Sudden and Gradual

I. Introduction: A Non-Graded Concentration — Sudden, or Gradual?

The preceding paper stopped with Bodhidharma. Bodhidharma renamed "concentration" a pacifying of the mind (安心) — abiding fixedly in wall-gazing, entering by principle and by practice, in tacit accord with Huike's "I have searched for the mind and cannot find it at all"; Zongmi judged this a concentration set outside the four jhānas and eight attainments. That was where Chan first walked off the ladder of the four jhānas: concentration was no longer a station of attainment to be climbed rung by rung, entered and exited, but was rewritten as a kind of native abiding of the mind.

A non-graded concentration, however, runs at once into a structural question. When this "pacifying of the mind" passed into Hongren's East Mountain Dharma Gate (東山法門) and then, through his disciples, branched into a Southern and a Northern line, the question surfaced with peculiar clarity: this concentration that is no longer a graded station — is it had suddenly, ready-made, or attained gradually, by wiping clean? Shenxiu and Huineng each answered with a verse, and the two verses split "how concentration is attained" into two roads; and Huineng, in the Platform Sūtra's chapter on concentration and wisdom, "concentration is the substance of wisdom, wisdom the function of concentration," went on to rewrite the relation between concentration and wisdom itself.

Two things must be said plainly at the outset, lest this paper be read as something it is not.

First, this paper does not rank the sudden above the gradual, or the gradual above the sudden. The sudden and the gradual, South and North, Huineng and Shenxiu are presented here side by side, with no single line taken as orthodox and no lineage asserted to be superior. This is not a watered-down compromise but a position with textual warrant: as will be seen, the Platform Sūtra itself holds that "the Dharma has no sudden or gradual; persons have sharp or dull faculties," construing sudden-and-gradual as a difference in the faculties of those who receive the Dharma, a provisional designation; and modern scholarship on Chan history has repeatedly shown that the "Southern-sudden, Northern-gradual" opposition, and the verdict "gradual equals inferior," are to a large degree a later construction of lineage polemic, not the Northern school's account of its own teaching. To refuse to rank is precisely to avoid repeating that known distortion.

Second, this paper is not written as a manual. The words sudden, gradual, concentration-and-wisdom, no-thought are handled here uniformly as objects of doctrine and of history — what they are, how the tradition has interpreted them, where the texts diverge — and not as instruction in "how to awaken suddenly" or "how to practise no-thought." This is the same sister-discipline as the previous paper's "not how to face a wall": wherever a passage could be read as a sequence of steps, it is rewritten as "what it is."

So the question this paper sets is a question on the side of concentration: when Chan disputes the sudden and the gradual, what, seen from the side of concentration, is being disputed? The answer is — the manner in which concentration is attained. Along this question the paper proceeds: first, how the two verses split that manner of attainment into two roads (§II); then how Huineng, by the substance-and-function formula, rewrites the relation of concentration and wisdom (§III); then how the Platform Sūtra itself refuses to rank the sudden and the gradual as higher and lower (§IV); then the restoring of the Northern school's concentration to its true face (§V); and finally Zongmi's synthesis, "sudden-and-gradual lies in the capacity" (§VI).

II. The Two Verses: Two Ways Concentration Is Attained

The best-known scene in the Platform Sūtra is the story of the "mind-presenting verses" among the disciples of the Fifth Patriarch — Shenxiu writing his verse on the corridor wall, Huineng (who could not read) having another verse written for him, and the Fifth Patriarch transmitting the robe and the Dharma by night. It must be said first: this corridor-wall verse contest, together with the midnight transmission, is broadly taken by scholarship to be a stratum of later biographical elaboration, its historical substance hard to fix.¹ This paper sets that historical dispute aside, adjudicating neither who came first nor what is genuine, and reads the two verses only as texts — each setting forth one reading of concentration.

