Chapter 8. The Chan school¶

The preceding chapters examined Tiantai's perfect interfusion of the dharmadhātu, Huayan's nonobstruction of phenomenon and phenomenon, and Faxiang's precise classifications. All are highly systematic philosophical undertakings. Chan comes from another direction. It dismantles systems rather than building them. It brings concepts to rest in the present rather than accumulating them. It points directly to the Buddhadharma itself rather than explaining it.

"A separate transmission outside the teachings; not founded on words and letters; pointing directly to the human mind; seeing one's nature and becoming a buddha" is Chan's four-part account of itself. It deliberately distances itself from all writing, doctrine, and system, claiming that true Dharma transmission occurs only in a direct encounter of mind with mind between patriarch and student. The paradox is that Chan subsequently produced the largest and most diverse body of literature in Chinese Buddhism. Its recorded sayings and koans, verses on old cases and evaluative commentaries, themselves became the most important tools of Chan "Dharma transmission."

The chapter examines Chan's history and thought, and what this paradox means.

1. Bodhidharma and the legends of early Chan¶

Bodhidharma

Chan's founding legends center on Bodhidharma, known in Chinese as Putidamo or Damo. He was a real historical person, one of the many Buddhist monks who came to China at the time, arriving from India or Central Asia around the late fifth or early sixth century.

The most famous legend about Bodhidharma is his conversation with Emperor Wu of Liang (r. 502–549). The emperor asked, "Throughout my life I have built monasteries, ordained monks, given alms, and made offerings. What merit have I earned?" Bodhidharma answered, "No merit." The emperor asked, "What is the highest meaning of the noble truth?" Bodhidharma answered, "Vast openness, nothing holy." The emperor asked, "Who faces me?" Bodhidharma answered, "I do not know." Bodhidharma then departed, crossed the river northward, and spent "nine years facing a wall" at Shaolin Monastery on Mount Song.¹

Another famous legend tells how the second patriarch, Huike (487–593), stood all night in the snow seeking the Dharma from Bodhidharma, who ignored him. Huike cut off his own left arm and presented it. Bodhidharma asked, "What do you seek?" Huike answered, "My mind is not at peace. I beg you, Master, to set it at peace." Bodhidharma replied, "Bring me your mind, and I will set it at peace." After a moment's silence, Huike answered, "I have searched for my mind and cannot find it at all." Bodhidharma said, "I have finished setting your mind at peace."

Modern scholars generally reserve judgment on the historical truth of these two legends. Accounts of Bodhidharma meeting Emperor Wu appear very late, and the story of Huike severing his arm grew progressively richer through successive textual layers. Yet they clearly convey the central Chan spirit. Search for the mind, and it cannot be found; setting the mind at peace means knowing that it cannot be found.

The historical Bodhidharma

What can be documented is Bodhidharma's close relationship with the Laṅkāvatāra Sūtra. He was called a "Laṅkāvatāra master," and early Chan took this sūtra as its principal scriptural basis. Its central themes are the relation between tathāgatagarbha and ālayavijñāna, already noted in Chapter 7.1, and the analysis of the various levels of consciousness. Early Chan was thus doctrinally close to the tradition of Yogācāra and tathāgatagarbha; it was not an "antitraditional" movement that appeared from nowhere.

The most reliable work attributed to Bodhidharma is the Treatise on the Two Entrances and Four Practices. It sets out "entrance through principle," seeing the inherent nature of suchness through meditation, and "entrance through practice." The latter comprises four approaches through conduct: accepting retribution for wrongs, following conditions, seeking nothing, and acting in accord with the Dharma. The framework is relatively simple and far less dramatic than later Chan legends, but it is closer to the historical Bodhidharma.¹

2. From the first to the sixth patriarch: Chan genealogy¶

The traditional Chan genealogy lists six generations of patriarchs from Bodhidharma to Huineng.

The first two lines of Sengcan's Inscription on Faith in Mind read, "The utmost Way is without difficulty; it only shuns picking and choosing." Not choosing and not discriminating became central themes of practice throughout subsequent Chan.

