek a truth apart from the myriad things. It refuses, right where the thing is present, to seal it within grasping. Non-grasping thus leaves fixed names and forms without a basis, while non-rejection lets the thing before us wondrously remain and directly accord with truth.

Likewise, what the world calls not knowing ordinarily means that wood, stone, or empty space has no awareness. Prajñā without knowing, however, possesses a numinous discernment that illumines the hidden; no subtlety of the Way remains concealed from it. It has neither the ordinary person's grasping knowledge of marks nor the benighted absence of knowing found in wood and stone. Its emptiness does not lose illumination, and its illumination does not lose emptiness. Precisely because existence and non-being do not confine it, motion cannot fix it as existent, nor stillness as non-existent.

Yuankang uses east, west, and the middle to explain neither existence nor non-being. To say that the middle is not east does not immediately establish it as west. To say that it is not west does not immediately establish it as east. “Not existent” only blocks fixed existence; it does not set up fixed non-being. “Not non-existent” only blocks annihilating non-being; it does not set up fixed existence. Read in this way, words that remove attachment do not become new objects of attachment.

The second question: if it illumines only the signless, can it still see beings in all their changes?

The second question comes closer to the work of teaching. If the sage's mind illumines only the signless, does it still see beings changing? If it sees those changes, has it not left the signless behind? Once the two are divided, the sage appears forced to choose: protect emptiness and lose the work of comforting and meeting beings, or enter existence and depart from truth.

Sengzhao does not invent a separate answer. He presses the treatise's own image of form and emptiness to its conclusion. Scripture says that form is not different from emptiness and emptiness is not different from form; form itself is emptiness and emptiness itself is form. If seeing form and seeing emptiness had to be performed separately by two minds, then seeing form would lose emptiness and seeing emptiness would lose form. The word “itself” would have no place to stand.

Not-form, then, does not mean leaving form and observing that empty space is already formless. It means not fixing form as fixed form right within form itself. Yuankang's conclusion is exact: true and conventional do not require different minds, and emptiness and existence do not require different illuminations. To illumine the signless does not lose the work of comforting and meeting beings; to see change does not violate the purport of the signless.

The treatise condenses the answer: change is the signless, and the signless is change. This does not mean that changing appearances do not exist. It means that amid the myriad changes there is no fixed mark to seize. Nor does it make the signless a separate region of blank stillness. The signless is present exactly where the myriad changes do not abide. All day long the sage responds and meets, moves along with things, and takes up each occasion to comfort and teach, yet he never grasps those activities as fixed existence. Only thus do stillness and function genuinely cease to obstruct one another.

The third question: why can true rightness and ultimate fittingness also become a sickness?

Liu Yimin says that only what has no fixed rightness is truly right, and only what has no fixed fittingness is ultimately fitting. Sengzhao does not reject this outright. He adds a strict condition: if the mind does not grasp rightness as right, it can respond to things as right within non-grasping rightness; if it does not grasp fittingness as fitting, it can respond to things as fitting within non-grasping fittingness.

The sickness begins in the next step. If someone fixes true rightness once more as a rightness that can be grasped, or ultimate fittingness as a fittingness that can be grasped, names and forms appear, distinctions between beautiful and ugly arise, and beings chase and contend with one another without end. Words originally meant to loosen grasping have become subtler objects of grasping.

Here Sengzhao leaves one of the letter's clearest images of lived conduct: the sage dwells in the domain of activity and function, yet rests in the realm of the unconditioned; he lives within the world of names, yet makes his home where speech is cut off. He does not flee active functioning, nor is he carried away by it. He does not reject names, nor does he dwell within them. Teaching, judging, and responding continue outwardly, while inwardly no rightness or fittingness is hardened into an intrinsic nature.

The image of words and traces: why does the letter end by asking us to meet beyond the text?

The exchange has become very fine-grained, yet Sengzhao closes by warning that words themselves are precisely where divergent roads may arise. Yuankang explains with footprints and shoes. A footprint is made by a shoe, but it is not the shoe. Words arise from the mind's meaning, but they are not that meaning. If one guards the print without asking who passed this way, a trace changes from a guide into an obstruction.