Shenxiu's verse (Zongbao recension):

The body is the bodhi-tree; the mind is like a bright mirror's stand. Wipe it clean time and again, and let no dust alight.²

This verse likens the mind to a bright mirror. A mirror can reflect — figuring the mind's native power of awareness; but a mirror gathers dust, and so must be "wiped clean time and again." On this reading, concentration is an ongoing work of maintenance: the mind is the mirror's stand, deluded thoughts are the dust, and concentration is the unbroken act of wiping the dust away to keep the mirror bright. It presupposes a subject who wipes, a mirror that is wiped, and a layer of dust to be wiped — concentration is the cleansing work carried on, again and again, among these three. This is the gradual gate's reading of concentration: concentration is a maintenance accumulated step by step, not to be had at a single stroke.

Huineng's verse must give us pause here, for it is the single most famous textual variant in the history of Chan, and the two recensions are sharply different in metaphysical register and may not be flattened into one.

The Dunhuang recension (compiled around the end of the eighth century) gives Huineng's reply as two verses, of which the key lines run:

Bodhi has at root no tree; the bright mirror, too, has no stand. The Buddha-nature is ever pure — where could there be any dust?³

The current Zongbao recension (Yuan dynasty) gives one verse, with a wholly different third line:

Bodhi has at root no tree; the bright mirror, too, is no stand. Fundamentally there is not a single thing — where could any dust alight?⁴

Both verses are readings of the sudden gate — both directly negate the "mirror-stand and dust" structure that Shenxiu's verse presupposes: there being neither tree nor stand, there is nothing to wipe. On this reading, concentration is not wiped into being but has at root no dust to wipe; concentration is not a state to be reached but the already-present self-nature. Yet the metaphysical register on which each grounds its negation differs. The Dunhuang "the Buddha-nature is ever pure" appeals to a Buddha-nature natively pure and ever showing forth (the affirmative idiom of the tathāgatagarbha line), concentration being the spontaneous disclosure of this pure Buddha-nature; the Zongbao "fundamentally there is not a single thing" appeals to emptiness — sweeping away even that "ever-pure Buddha-nature" along with all else, concentration being the setting-up of nothing upon "not a single thing." The former breaks the dust by way of "being" (an ever-pure nature); the latter by way of "non-being" (nothing there at root).

This variant is no trifle of textual collation but the hinge of the present paper. To follow the common habit and cite only the Zongbao "fundamentally there is not a single thing" would be to let the later idiom of emptiness cover over the early tathāgatagarbha idiom of the Dunhuang stratum, and to read the sudden gate as a single, fixed position. Only by setting the two recensions side by side does one see that the sudden gate has, within itself, a metaphysical tension — and just this is the reminder that the parting of sudden from gradual is far from a clean line.⁵

(Shenxiu's fourth line, too, has recension variants: the Dunhuang recension reads "let no dust be," the Zongbao recension "let no dust alight"; the commonly transmitted "let no dust alight" in the negative form of the Dunhuang line is a conflation of the two, and is not followed here.⁶)

III. [Pivot] Concentration-and-Wisdom as Equal Study: Concentration Is the Substance, Wisdom the Function

The two verses split the manner in which concentration is attained into two roads, but Huineng's real contribution does not stop there. In the Platform Sūtra's chapter on concentration and wisdom, he carries the question forward from "how is concentration attained" to "what is the relation between concentration and wisdom" — and this step is the most central proposition along the axis of concentration.

The Zongbao recension, "Concentration and Wisdom," the fourth chapter:

This teaching of mine takes concentration and wisdom as its root … Concentration and wisdom are one substance, not two. Concentration is the substance of wisdom; wisdom is the function of concentration. At the very moment of wisdom, concentration is within the wisdom; at the very moment of concentration, wisdom is within the concentration. To understand this meaning is concentration-and-wisdom as equal study … Do not say that concentration first issues wisdom, or wisdom first issues concentration, as two separate things.⁷

The Dunhuang recension, at the same place:

Taking concentration and wisdom as the root … concentration and wisdom are one in substance, not two. Concentration just is the substance of wisdom; wisdom just is the function of concentration … this meaning is concentration-and-wisdom equal.⁸