Daoxin established a meditation community of several hundred people on Mount Shuangfeng in Huangmei, Hubei. This marked a decisive turn from individual, itinerant Dharma transmission to an organized community. His disciple Hongren further developed it into the "East Mountain Teaching," with more than a thousand disciples at its height. They included Shenxiu (c. 606–706) and Huineng (638–713), who would later stand at the head of the separate Northern and Southern schools.

3. Huineng and the Southern school: the establishment of sudden awakening¶

The section begins with history, then turns to texts. The legend of Huineng and the historical process by which he was established as the sixth patriarch are different matters.

Shenhui: an organizer of the campaign, not a spectator

After Huineng's (638–713) death, his place in Chan history did not immediately gain general recognition. During his lifetime and for a time afterward, the title of "Chan orthodoxy" in fact belonged to another figure, Shenxiu (c. 606–706). Invited to Luoyang by Wu Zetian and honored in succession by two emperors, Zetian and Zhongzong, Shenxiu was the most prominent Chan master of the time in both political and religious terms. His following far surpassed Huineng's lineage. His historical position bore no resemblance to the later narrative's placement of "gradual cultivation below sudden awakening."

The situation changed through a long-planned polemical campaign organized by Huineng's disciple Shenhui (684–758).²

Around 732, Shenhui presided over a public debate at Dayun Monastery in Huatai, in present-day Henan, known as the "Huatai Dharma Controversy" or "Huatai Assembly." His central argument was that Hongren had passed the transmission of the true Dharma, through the robe and bowl, to Huineng rather than Shenxiu. The Northern school, Shenxiu's disciples, was a collateral branch without orthodox standing; the Southern school was the true transmission, and Huineng the sixth patriarch. He also explicitly labeled the Northern school "gradual cultivation," opposing it to the Southern school's "sudden awakening" and elevating a difference between styles of practice into a contest between orthodoxy and heresy.

The debate provoked a powerful response. Shenhui took up residence at Heze Monastery in Luoyang in 745. In 753, the twelfth year of Tianbao, he was impeached and banished on the charge of "gathering a crowd," moving among Yiyang, Wudang, Xiangzhou, Jingzhou, and other places. The political situation changed during the An Lushan rebellion (755–763). Shenhui rendered meritorious service by helping the authorities sell ordination certificates, proof of monastic registration, to fund the military. He was allowed to return to Luoyang and resume teaching at Heze Monastery. His reputation grew greatly in his later years, and he attracted many disciples. It was precisely in this period that the narrative of "the orthodox Southern school and collateral Northern branch" began to become firmly established more widely.³

Huineng's recognition as sixth patriarch: a century after his death

Huineng died in 713. His formal recognition as "sixth patriarch" at the imperial level came about a hundred years after his death. Under Emperor Xianzong of Tang (r. 806–820), the court gave him the posthumous title "Chan Master Dajian" and recognized his disciples at Caoxi in Guangdong as Chan's direct lineage. The entire establishment of "sixth-patriarch orthodoxy" was a multistep process, from Shenhui's campaign outside official circles, through local acceptance, to court recognition. It took decades and spanned two emperors; it certainly did not emerge naturally during Huineng's lifetime.

The Huineng written into history as an "illiterate firewood seller" whose single verse surpassed all the monks became the "orthodox sixth patriarch" through a carefully constructed campaign. That campaign truly began only after his death, and was completed nearly a century later.

The text of the Platform Sūtra: from Dunhuang to Zongbao

The Platform Sūtra of the Sixth Patriarch was neither written by Huineng himself nor composed at a single definite moment. Its text evolved from a relatively simple form into an increasingly elaborate one. The surviving versions can be arranged chronologically as follows.