One skilled in words therefore seeks through words what words cannot say. One skilled in following traces seeks through traces what traces cannot leave behind. This is not an instruction to discard scripture or treatise. It is an instruction not to grasp their attachment-releasing words as another system of fixed names and forms. Yuankang's final sentence gives the direction plainly: seek one another beyond the text; do not cling to the text and use it to raise objections.

Continuation / what carries forward

The Biographies of Eminent Monks preserves the historical scene of this exchange. Liu Yimin read On Prajñā Without Knowing and presented it to Huiyuan. The two examined and savoured it repeatedly, then sent their questions to Chang'an. Sengzhao replied from within the translation assembly. Later, Yuankang divided the reply into greeting, direct answer, and conclusion, then opened the direct answer into its three questions, so that readers would not take this intricate letter for an undifferentiated mass of dark sayings.

Yet what carries forward is not a commentary taking the treatise's place. We must still keep Sengzhao's own three questions before us. Must absence of knowing be benighted? Must the signless lie apart from the myriad changes? Can true rightness be fixed as right? The answers do not depend on setting up another profound realm. They unfold through the treatise's own shadows and echoes, form and emptiness, active functioning, and words and traces. Stillness does not abolish illumination; emptiness does not leave change behind; words are not identical with meaning. At the close, the letter crosses rivers and mountains, while what the two correspondents seek makes them neighbours beyond the written word.

Let scripture open the way: if nirvāṇa is neither existent nor non-existent, are both sides simply discarded?

At the opening of On Nirvāṇa Being Nameless, the reader is brought to the point where speech is about to end: “Nirvāṇa is not existent, yet neither is it non-existent. The road of speech is cut off; the range of the mind's activity ceases.” If this is read merely as “not existence and not non-being,” it is easy to suppose that the author has simply deleted both answers and left a blank. But the explanation that immediately follows is not a blank. It establishes two boundaries that cannot be crossed: “It has that by reason of which it is not existent, and therefore cannot be apprehended as existent; it has that by reason of which it is not non-existent, and therefore cannot be apprehended as non-existent.”

The five aggregates cease forever, and so nirvāṇa cannot be treated as an existent still caught in arising and ceasing. Hidden numinous awareness is not exhausted, and consummate function remains constantly present, and so nirvāṇa cannot be described as the complete annihilation of everything. “Not existent” blocks the attempt to make nirvāṇa into a thing. “Not non-existent” blocks the attempt to make it nothing at all. Only when both removals fall together does “nameless” become visible—not as a void, but as what no fixed name can contain exhaustively.

This also explains why the treatise says that Śākyamuni shut himself in a room, Vimalakīrti closed his mouth, Subhūti disclosed the Way through not speaking, and Śakra and Brahmā ceased listening while flowers rained down. Silence is not an absence of anything to say. What is to be disclosed is precisely what cannot be made an object by words. Yuankang says that the author takes namelessness as his thesis. Namelessness still borrows speech to open the thesis, but no sentence may be reversed into a new enclosing name.

If names cannot transmit it exhaustively, why do the scriptures speak of nirvāṇa with remainder and without remainder?

Examining the Substance raises the reader's most natural objection: scripture plainly uses the two names “with remainder” and “without remainder,” so how can nirvāṇa be nameless? The challenger describes with-remainder as the state in which all entanglements have been exhausted while the karmic-recompense body and noble wisdom remain. Without-remainder is described as the conditions for teaching having ended, body and wisdom extinguished together like lamp-oil and flame both spent. If the two situations are so distinct, surely the names have real referents.

Placing the Substance does not deny the two teachings. It distinguishes what the names indicate from the true substance. With-remainder and without-remainder can indeed mark the manifestation and cessation of traces, but they remain outward names used in responding to things. Consider an echo in an empty valley: someone calls and the echo arises; the call ceases and the echo stops. Or consider an image in a bright mirror: an object arrives and is reflected; it leaves and the image is gone. Because an echo appears, we cannot say a fixed body of sound is hidden in the valley. Because a mirror image disappears, we cannot say the mirror's power of illumination has been annihilated.

The treatise therefore describes the sage's responsive engagement in this way: the Dharma body has no image yet takes form in response to things; prajñā is without knowing yet illumines as conditions arise. Because there is no image, manifested form is not fixed as existence. Because prajñā is without object-grasping knowing, illumination is not fixed as a mind climbing after conditions. A manifest trace is called birth; a trace brought to rest is called death. Birth may be named with-remainder, and death without-remainder. Names are useful where the sage responds to things, but they cannot exceed their own limit and claim to have captured nirvāṇa's true substance.

