中論 釋僧叡序

“Middle” is a name that points toward the true mark; “treatise” is an expedient that explains the path. Names and words are useful, but neither is a substantial thing to grasp. Seng Rui is concerned not only with worldly inversions concerning existence and nonexistence, but also with practitioners who retreat into a narrow wisdom of aversion. Unless illumination is vast, the Way and the conventional obstruct one another. Unless understanding is thorough, the two extremes cannot dissolve.

The received work also has a clearly articulated textual stratigraphy: Nāgārjuna composed the verses, Qingmu wrote the commentary, and Kumārajīva’s translation workshop edited and supplemented it. Only by preserving these three levels can one read the treatise in full without passing commentary off as the treatise author’s own speech. The Treatise on the Middle, the Hundred Treatise, the Great Treatise on the Perfection of Wisdom, and the Twelve Gate Treatise illuminate one another while applying their force in different ways. What they share is the opening of a gate beyond clinging, not the fabrication of another “middle” to hold on to.

The Treatise on the Middle consists of five hundred verses composed by the bodhisattva Nāgārjuna. It bears the name “Middle” in order to illuminate the true mark of all dharmas, and it is called a “treatise” in order to articulate fully what can be said. Since the true mark is difficult to awaken to without recourse to words, the name “Middle” is provisionally entrusted with pointing it out. Since discourse cannot exhaust its meaning without explanation, reasoned exposition is used to make it clear. Once the true mark has been shown and the meaning of the words explained, the sphere in which bodhisattvas practice and the place of awakening illumines can be understood in full clarity.

Sentient beings become mired in delusion because inverted views arise, and so they sink within the three realms. Some gain a measure of understanding, yet the narrow wisdom of aversion leaves them standing aloof and alone, still estranged from the great Way. From this we can see that great awakening lies in a vast and unobstructed illumination, whereas lesser wisdom is bound by the confines of a constricted mind. Unless illumination is vast, it cannot comprehend existence and nonexistence, the Way and the conventional, on equal terms. Unless understanding is thorough, it cannot travel the Middle Way and dissolve both extremes. That the Way and the conventional are not level with one another, and that the two limits do not disappear, is precisely what concerns the bodhisattva.

The great Nāgārjuna therefore analyzes all dharmas through the Middle Way, so that those who follow delusion may glimpse the hidden purport and turn around. He also gathers everything into the teaching of the present moment, so that those of deep understanding need not pursue it through further questions but can penetrate it here and now. The road opened by this treatise is broad and level: one might say that it lays a straight path across the most hidden stages and throws open the subtle gate between heaven and earth. It sends the wind of wisdom through withered branches and pours ambrosia into those who have grown faint.

Once a lofty terrace of a hundred beams has been built, the crampedness of a thatched hut becomes obvious. In the same way, encountering the breadth of this treatise reveals the poverty of a narrow understanding. Happily, China has suddenly received this Dharma gate from Vulture Peak as a firm stronghold, and even those whose dispositions are crooked, perilous, and confined receive the lingering benefit of its flowing light. From this time onward, worthy people who speak of the Way can at last investigate the true mark together.

It is said that throughout the lands of India, no one counted among the learned fails to ponder the Treatise on the Middle repeatedly and regard it as essential. Many have also taken up the brush to explain it. The commentary translated here was written by the Indian brahmin Piṅgala, known in Chinese as Qingmu. Although Qingmu had deep faith in and understanding of the true Dharma, his phrasing was not always elegant or well judged. Wherever the meaning was defective or the wording cumbersome, Master Kumārajīva edited and supplemented it, making its communication of the sūtra’s meaning comprehensive, though the composition still occasionally falls short of perfection from one passage to the next.