The Dunhuang manuscript is the key to understanding the historical origins of the Platform Sūtra. In 1900, the Daoist priest Wang Yuanlu discovered a large collection of manuscripts that had been sealed for about a thousand years in Cave 17, the Library Cave, at the Mogao Caves in Dunhuang, Gansu. They included an early copy of the Platform Sūtra. The Dunhuang text differs markedly from the Zongbao version commonly used today. Even the wording of the two famous verses differs. In the Dunhuang manuscript, Huineng's verse reads: "Bodhi originally has no tree; the bright mirror likewise has no stand; buddha-nature is always pure; where could there be dust?" The common version instead reads: "Nor is the bright mirror a stand… Originally there is not a single thing; where could dust alight?" Moreover, in the Dunhuang text Huineng composes two verses in succession. The second is: "The mind is the bodhi tree; the body is the bright mirror's stand; the bright mirror is originally pure; where could dust stain it?" This differs from the familiar story in which a single verse decides the contest, and the account of Dharma transmission is also more abbreviated.⁴

The differences show that the Platform Sūtra is not a faithful record of a historical occasion. It is a text continuously revised, enriched, and perfected over several centuries. Its process of "taking shape" ran alongside the Southern school's gradual acquisition of orthodox status.

The two verses and the core of the myth

The famous verse contest in the Platform Sūtra remains Chan's best-known narrative core. It pits Shenxiu's "diligently wipe it clean at all times" against Huineng's "originally there is not a single thing." Whatever its historical truth, it succinctly expresses the philosophical substance of the controversy over sudden and gradual awakening.

Shenxiu's verse represents gradual cultivation. The mind is like a mirror that can be stained by dust, or afflictions, and must be wiped clean constantly.

Huineng's verse represents sudden awakening. There is no substantial "mirror of mind" that needs wiping, nor any "dust" that can stain the originally pure nature of awakening. Directly knowing this is awakening.

This book's position

This book's position is that the Platform Sūtra has no ground on which to stand as historical fact. Huineng may have existed, but the episodes in the Platform Sūtra are products of the Southern school's narrative project. The illiterate firewood seller surpasses all the worthies with one verse; Hongren secretly transmits the robe and bowl at night; Huineng flees Lingnan and spends years avoiding persecution. The episodes have no corroboration in historical documents, and their textual sources accumulated in layers over centuries. The Dunhuang manuscript already reveals enormous differences between the early and common versions, demonstrating that this "sūtra" underwent continuous mythologization and supplementation as it took shape.

The Platform Sūtra still has value, on two levels outside history.

First, it is a narrative archive of the struggle between the Northern and Southern schools. Shenhui's campaign needed a narrative to support its claim to "orthodoxy," and the Platform Sūtra supplied it. Through literature, it established "sudden awakening is superior to gradual cultivation" and "the robe and bowl were transmitted to the Southern school" as self-evident truths. It reflects how monastic communities of that era used narrative to settle questions of authority.

Second, it shaped the basic direction of all subsequent Chinese Chan. Whether or not the Platform Sūtra accurately reflects history, its framework of questions, encompassing sudden awakening and seeing one's nature, no-thought and not relying on words and letters, defined Chan's self-understanding for the following thousand years. The later Linji and Caodong schools, and indeed every tradition bearing the name "Chan" or "Zen" today, unfold within the imaginative space it delineated. In terms of its history of influence, it is a decisive text.

4. The philosophical content of the Platform Sūtra¶

The philosophy of the Platform Sūtra centers on several concepts.

No-thought

No-thought is the Platform Sūtra's central concept of practice. It means "no attachment while thinking," rather than "thinking nothing at all," which would be psychological suppression. When thoughts arise, do not grasp them, follow them, or reject them. Thoughts come and go; the mind is like flowing water, leaving no trace.

The Platform Sūtra says, "No-thought as the guiding principle, no-form as the essence, nonabiding as the basis." The three negations form the three main principles of Southern Chan practice.

No-form. Do not establish grasping upon the characteristics of external objects. It does not assert that external objects do not exist; it asks only that one not generate discriminative characteristics in relation to them.

Nonabiding. Do not remain in any thought or state. The nature of mind is flowing; "abiding" itself is attachment.

Seeing one's nature and becoming a buddha (Seeing One's Nature = Becoming Buddha)

Chan's theory of liberation centers on "seeing one's nature." "Nature" is buddha-nature, the nature of awakening that everyone originally possesses. "Seeing" is recognizing what has been there all along, rather than "acquiring" something new by accumulating merit or studying sūtras and treatises. It has always been there, merely obscured by deluded thoughts and unrecognized.