The weight of this passage lies in its cancelling of any before-and-after, or any separateness of substance, between concentration and wisdom. The usual way of speaking about calming and contemplation, concentration and wisdom, has often imagined concentration as the rung cultivated first — first to gain concentration, then to have concentration "issue" wisdom; concentration the cause, wisdom the effect, the two set in temporal sequence and divided in substance. Huineng denies this architecture outright: concentration and wisdom are not two stations cultivated one after the other but the substance and function of one and the same thing. "At the very moment of wisdom, concentration is within the wisdom; at the very moment of concentration, wisdom is within the concentration" — when wisdom is present, concentration is within that wisdom; when concentration is present, wisdom is within that concentration; the two cannot be split into a "concentration first, wisdom after" or a "wisdom first, concentration after."

Huineng at once illustrates this "one substance-and-function" with a homely simile:

What are concentration and wisdom like? They are like a lamp and its light. Where there is a lamp there is light; where there is no lamp there is darkness. The lamp is the substance of the light, the light the function of the lamp; in name they are two, but in substance they are fundamentally one.⁹

The lamp and its light — the lamp is the substance, the light the function, but at the instant the lamp is lit the light is there together with it, with no interval of "first a lamp, and after a while the light." Concentration is to wisdom as the lamp is to its light: in name they may be parted into substance and function, but in fact they arise together at one moment and are fundamentally one thing.

This is Huineng's rewriting of concentration. With Bodhidharma, concentration was renamed a "pacifying of the mind" and moved off the four-jhāna ladder; with Huineng, concentration is rewritten a step further, as "the function that is one substance with wisdom" — no longer a work to be cultivated in isolation and then made to give rise to something else (wisdom), but the side already present at the very moment wisdom arises. "Concentration-and-wisdom as equal study" is just the call to stop conceiving the two "as two separate things, concentration first issuing wisdom, or wisdom first issuing concentration."

One thing must be added in passing. This same passage of the Platform Sūtra's chapter on concentration and wisdom also contains the celebrated section on the one-practice samādhi ("in all times, walking, standing, sitting, lying, ever to practise the upright mind," and so on). The scriptural sourcing of the one-practice samādhi (ekavyūha-samādhi), Daoxin's reception and transplanting of it, and the various Chan interpretations of it belong to another axis — the axis of mindfulness — and are not unfolded here; it is noted only as background that the text places the one-practice samādhi and concentration-and-wisdom-as-equal-study together in one chapter, while what this paper expressly takes up is the latter: the substance-and-function relation of concentration and wisdom.¹⁰

IV. [The Non-Ranking Spine] The Dharma Has No Sudden or Gradual; Persons Have Sharp or Dull

If the sudden gate and the gradual gate read concentration so differently, does it follow that the two must divide into higher and lower, that one must win? The Platform Sūtra's own answer is no — and this is exactly the textual warrant for the present paper's refusal to rank.

The Zongbao recension, "Sudden and Gradual," the eighth chapter:

The Dharma is at root one school; persons have South and North. The Dharma is of one kind; seeing has slow and quick. What is named sudden and gradual? The Dharma has no sudden or gradual; persons have sharp or dull faculties — hence the names "sudden" and "gradual."¹¹

The Dunhuang recension, to the same sense (with a slight difference of word order):

The Dharma has no gradual or sudden; persons have sharp or dull faculties — hence the names "gradual" and "sudden."¹²

Both recensions alike construe sudden-and-gradual as a difference in the faculties of those who receive the Dharma, not a hierarchy of the teaching itself. The Dharma is of one kind only; what is called sudden or gradual is so because the sharp-faculty person sees quickly and the dull-faculty person sees slowly — slow and quick lie in the person, not in the Dharma. Elsewhere the Platform Sūtra says still more directly that sudden and gradual are a "provisional designation": "The deluded cultivate gradually; the awakened accord suddenly … and so the provisional names 'sudden' and 'gradual' are set up."¹³ Being provisional names set up on account of sharp and dull faculties, sudden and gradual are not two mutually competing attainments to be graded as better and worse, but two speeds at which one and the same Dharma shows forth in faculties of different kinds. The Dunhuang recension goes so far as to say that "both sudden and gradual alike set up no-thought as their principle" — the sudden gate and the gradual gate revere one and the same governing principle, their divergence lying only in the quickness or slowness of arrival.¹⁴