Does “transcending existence and non-being” secretly establish another existent?

Pressing the Claim of Transcendence seizes upon the most dangerous phrase. If existence and non-being already include everything, does saying nirvāṇa lies beyond them not place a “subtle existent” outside them? If that subtle Way is existent, it remains within existence; if it is non-being, it remains within non-being. As soon as “outside” is understood as a spatial location, the author appears to deny existence and non-being with one hand while secretly setting down a third thing with the other.

Beyond the Realm therefore explains that “transcending” is language that removes, not language that locates. Existence receives its name through non-being, and non-being through existence. High and low, existence and non-being, are formed through mutual dependence. Such mutually dependent existence and non-being can include conventional truth, but they cannot be used to seal nirvāṇa within a fixed definition. To say “transcend” is to ask the reader to release both forms of grasping. It is not to ask the reader to leave existence and non-being and then grasp a more mysterious existent.

Yuankang's blade here is direct. “Not existent” is spoken to cure the sickness of grasping existence. It must not therefore be equated at once with annihilating non-being. The three names of the unconditioned work in the same way: non-being is borrowed to show what is not existent, not to turn nirvāṇa into complete absence. If the name of the medicine is mistaken for the substance of the sickness, the very word meant to remove attachment adds another layer of it.

If it cannot be obtained within existence and non-being or sought apart from them, where can awakening occur?

Seeking the Mystery presses the problem: if nirvāṇa is not within existence and non-being, it cannot be obtained there; if it does not transcend them, it cannot be sought elsewhere. With no direction in which it can be indicated, how can one avoid saying it is entirely absent? Subtle Presence does not provide a new location. It turns the question back toward the dharmas immediately present.

The treatise draws on Vimalakīrti's purport: nirvāṇa is attained without leaving the afflictions. This does not teach anyone to cherish the afflictions. It refuses to construct afflictions and nirvāṇa as two worlds forever cut off from one another. Subtle awakening lies in according with truth immediately within events. To contemplate existence and non-being equally is to stop cutting self away from other. “Heaven and earth share one root with me; the myriad things form one body with me” does not swallow the myriad things into an enlarged self. It releases the opposition “I am here, while truth is somewhere far away.”

The consummate person therefore dwells in existence without being existent and dwells in non-being without being non-existent. Dwelling in existence without being existent, he does not abide in existence. Dwelling in non-being without being non-existent, he does not fall into non-being. He does not leave existence and non-being, and so his response to things has no fixed direction. He does not abide in existence and non-being, and so they cannot enclose the sage's mind. Yuankang explains “subtle presence” as a subtle existence that is neither existent nor non-existent. That “existence” can be understood only through non-abiding; it cannot again be made into something one possesses.

If the unconditioned is one, why do the three vehicles have different depths?

Challenging Difference turns the question toward practitioners. If the ultimate Way is the subtle One without difference, why does scripture say that the three vehicles differ on account of the unconditioned? Distinguishing Difference first guards the non-duality of what is realized, then returns difference to practitioners. There are not three safe places outside the burning house, though the vehicles used to leave it differ. There are not three farther shores, though the capacities, wisdom, and residual habits of those who cross have different depths.

The doctrinal passage of the Lotus Sūtra is condensed in the treatise: the foremost great Way has no two right paths; for the indolent, the Tathāgata uses skillful means and speaks of three divisions within the one vehicle. The point is not to force the one and three vehicles into the same name. It is to distinguish the expedient name from ultimate convergence. All three vehicles leave birth and death and so are called unconditioned. Their ways of travel differ, so three names are established. Three names do not mean that the true substance of the unconditioned has been cut into three pieces.

The timber simile is especially exact. Cut away a foot and the timber is a foot shorter; cut away an inch and it is an inch shorter. The difference in measure lies in the timber, not in the empty space outside it. How much beings have severed their bonds and whether their residual habits are exhausted belong to practitioners, not the unconditioned. To transfer the practitioner's difference to the farther shore would fragment the undifferentiated Way. To deny differences in depth because the shore is undifferentiated would erase the real sequence provisionally established in scripture.