The position comes from the tathāgatagarbha tradition, which holds that "the nature of mind is originally pure; afflictions are adventitious dust" (Chapter 7.1). Chan pushes it to an extreme. Even the act of "practice," if undertaken with the attitude "I am practicing in order to become a buddha," is already an attachment, an estrangement from buddha-nature. True practice is to be unattached, nondiscriminating, and responsive to conditions in every present moment.

The Platform Sūtra says, "When one's own nature is deluded, the buddha is a sentient being; when one's own nature awakens, the sentient being is a buddha." The buddha and I share one nature; the difference lies in delusion and awakening.

Chan's theory of liberation and early Buddhism's: a necessary comparison

One matter needs to be made clear here, because the misunderstanding is so widespread.

Many people hear that "early Buddhism had meditation practices" and immediately think of Chan. They think of sitting quietly and critical phrases, of seeing one's nature and "pointing directly to the human mind." The association is understandable. Chan's name derives literally from channa, the Chinese transcription of Sanskrit dhyāna, Pāli jhāna, and early Buddhism certainly practiced jhāna. Yet this etymological connection obscures fundamental differences in goals of practice, philosophical presuppositions, and practical methods.⁵

1. Early Buddhism's theory of liberation

Early Buddhism's theory of liberation has the Four Noble Truths as its structure: suffering, its origin, its cessation, and the path, as discussed in detail in 1.5. The root of suffering is craving (taṇhā); the way is the Noble Eightfold Path; the goal is the complete cessation of craving and the ending of suffering. The framework is diagnostic and therapeutic. Practice is a tool, and the goal can be described as the extinguishing of afflictions and no further birth.

In early Buddhism, jhāna, the four absorptions, is a specific stage on the path of practice, rather than the goal itself. It has precise signs of entry: in the first jhāna, initial and sustained application of thought; in the second, their calming and inner clarity; in the third, the fading of joy and abiding in equanimity; in the fourth, purity of equanimity and mindfulness. Its function is to cultivate concentration and provide a stable epistemological basis for insight (vipassanā). Supported by concentration, practitioners observe the five aggregates through the three characteristics of impermanence, suffering, and not-self. Grasping dissolves, craving ceases, and the fruit is realized.

Several things never appear in this framework. There is no "buddha-nature" (buddhadhātu) awaiting recognition, no presupposition that one "is already a buddha," and no possibility of complete liberation through a single act of "seeing one's nature." Liberation is a process with describable stages. Stream-entry, once-returning, nonreturning, and arhatship each involve the severing of corresponding fetters. Nibbāna itself is expressed in negative language: the cessation of craving, the ending of suffering, no further saṃsāra. The emphasis is on "what has ceased," rather than "what has been recognized."

2. Chan's theory of liberation

Chan's theory of liberation has an entirely different structure. Its basic presupposition comes from the tathāgatagarbha tradition (see Essay 7). All sentient beings are originally buddhas; buddha-nature has never been lost, only obscured by deluded thoughts and unrecognized. Liberation, or awakening, is therefore an act of recognition, recognizing what was there all along, rather than acquiring something new through accumulated merit or systematic practice.

Chan's methods consequently differ in character from early Buddhism's systematic cultivation. They do not accumulate through the sequence "ethical discipline → concentration → wisdom." Instead, at a particular moment, a teacher's guidance, the pressure of a koan, or a direct encounter in everyday activity breaks through the overlay of concepts, immediately revealing one's nature. It can happen at any time ("the Way is in everyday activity"), without first entering a particular state of meditative absorption.

Chan's "seated meditation" is likewise not "entering jhāna" in the early Buddhist sense. It is closer to allowing the nature of awakening to manifest naturally, without conceptual operations, while the body is still. Hongzhi's silent illumination Chan follows this direction; Dahui's critical-phrase contemplation Chan uses a critical phrase to concentrate attention and create the conditions for a breakthrough. Both differ sharply from early Buddhism's systematic cultivation through the sequence of four jhānas.