This "referring the difference to the faculty, not to the teaching" finds its clearest pairing, along the axis of concentration, in the chapter on Zhicheng. Zhicheng was originally a disciple of Shenxiu, sent to spy out Huineng; through this scene the Platform Sūtra places Shenxiu's concentration and Huineng's side by side:

[Shenxiu teaches people …] purifying one's own intent is called concentration … [Huineng says:] my precepts, concentration, and wisdom guide people of the Supreme Vehicle. Awakening and understanding differ, and seeing has slow and quick … all arising in function from the self-nature — this is the true Dharma of precepts, concentration, and wisdom.¹⁵

Shenxiu's concentration is "purifying one's own intent" — an act of cleansing the mind's intent, of a piece with the logic of wiping the bright mirror: concentration is a work of purification carried on upon the mind. Huineng's concentration is "arising in function from the self-nature"; he gives his own verse as "the mind-ground undisturbed — that is the self-nature's concentration" — concentration is not a purifying of anything, but the disclosure of that side of the self-nature which is natively undisturbed.¹⁶ Two concentrations, the one an act (purifying the intent), the other a self-nature (natively undisturbed).

But the decisive point is this: Huineng, within the same passage, at once refers the difference to faculty — the difference between "guiding people of the Great Vehicle" and "guiding people of the Supreme Vehicle," "awakening and understanding differ, and seeing has slow and quick." That is, Huineng does not say that his own concentration is superior to Shenxiu's, but that the two guide faculties of different kinds, and so show forth a different quickness or slowness. The difference is referred consistently back to "persons have sharp or dull faculties," not directed toward "the teaching has higher and lower."

A note on recension is needed here. The chapter on Zhicheng also contains a much-cited saying of Huineng's that judges the seated-meditation method of Shenxiu's line to be a disease:

[Recounting Shenxiu's teaching of "fixing the mind and contemplating stillness," he says:] fixing the mind and contemplating stillness is a disease, not Chan; binding the body in long sitting — what does it profit the principle?¹⁷

It must be marked clearly: this passage (together with the pairing of "purifying one's own intent is called concentration" and "the mind-ground undisturbed — the self-nature's concentration") is found only in the Zongbao recension's Encounter-Circumstances chapter, and is absent from the Dunhuang recension; it is to be cited as a developed form of the Zongbao (Yuan dynasty) text, not taken outright as the words of a Huineng of around the end of the eighth century, still less as a seventh-century record of fact.¹⁸ And what is criticised here is a method — forcibly binding the body in sitting and fixing the mind to "seek" a state of still concentration — not in order to rank the sudden gate above the gradual. Read from the side of concentration, the edge of this saying is this: if concentration is understood as a static state of entered stillness, one that must be held by forced sitting, it falls into the "disease of fixing the mind and contemplating stillness." This is one piece of counter-evidence for "concentration is not static absorption," resonating faintly with the proposition this paper carries from the preceding one (that concentration must turn back toward prajñā, that a purely absolute concentration is not ultimate) — but this pointing is only a lightly placed lead; its positive resolution belongs to the volume's sealing paper and is not unfolded here.

V. The Northern School's Concentration: Restoring Its True Face

To hold to "no ranking," the Platform Sūtra's own self-attestation is not enough; one must also make the positive case for the Northern school's doctrine of concentration. Otherwise the "gradual gate" gets written, all but unawares, into a gradualist strawman — a foil that does nothing but wipe mechanically and grasps nothing of the sudden import. The fact is otherwise.