Are the person and the unconditioned one or other? How do the three birds release both alternatives?

Pressing Otherness refuses to let the previous answer pass easily. If I am the unconditioned, how can one say the unconditioned is without difference while difference lies in me? If I differ from the unconditioned, I remain forever within the conditioned and no dark coincidence can occur. If they are one, the three vehicles appear impossible; if other, realization appears impossible.

Reconciling Otherness does not force an abstract phrase upon the problem. It releases three birds from a net. All three arrive in the realm free from danger. Freedom from danger is the same, yet the birds remain distinct. The birds' difference cannot divide freedom from danger into three. The sameness of freedom from danger cannot press the three birds into one. The treatise says that three birds leave the net and together reach the realm free from danger. Yuankang calls the simile clearly visible because it guards both accord and difference at once.

“I go to the unconditioned and thus am the unconditioned” means that realization no longer leaves two separate domains standing between them. “The unconditioned is one while persons are not one” means that realization does not erase the capacities of the three vehicles. This is neither the otherness of an “I” standing outside the unconditioned nor the sameness of three persons dissolving into one person. How could freedom from danger differ? Difference belongs to the birds. How could the unconditioned differ? The difference lies in practitioners who have not yet exhausted it.

If all three arrows strike and all three animals cross, why speak of gradual realization?

Pressing Graduality asks again: the two vehicles gain the knowledge of exhaustion and bodhisattvas gain the knowledge of non-arising. Once deluded thought and bonds are removed, no obscuration should remain. The unconditioned is equal and non-dual; how, then, can one realize its substance without exhausting it? The answer again takes up the treatise's own images: three arrows strike the target, and three animals cross the river.

All three arrows hit the target, yet they enter it to different depths. Elephant, horse, and hare all cross the river, yet they enter the water to different depths. What is struck or crossed need not be divided into three for strength to differ. The three vehicles alike contemplate the four truths, cross dependent arising, and rise into the unconditioned, yet wisdom's power need not become equal at once. This answer guards both sides. Gradual cultivation does not give grades to the unconditioned, while the equality of the unconditioned does not make the sequence of practice unreal.

The extra-Buddhist current of daily increase in learning and daily decrease in pursuing the Way is used only to show decrease upon decrease. Sengzhao does not replace scriptural proof with a work of the Masters. He borrows a familiar sentence to say that deep bonds cannot be imagined wholly exhausted merely by invoking “original equality.” Firefly and sun alike give light, yet their illumination is not equal. In the same way, a common destination does not make wisdom's functioning equal.

Once mind and wisdom are stilled, does further cultivation become movement again?

Deriding Motion poses the difficulty closest to daily practice. If those above the level of the Dharma body have entered the unconditioned, surpassed the aggregates and sense-fields, and stilled mind and wisdom, why do they still cultivate through three stages and accumulate ever broader virtue? Further cultivation seems to require preference; accumulating merit seems to require choosing, rejecting, gain, and loss. To place cessation and cultivation within the same person, the challenger says, is to point south and call it north.

Motion and Stillness first gathers the answer into one sentence: the sage is unconditioned yet leaves nothing undone. If unconditioned is read as doing nothing, the sentence contradicts itself. If doing is read as intentional contrivance, it likewise violates cessation. Sengzhao means that, because he is unconditioned, the sage is constantly still while moving; because he leaves nothing undone, he is constantly moving while still. Motion and stillness are not two periods, first stopping the mind and then starting it again. Responsive conduct does not arise from a deluded, appropriating mind.

Thus the Daoxing says that mind is neither existent nor non-existent. The ordinary person's existent mind stops in deluded thought, while the mindlessness of empty space cuts off illumination. The sage's mind falls into neither. Because it is not existent, every deluded thought ceases. Because it is not non-existent, there is no principle with which it does not accord. Because it accords with every principle, the myriad virtues can become vast. Because deluded thought is wholly extinguished, achievement does not return to a self. This is the hinge disclosed by the Youthful Ascetic's offering of flowers and the bodhisattva practicing emptiness saying, “Now is the time for practice.” The emptier the mind, the broader the conduct. Acting throughout the day does not violate non-action.

If nirvāṇa is attained only later, does it have a beginning and an end?