The Hundred Treatise chiefly counters the erroneous teachings of non-Buddhists, bringing external deviations to rest. The Treatise on the Middle removes obstructions within the Buddha’s teaching, allowing its meaning to flow freely. The Great Treatise on the Perfection of Wisdom is vast in learning, while the Twelve Gate Treatise is profound and exact. To trace these four treatises is like having the sun and moon shine into one’s breast: nowhere remains obscure. I turned them over in my mind again and again and could not put them down. Forgetting my own coarseness and clumsiness, I therefore entrusted what I gained from reading the treatise to this preface and placed a statement of each chapter’s purport at the head of the scroll. How would I dare claim that I can explain the Treatise on the Middle? I merely rejoice that my mind has found a point of accord.

Canonical Grounding First: A Name Is a Gate, Not Something to Grasp

Seng Rui begins by saying that the Treatise on the Middle is named “Middle” to illuminate the true mark and called a “treatise” to explain the meaning of its words. The true mark is not the word “Middle” itself, yet words must be borrowed to lead people toward awakening. Discourse is not the true mark itself, yet exposition must be borrowed to make the path clear. This opening establishes a boundary for the whole treatise: names and words can guide, but they cannot in turn become substantial things to which one clings.

If the Extremes Are Existence and Nonexistence, How Can Practice Itself Also Become One-Sided?

The concern expressed in the preface is not limited to worldly wrong views. Inverted views immerse people in the three realms, but a narrow wisdom of aversion may also leave a practitioner aloof and isolated. If one’s illumination is not vast enough, existence and nonexistence, the Way and the conventional, cannot be comprehended on equal terms. If one’s understanding is not thorough enough, one cannot travel the middle course and dissolve the two limits. The Middle Way is therefore not a compromise chosen between existence and nonexistence. It is the seeing that both extremes stand only in mutual dependence, so that the Way and the conventional no longer bar one another.

If Reasoned Exposition Refutes Everything, How Can It Still Become a Path?

Seng Rui praises Nāgārjuna for “analyzing them through the Middle Way.” This makes clear that critical analysis is not meant to leave a wasteland behind. The treatise dismantles congealed views layer by layer, allowing those lost in fixed directions to glimpse its purport and turn around. It then draws understanding back into the teaching of the present moment, so that one need not seek an answer somewhere beyond concepts. What refutation removes is constricted clinging. What appears when it has been removed is a broad, level, practicable road.

Whose Voice, Exactly, Do We Hear in the Treatise on the Middle Before Us?

The preface draws a crucial textual boundary: Nāgārjuna composed the verses, Qingmu wrote the commentary, and Kumārajīva’s translation workshop edited places in Qingmu’s commentary that were defective or cumbersome. A reader of this work therefore cannot treat the verses alone as the entire Treatise on the Middle, nor quietly present Qingmu’s commentary as Nāgārjuna’s self-commentary. Verse, commentary, and translation workshop all inhabit the same transmitted text; each has its own identity, and together they make the book.

Because Qingmu commented and Kumārajīva edited what was defective or cumbersome, a reader hears more than one voice: the verses state the meaning established by Nāgārjuna, the commentary opens it through Qingmu’s explanation, and the translation workshop has made editorial interventions between them. Chinese transmission has preserved all these strata, but they cannot be collapsed into a single conclusion with no discernible author. The more clearly they are distinguished, the less likely a later explanation is to eclipse the wording of the root verses.

Carried Forward: Jizang’s Mirror

Jizang’s commentary on the preface carries forward the transmission account of “five hundred verses” and opens the meaning of the preface line by line. This mirror reminds us that ancient masters already treated the preface as part of the work as transmitted, not as a dispensable appendix. Yet a mirror serves to reveal the transmission and purport already present in the preface; it does not impose a different history upon it.

Seng Rui closes by placing the Hundred Treatise, the Treatise on the Middle, the Great Treatise on the Perfection of Wisdom, and the Twelve Gate Treatise side by side: one treats external error, one clears internal obstructions, one is vast, and one is profound and exact. This does not flatten four treatises into one. It offers a common path of reading. Entering the Three Treatises through this preface, the first discipline to learn is precisely this measure: let the treatises illuminate one another without causing any one of them to lose its own voice.