The Northern school had its own coherent and subtle doctrine of concentration; the concentration set forth in its representative text, The Expedient Means of Birthlessness in the Mahāyāna (a Dunhuang manuscript, of the East Mountain Dharma Gate–Shenxiu line), is in no way caricatured by the two words "wiping clean." Its opening declares:

What is meant by "awareness" is that the mind in its essence is free of thought. Freedom from thought is buddhahood.¹⁹

"Freedom from thought" — the mind in its essence is of itself free of thought, and freedom from thought just is buddhahood. This is no longer the image of "wiping dust from a mirror time and again," but a direct pointing to the mind-essence's native freedom-from-thought. The text says further:

In a single thought, the purified mind suddenly transcends to the stage of buddhahood.²⁰

Note that word "suddenly" — the Northern school's own text says plainly "suddenly transcends to the stage of buddhahood." The impression that "the gradual gate has no sudden" does not hold up before the Northern school's own text. As for the Northern school's well-known "contemplating purity," it too is no dull, fixed staring at one spot, but a kind of spatial pervasion:

Contemplate purity, look closely; use the pure mind's eye, gazing far without bound or limit.²¹

"Use the pure mind's eye … without bound or limit" — this is a pervading gaze toward the boundless with a purified mind's eye, and at its terminus stands not far from the "no-thought" of which the Southern school speaks.²² The Northern school's concentration is a gate of "freedom from thought," its import lying in the mind-essence's native freedom-from-thought and purity, not in a mechanical sweeping-away of deluded dust.

Historically, the Northern school was at the time no marginal offshoot — quite the contrary. Shenxiu's line, in its own Record of the Masters and Disciples of the Laṅkā[vatāra], traces its descent from Hongren's "East Mountain Dharma Gate" and was taken as the orthodox line below Bodhidharma; Empress Wu Zetian summoned Shenxiu to the capital and honoured him highly, and the saying of the time ran, "if one would speak of cultivating the Way, there is nothing beyond the East Mountain Dharma Gate" — the Northern school, from the end of the seventh century into the early eighth, was the establishment orthodoxy of the Chan gate. The opposition-structure called "Southern-sudden, Northern-gradual," and the verdict "gradual equals inferior," are to a large degree a later discourse constructed and propagated by Shenhui's line, not the Northern school's account of its own teaching.²³

Concerning Shenhui, a word is needed by way of indication, and not of endorsement. Shenhui, at Huatai (732 CE), set forth his Determining the True and False about the Southern School of Bodhidharma, which positively constructed the "Southern-sudden, Northern-gradual" opposition and disparaged the Northern school as "its lineage collateral, its teaching gradual"; this discourse was later inherited by Zongmi in his Chart of the Master-Disciple Succession of the Chan Gate (where the Northern school is called "only gradual cultivation, wholly without sudden awakening").²⁴ This paper cites Shenhui's treatise only as a characterisation — to point out that the configuration of "ranking the sudden and the gradual" has its origin in lineage polemic, that it is an inherited polemical rhetoric and not a doctrinal necessity — and in no way takes Shenhui's verdict as this paper's own judgement of the Northern school. It is telling that the same Zongmi, elsewhere (see the next section), moves sudden-and-gradual back from "the substance of the Dharma" to "the capacity," giving a synthesis whose register is the opposite of Shenhui's ranking.

VI. Conclusion: Bodhidharma Named Concentration, Huineng Rewrote the Concentration–Wisdom Relation, Zongmi Placed Sudden-and-Gradual in the Receiver

Strung together, Chan's re-conception of concentration proceeds step by step. As the preceding paper showed, Bodhidharma renamed concentration a pacifying of the mind and moved it off the ladder of the four jhānas and eight attainments — the starting point at which Chan walked off the four-jhāna ladder. As this paper has shown, Huineng went further and rewrote the relation of concentration and wisdom — by the equal-study formula "concentration is the substance of wisdom, wisdom the function of concentration," cancelling the before-and-after and the separateness of substance in "concentration first issuing wisdom," and rewriting concentration from a work cultivable in isolation, that then gives rise to wisdom, into a side that arises as one substance with wisdom. Bodhidharma named concentration; Huineng rewrote the concentration–wisdom relation: this is the second step in Chan's re-conception of concentration after its departure from the four-jhāna ladder.