3. Structural comparison

4. Why the two are often confused

The immediate cause of confusion is the word chan. Chan's name derives from dhyāna, leading people to suppose that Chan is the Chinese transmission of early Buddhist jhāna practice. Yet in the Chan context, the word has been substantively redefined. It shifts from entering a particular state of absorption to abiding in a state of "the nature of awakening manifesting in the present." The name is the same, but its content has drifted considerably.

The deeper difference lies in ontological premises. Early Buddhism does not recognize a "buddha-nature" as a positive basis of existence; Chan's entire construction depends on the tathāgatagarbha presupposition that "nature is pure and everyone possesses it fully." The difference goes beyond one in method to a difference in "what the question itself is." Early Buddhism asks "How does suffering cease?" Chan asks "How is one's nature recognized?" Both questions are real, and the answers they yield naturally point in different directions.

This book holds that treating Chan's "seated meditation and seeing one's nature" as a continuation of early Buddhist jhāna practice is a double misreading, historical and philosophical. Both deserve serious consideration, but the prerequisite is to distinguish them first.

5. Tang Chan in full flowering: Mazu and Shitou¶

After Huineng, Chan entered a period of extraordinary creativity in the mid-Tang.

Mazu Daoyi (709–788)

Mazu Daoyi was Huineng's Dharma-grandson (Huineng → Nanyue Huairang → Mazu Daoyi). His teaching style moved Chan from relatively introspective seated meditation toward breakthrough dialogues in everyday life.

His famous teaching was "this very mind is buddha." Later, he also taught "neither mind nor buddha" to break students' attachment to the earlier teaching.

Mazu's method of transmission began to make extensive use of shouts and blows to break students' conceptual frameworks and habitual patterns. The style of teaching anticipated the later Linji school.

Shitou Xiqian (700–790)

Shitou Xiqian was Mazu's contemporary but differed greatly in style. Mazu represented a Chan of "doing" and "direct action"; Shitou a Chan of "suchness" and "perfect interfusion." His famous poems, Song of the Grass Hut and Harmony of Difference and Sameness, describe a natural Chan in which "grasses and trees, mountains and rivers are all the work of buddhas." The close connections with Daoism and Huayan are visible here.

6. The five houses and seven schools¶

Extending from the two lines of Mazu and Shitou, Chan developed five principal houses, or lineages, from the late Tang and Five Dynasties through the early Northern Song.

After the Song, only Linji and Caodong ultimately remained of the five houses. They are still East Asia's principal Chan transmissions today.

Linji Yixuan (?–866)

Linji Yixuan was one of the most forceful teachers in Chan history. His "three mysteries and three essentials" formed an analytical framework for teaching that kept students from remaining at any single level. He also taught the famous "true person of no rank," shouting at students: "You cannot tell good from bad! Look at that true person of no rank!" The "true person of no rank" is "this" that sees, hears, and thinks at every moment. It has no fixed position and cannot be confined within concepts, yet is always present.

7. The development of the koan system¶

Origins of the koan (Chinese gong'an, Japanese kōan)

"Gong'an" was originally a Song legal term meaning a public record or legal precedent. Chan borrowed it to designate "cases already adjudicated by the patriarchs." They record exemplary dialogues between patriarchs and students for later students to investigate.

According to Chan's own account, the function of a koan is not to be "solved" through intellectual analysis. It concentrates a student's entire attention on a point that concepts cannot resolve, until the conceptual framework collapses and, at that moment, the student directly sees their nature.⁶ The account is contested in scholarship, and one line of objection comes from within the tradition. The Rinzai monk and scholar G. Victor Sōgen Hori argues that the Rinzai kōan curriculum does contain articulable doctrinal content, and that seeing one's nature occurs within ordinary thought and language, rather than in a separate realm without thought.⁷ Dale S. Wright goes further, arguing that Chan's "immediacy" is itself constituted by language and rhetoric.⁸

The three major koan collections

Zhaozhou's "Mu"

The first case of the Gateless Barrier is the most famous koan.

"A monk asked Zhaozhou, 'Does a dog have buddha-nature or not?' Zhaozhou said, 'No.'"