Exhausting the Source brings time into the challenge. If beings exist first and attain nirvāṇa only after riding the three vehicles, nirvāṇa appears to begin. What has a beginning should also end, so how can nirvāṇa be clear like space and without beginning or end? Comprehending Antiquity does not push nirvāṇa back to a time before beings were born and claim that a finished object had already been placed there. It says instead that the sage has no fixed substance of his own and takes the myriad things as his body. Principle and the sage are not different; things and self are not different; antiquity and the present, beginning and end, become one body in subtle accord.

Scripture says that seeing dependent arising is seeing Dharma and seeing Dharma is seeing the Buddha. It also says that nirvāṇa is attained without leaving dharmas. Seeing Dharma through dependent arising means not leaving truth outside the coming and going of the myriad things. Attaining nirvāṇa without leaving dharmas means not cutting birth and death from nirvāṇa as two places arranged before and after.

The goddess asks Śāriputra how long liberation has lasted. If liberation itself has no measurable duration, nirvāṇa cannot be placed on a timeline and said first not to exist, then to be attained, and finally to disappear. This does not deny the course of practice. It refuses to make the principle with which practice accords into a thing that arises and ceases in time.

When the five aggregates are exhausted, who is the attainer?

Examining Attainment is the last of the nine rebuttals and tightens all the earlier questions at once. If the nature of beings exists only within the five aggregates, beings end when the aggregates end. If nirvāṇa stands independently outside the three realms, beings and nirvāṇa occupy two domains. Who crosses the boundary to acquire it? If an attainer remains, a being must extend beyond the five aggregates. If the aggregates are indeed wholly exhausted, an attaining subject cannot be established.

Mysterious Attainment does not add a spiritual entity outside the five aggregates, but neither does it declare that there is absolutely no person and no Way. It first dismantles the grammar “a being acquires a nirvāṇa.” If nirvāṇa is discussed from nirvāṇa itself, no dharma can be excluded from it. Who alone is not nirvāṇa and therefore must acquire it elsewhere? Vimalakīrti questions Maitreya by saying that all beings are stilled in their own nature and do not undergo another cessation. This does not treat one who has not practiced as one who has practiced. It says that cessation cannot become a real object added afterward.

The Fangguang therefore examines in turn attainment, non-attainment, both attainment and non-attainment, and freedom from both, and finally says that because there is non-attainment, it is called attainment; what is attained is non-attainment. Attainment as non-attainment is not a fifth answer established beyond the four alternatives. It simply brings the attachment to acquisition to rest. Truth arises through freedom from attachment, falsity through attachment. Only when the enclosing opposition between attaining subject and attained object is released can the roads of the three vehicles remain open and the purport of namelessness avoid collapsing into non-being.

Continuation / what carries forward

Through its memorial, On Nirvāṇa Being Nameless joins Kumārajīva's community with the age in which Yao Xing sought the Way. Through its nine rebuttals and ten expositions, it repeatedly sharpens a single question: as soon as nirvāṇa is spoken of, names cannot be avoided; as soon as a name is grasped as substance, nirvāṇa has already been left behind. Yuankang preserves each rebuttal and exposition chapter by chapter. His outline shows that the nineteen chapters are not diffuse conversation about mystery, but a rigorous exchange of nine challenges and nine answers, gathered under the governing exposition of Opening the Thesis.

What the treatise carries forward is not a formula, “neither existent nor non-existent,” that can replace practice and realization. It carries a way of reading that permits no resting in either extreme. To speak of namelessness must not fall into non-being; to speak of responsive engagement must not fall into existence. To speak of the unconditioned must not abolish conduct; to speak of continued cultivation must not establish a deluded, appropriating mind. To speak of differences among the three vehicles must not split the unconditioned; to speak of ultimate non-difference must not erase different depths of wisdom. At the end, even non-attainment must not be seized as something attained.

The deepest teaching of the whole treatise therefore does not lie in finding a better name for nirvāṇa. It lies in seeing, whenever a name arises, how far it can point and where it must be released. A name can guide the way, but it cannot become the place reached. Nineteen chapters can expound, but they cannot lock the nameless substance inside sentences. Read this way, the nine rebuttals do not destroy and the ten expositions do not add. Each rebuttal breaks one layer of attachment; each exposition returns the reader to the dharmas immediately present, neither leaving them nor abiding in them.