The limit of this paper must be defined. This paper only establishes Huineng's concentration-and-wisdom-as-equal-study and the substance-and-function formula (confined to the specific proposition of this one patriarch). The doctrinal summation of "the non-duality of concentration and wisdom, the living concentration that is apart from marks within marks," as the conclusion of Chan's whole doctrine of concentration, is the province of this Part's later paper, and is touched here in only a single line, not borrowed forward. In a phrase: equal study and substance-and-function are Huineng's specific proposition (established here); non-duality and the living concentration are the terminus of the whole Part's doctrine of concentration (sealed there).

As for sudden-and-gradual itself — the one who gathers it up best is, of all people, that Zongmi so often taken as the spokesman for "gradual cultivation." In his Prolegomenon to the Collection of Chan Sources, Zongmi says:

The Dharma has no sudden or gradual; sudden-and-gradual lies in the capacity.²⁵

And he synthesises the sudden and the gradual into a single mutually resourcing structure — "one must first awaken suddenly, and only then may cultivate gradually … as the sun rises suddenly, frost and dew melt gradually."²⁶ The sun's rising is sudden (sudden awakening), but the melting of frost and dew is gradual (gradual cultivation); the two are not two competing attainments but two speeds of one and the same matter — the awakening in an instant, the seasoning of it in the field of phenomena coming to ripeness only over time. Zongmi says still more directly that this meaning is "to show that sudden awakening draws upon gradual cultivation."²⁷ This famous systematiser of Chan history moved sudden-and-gradual, with his own hand, from the plane of "the substance of the Dharma" to the plane of "the capacity" (the receiver of the Dharma), making the sudden and the gradual mutually resourcing rather than mutually exclusive — and this is one ancient precedent for the present paper's synthesis, that "sudden and gradual are two readings of concentration."

——

Interlocutors. Set this "non-ranking" reading within the context of modern Chan scholarship, and several approaches are worth viewing alongside it. John R. McRae exposes the "Southern-sudden, Northern-gradual" opposition as in the main a retrospective construction by Shenhui's faction, not a historical contest, and rehabilitates the Northern school's actual teaching — far subtler than the "gradual equals mirror-wiping" strawman.²⁸ This rehabilitation is exactly what the non-ranking discipline needs: to refuse to rank is to correct a known polemical distortion. McRae's work, however, operates chiefly at the level of lineage genealogy, and does not reconstruct sudden-and-gradual doctrinally as "two readings of concentration"; here the paper extends past him — the two verses and the chapter on concentration and wisdom still stand as texts articulating two relations of concentration and wisdom.

Philip B. Yampolsky shows, from text-history, that the Platform Sūtra is a layered, composite text bearing the editorial imprint of Shenhui's faction, and that the biography of Huineng is largely the elaboration of legend.²⁹ This paper grants the point in full — it does not rest on a historical Huineng who "out-versed" a historical Shenxiu. On the contrary: once historicity is bracketed, the chapter on concentration and wisdom and the two verses stand purely as a text, and the very fact that the text is layered and composite, bearing Shenhui's imprint, strengthens the non-ranking reading — for if the ranking is itself an editorial-factional overlay, then to read sudden and gradual as non-ranked complementarity is to recover the doctrine from its polemical packaging.

Bernard Faure, taking the Northern school as protagonist, rereads early Chan history and treats "sudden / gradual" as a rhetoric of legitimation ("gradual" being the name the victor pins on the loser).³⁰ "Gradual equals inferior" is the victor's verdict — a judgement that powerfully supports the present paper's non-ranking stance. Faure's analysis operates at the level of legitimation; strip away that layer of rhetoric, and what remains is still two intelligible postures of concentration (cultivating toward purity; already non-dual), which do not collide on the same plane. Beyond these, the cross-cultural survey of the sudden-and-gradual question across East Asian traditions in the volume edited by Peter N. Gregory — for instance the case of Korean Sŏn, Chinul's holding of "sudden awakening and gradual cultivation" together — is one further piece of terrain showing that sudden and gradual can coexist without being ranked.³¹

The paper's own position should be stated frankly: as far as can be seen, no Western monograph takes as its central thesis "sudden-and-gradual as two non-ranked readings of concentration, grounded in the Platform Sūtra's own 'the Dharma has no sudden or gradual; persons have sharp or dull.'" The building blocks are all to hand — the rehabilitation of Shenxiu and the Northern school in McRae and Faure; the precedent of holding-together in Gregory and Buswell; the text-internal chapter on concentration and wisdom through Yampolsky's edition — but reweaving them along the axis of concentration into this non-ranked synthesis is the paper's own structural contribution.

