Sudden and Gradual

7.2 Sudden and Gradual

The story of the verse-offering under the Fifth Patriarch Hongren is one most students of the path know well: the Fifth Patriarch ordered his disciples each to offer a verse to test their insight; the senior monk Shenxiu wrote his verse on the corridor wall; the postulant Lu in the rice-pounding shed, who could not read, asked someone to write a verse for him beside it; the Fifth Patriarch summoned the postulant by night and secretly entrusted to him the robe and the Dharma—he is the man later known as the Sixth Patriarch, Huineng.

As usual, one measure of care first: this contest of verses on the corridor wall, together with the detail of the robe handed on at midnight, is the layered embellishment of the lamp histories, hard to pin down as fact. This book does not rule on which is true and which false; it reads only the two verses—for each verse speaks a way of reading concentration, and that is the concentration gate's real concern.

Two Verses, Two Concentrations

Shenxiu's verse:

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.

The mind like a bright mirror: that the mirror can reflect is the awareness the mind inherently possesses; that the mirror gathers dust is why it must be wiped clean time and again. Read this way, concentration is a sustained work of maintenance—deluded thoughts are the dust, and concentration is that unbroken wiping which keeps the mirror ever bright. It presupposes three things: one who wipes, a mirror that is wiped, and dust waiting to be wiped away.

Huineng's verse calls for one more word here. The version you know by heart comes from the Zongbao recension, current since the Yuan dynasty:

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?

But in the earliest manuscript now extant, from Dunhuang, the third line differs—it reads, "The Buddha-nature is ever pure—where could there be any dust?" Both versions are the sudden gate's reading; both take the "mirror-stand and dust" framework straight apart: where there is no tree and no stand, there is nothing called wiping. Only the tone differs: the Dunhuang text breaks the dust by affirmation—the Buddha-nature being ever pure, the dust has nowhere to be; the Zongbao text breaks the dust by negation—there being fundamentally not a single thing, the dust has nowhere to alight. One affirms, one sweeps clean; both come home to the one word "sudden": concentration is not wiped into being—concentration has, from the first, no dust that could be wiped; it is not a state awaiting achievement, but the self-nature, already complete from the first.

Set the two verses side by side: the gradual gate takes concentration as the work of wiping the bright mirror clean time and again; the sudden gate sees concentration as complete of itself from the first. This is the real content of the sudden–gradual dispute within the concentration gate—what is disputed is not two states, but the way concentration is come by.

Concentration Is the Substance of Wisdom; Wisdom Is the Function of Concentration

Huineng's real contribution does not yet lie in that verse. In the chapter on concentration and wisdom in the Platform Sūtra, he pushes the question forward from "how is concentration gained" to "what is the relation between concentration and wisdom":

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. … Do not say that concentration first issues wisdom, or wisdom first issues concentration, as two separate things.

Weigh what this passage weighs. How many times along this book's road has the sequence "first concentration, then wisdom" appeared: from the precept concentration is born, from concentration wisdom is unveiled; calm as the support of insight; the tandem running fastened after the ninth abiding. Concentration was always the ladder cultivated first, wisdom the fruit it bore. Huineng cancels this framework outright: concentration and wisdom are not two things cultivated in order; they are the substance and function of one thing—when wisdom is present, concentration is within that wisdom; when concentration is present, wisdom is within that concentration; they cannot be taken apart into a before and an after.

The simile he reaches for is so ordinary it is nearly household:

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.

The moment the lamp is lit, light and lamp are both there—no time-lag of "first the lamp, and a moment later the light." Concentration is to wisdom exactly as the lamp is to its light: in name one can tell substance from function; in fact they arise together at once, and are at root one thing.

Bodhidharma gave concentration a new name; Huineng gave concentration and wisdom a new relation. This is Chan's second reconstruction of concentration after leaving the ladder of the four jhānas.

The Dharma Has No Sudden or Gradual; Persons Have Sharp or Dull Faculties

The sudden gate and the gradual gate, reading so differently—must one of them win? The Platform Sūtra's own answer is a flat no:

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."

There is only one Dharma; what we call sudden and gradual exists because the sharp-rooted see quickly and the dull-rooted see slowly—the slow and the quick lie in the person, not in the Dharma. Elsewhere the Platform Sūtra says outright that sudden and gradual are provisional names set up for the sharp and the dull; and the Dunhuang text has one more line—"both sudden and gradual alike set up no-thought as their principle": sudden gate and gradual gate honor one and the same principle, and part only over the speed of arrival.

This line—the dividing falls on the person, not on the Dharma—the book must hold tight, because the later scheme of "Southern sudden, Northern gradual" makes it far too easy to write the gradual gate up as a strawman that knows nothing but rote wiping. The facts are far otherwise. The Northern school's own text, the Expedient Means of Birthlessness in the Mahāyāna, opens by declaring that "the mind in its essence is free of thought. Freedom from thought is buddhahood"—the mind in its essence already free of thought: this is no longer the picture of wiping dust from a mirror; and the same text writes, in so many words: "In a single thought, the purified mind suddenly transcends to the stage of buddhahood." The gradual gate, in its own voice, also speaks the sudden. And in history, Shenxiu's line was, at the end of the seventh century, the establishment orthodoxy of the Chan school: Empress Wu Zetian summoned Shenxiu to the capital and honored him highly, and the saying of that day ran, "if one would speak of cultivating the Way, there is nothing beyond the East Mountain Dharma Gate." The opposition of "Southern sudden, Northern gradual," the verdict that the gradual is the lesser—these were largely constructed in later lineage polemics, and are not the reality of the Northern school's teaching. This book sets South and North side by side, and builds no strawman.

The Sun Rises Suddenly, Frost and Dew Melt Gradually

The roundest gathering-in of sudden and gradual is Zongmi's one short sentence: "The Dharma has no sudden or gradual; sudden-and-gradual lies in the capacity." The dividing falls on the person who receives the teaching, not on the teaching itself. And he left a simile that turns sudden and gradual from opponents into two faces of one event:

As the sun rises suddenly, frost and dew melt gradually.

Sunrise is sudden—the sky brightens all at once; the melting of frost and dew is gradual—it thaws inch by inch. Awakening is in an instant; the ripening of things takes its time. The reader will recognize this structure: at the close of Part Six, the Śūraṅgama's line—"In principle, awakening is sudden; in practice, it is not removed all at once." The same truth has set, in the Chan school, into a rounder fruit: sudden and gradual are not two mutually exclusive realizations, but two speeds of one and the same sunrise.

Concentration-and-wisdom as equal study: the meaning is established. The meaning must now land on the body—land on a sitting posture, land on a huatou. Of the two great doors of Song-dynasty Chan, the Caodong door opens first.