Sudden and gradual are not two mutually exclusive attainments but two readings of one and the same concentration — the gradual gate takes concentration as ongoing wiping; the sudden gate sees concentration as already present of itself; and Huineng's "concentration is the substance of wisdom, wisdom the function of concentration" goes further, reading concentration and wisdom as one substance-and-function rather than as two parted by sequence. The Platform Sūtra's "the Dharma has no sudden or gradual; persons have sharp or dull," Zongmi's "sudden-and-gradual lies in the capacity" — the parting falls upon the person, not upon the teaching. After Bodhidharma, Chan's re-conception of concentration has taken a further step.

Concentration is the substance of wisdom; wisdom, the function of concentration.

Cross-Reference

• From the preceding paper: SAMADHI-P22　Bodhidharma's Wall-Gazing and the Birth of Chan opened Part VII, where Bodhidharma renamed concentration a "pacifying of the mind" and set it outside the four jhānas and eight attainments (the starting point of the departure spine). The present paper takes up its lead of principle and practice, opens out the sudden and the gradual, and rewrites the relation of concentration and wisdom.
• This Part's spine: the present paper deepens the departure spine (Bodhidharma named concentration → Huineng rewrote the substance-and-function of concentration and wisdom); SAMADHI-P24　Silent Illumination and SAMADHI-P25　The Huatou set out the two Song-dynasty lines side by side (without ranking); SAMADHI-P26　The Non-Duality of Concentration and Wisdom closes this spine (the living concentration apart from marks within marks) — the doctrinal summation of "the non-duality of concentration and wisdom" belongs there, while the present paper only establishes Huineng's substance-and-function formula of "concentration-and-wisdom as equal study."
• Cross-axis reference: the scriptural sourcing of the one-practice samādhi belongs to SAMADHI-P19　Mañjuśrī's Prajñā and the One-Practice Samādhi, on the axis of mindfulness; the present paper notes it only as background and does not unfold it.
• Distant reference: the papers of Part I — the four-jhāna-and-eight-attainment architecture — form the contrasting background of Chan's departure. The volume's sealing paper, SAMADHI-P31 (concentration returning to prajñā, concentration not being ultimate), is the distant pointing of this paper's reading of suddenly awakening to the self-nature, marked here by a single line only.

Sudden and gradual are presented here as two readings of how concentration is attained, and are not ranked: the Platform Sūtra itself holds that "the Dharma has no sudden or gradual; persons have sharp or dull faculties," and the Northern school's concentration is read on its own coherent terms, not as a gradualist strawman. The body text of the verses follows the Zongbao recension; the Dunhuang variants (定惠, "let no dust be," "the Buddha-nature is ever pure," "the Dharma has no gradual or sudden") are left as the base text reads and noted. The "fixing the mind, contemplating stillness is a disease" passage is a developed form found only in the Zongbao Encounter-Circumstances chapter, not a sixth- to eighth-century record. Shenhui's Determining the True and False is cited by characterisation only (it is outside the CBETA canon); McRae, Yampolsky, Faure, and Gregory are cited by paraphrase only, for contrast, not doctrinal equation.

Sudden and gradual are not two attainments but two readings of one concentration; the lamp and its light are two in name and one in substance.

The Dunhuang recension gives Huineng's verse as two stanzas; the key line of the first is cited here. The line "the Buddha-nature is ever pure" carries a collation variant; the base text 【大】 reads 「佛性常清淨」. 「菩提本無樹，明鏡亦無臺，佛性常清淨，何處有塵埃。」 ↩

5. The Dunhuang "the Buddha-nature is ever pure" (the affirmative idiom of the tathāgatagarbha line) and the Zongbao "fundamentally there is not a single thing" (the negative idiom of emptiness) are the most famous textual variant in the history of Chan. Both are readings of the sudden gate, yet their metaphysical registers are plainly distinct and may not be flattened into a single position. ↩

6.

(early Song redaction; original ca. 8th c. CE)View on CBETA online reader ↗ reads "let no dust alight" (勿使惹塵埃). The commonly transmitted "莫使惹塵埃" is a conflation of the two recensions and is not followed here. ↩

In the Dunhuang manuscript 「慧」 is frequently written 「惠」, a difference at the level of the manuscript's graphs, not of doctrine. 「以定惠為本……定惠體一不二。即定是惠體，即惠是定用……此義即是定惠等。」 The elisions (……) follow the source. ↩

10. The same passage of the Platform Sūtra's "Concentration and Wisdom" chapter contains the section on the one-practice samādhi. The scriptural sourcing of the one-practice samādhi (ekavyūha-samādhi), Daoxin's reception and transplanting of it, and the various Chan interpretations of it belong to the axis of mindfulness, where they are treated; here it is noted only as background and not unfolded. What this paper expressly takes up is the substance-and-function relation of "concentration-and-wisdom as equal study." ↩

The line "both sudden and gradual alike set up no-thought as their principle" (頓漸皆立無念為宗) is peculiar to the Dunhuang recension, and is strong evidence for the non-ranking reading. ↩

18. The whole passage "fixing the mind and contemplating stillness is a disease, not Chan," together with "purifying one's own intent is called concentration" and "the mind-ground undisturbed — the self-nature's concentration," is found only in the Zongbao recension's Encounter-Circumstances chapter and is absent from the Dunhuang recension; it is to be cited as a developed form of the Zongbao (Yuan dynasty) text, not taken outright as the words of a Huineng of around the end of the eighth century, still less as a seventh-century record of fact. ↩

22. The observation that the terminus of the Northern school's "freedom from thought" stands not far from the import of the Southern school's "no-thought" follows McRae's reconstruction of the Northern school's teaching (cited under "Interlocutors," §VI). Further, the Treatise on Contemplating the Mind (a fragmentary manuscript, T2833《觀心論》T85, No. 2833View on CBETA online reader ↗) and the Treatise on Cutting Off Perception (the second of the Six Gates of Shaoshi, T2009《少室六門》T48, No. 2009View on CBETA online reader ↗) carry the line "the single practice of contemplating the mind subsumes all dharmas" (T2009《少室六門》T48, No. 2009View on CBETA online reader ↗, p. 0366c19), transmitted as issuing from the Northern school (Shenxiu); but this is one work under two ascriptions and divergently attributed (T2009《少室六門》T48, No. 2009View on CBETA online reader ↗ is ascribed to Bodhidharma, which scholarship doubts), and any citation must be marked "transmitted as Shenxiu / Northern school, a reconstruction," and not taken as a standalone teaching of Bodhidharma's. ↩

23. The descent of the "East Mountain Dharma Gate" is seen in the Record of the Masters and Disciples of the Laṅkā[vatāra]; the opposition-structure "Southern-sudden, Northern-gradual" and the verdict "gradual equals inferior" are largely a later (Shenhui-faction) construction. See the studies of McRae and Faure (cited under "Interlocutors," §VI). ↩

24. Shenhui's Determining the True and False about the Southern School of Bodhidharma (Huatai, 732 CE) is not included in the main Taishō canon (it is found in supplementary collections / Hu Shih's edition of the Surviving Works of the Monk Shenhui); this paper cites it only as a characterisation, with no direct quotation of its original text. Zongmi's inheritance of the language is seen in his Chart of the Master-Disciple Succession of the Chan Gate, Manji Xuzangjing no. X1225, p. 0035c11 ("the Northern school is only gradual cultivation, wholly without sudden awakening" — flagged here as inherited polemic, not endorsed). ↩