According to the sūtras and treatises, Buddhism explicitly states that "all sentient beings have buddha-nature," so Zhaozhou should have said "yes." Yet he said "no." Students are instructed to concentrate all their attention on "this 'no'" (wu in Chinese, mu in Japanese) rather than intellectually considering why Zhaozhou said it. They let this "no" fill their entire consciousness until all discrimination and inference stop, and the word itself silently discloses something.

8. Song Chan: critical-phrase contemplation and silent illumination¶

In the Song, Chan underwent a second major division, chiefly expressed in the controversy between the Linji school's critical-phrase contemplation and the Caodong school's silent illumination.

Critical-phrase contemplation Chan (Kanhua Chan; Dahui Zonggao, 1089–1163)

Dahui Zonggao systematized koan practice around concentration on the huatou, or critical phrase, in a case. Usually this is its most meaningless phrase, the one least amenable to a logical solution. Students focus all their energy on it day and night until a breakthrough occurs.¹

Dahui emphasized the "great feeling of doubt." True practice requires a deep sense of perplexity before the critical phrase, like "a hot iron ball stuck in the throat, impossible to swallow or spit out." Only when this feeling of doubt accumulates to its utmost can a real breakthrough occur.

Silent illumination Chan (Mozhao Chan; Hongzhi Zhengjue, 1091–1157)

Hongzhi Zhengjue's approach combines "silence," allowing the mind to become still, with "illumination," maintaining clear awareness. It requires no concentration on a particular critical phrase. One simply abides in open, objectless awareness, allowing all dharmas to appear as they are, without grasping or rejection.

Dahui criticized silent illumination as "the perverse Chan of silent illumination." Without the support of a critical phrase, he argued, it easily lapses into "dead sitting," lacking the power of breakthrough. Hongzhi countered that Dahui's critical-phrase contemplation was too tense and lacked "serenity," holding that true practice should be natural and uncontrived.

The controversy touches a real philosophical question. Does awakening come through "doing," requiring concentration and breakthrough, or through "letting go," requiring relaxation and release? The controversy has continued throughout East Asian Chan history, with a similar tension between Japan's Rinzai and Sōtō schools.

9. Chan's intellectual sources¶

Chan claims "a separate transmission outside the teachings," yet in fact rests deeply on several Indian and Chinese intellectual traditions.

Tathāgatagarbha and buddha-nature. Chan's "seeing one's nature and becoming a buddha" comes directly from the tathāgatagarbha tradition. Nature is pure; all sentient beings have buddha-nature; awakening is seeing this nature, rather than acquiring something new (Chapter 7.1). Without the tathāgatagarbha tradition, Chan's central claim would have no ground on which to stand.

The Vimalakīrti Sūtra and Diamond Sūtra. These are the texts Chan quotes most often, in Kumārajīva's translations, as noted in Chapter 10.3. Vimalakīrti's "silence," a silence like thunder, entering the Dharma-gate of nonduality, is Chan's prototype for "the path of speech cut off." The Diamond Sūtra's injunction to "give rise to a mind that abides nowhere" is the scriptural source of "nonabiding" and the basis of Huineng's awakening.

Daoism and the Learning of the Mysterious. Chan's language of nature, "bamboo is green, flowers are red," its position that "ordinary mind is the Way," and its emphasis on "nonaction" and "naturalness" all have a Daoist coloring, an inheritance from the age of geyi discussed in Chapter 10.2. Mazu's "hungry, eat; tired, sleep," offered as the highest expression of Chan insight, has an inner resonance with Daoist "naturalness."

The Three Treatise school and Sengzhao. The Three Treatise school's understanding of emptiness, that everything is empty with nothing to grasp, and Sengzhao's description of "no-knowing" as the state of prajñā in Prajñā Has No Knowing both supplied intellectual support for Chan's "no-thought and no-form."

10. The spread of Chan¶

Transmission to Korea

Chan entered Korea in the ninth century, giving rise to the "Nine Mountain Seon Schools" during the Silla and Goryeo periods. Jinul (1158–1210), the most important synthetic thinker in Korean Seon history, sought to combine Seon with doctrinal teaching, specifically Hwaeom. The Jogye Order, still South Korea's largest Buddhist denomination, belongs to the Seon tradition.

Transmission to Vietnam

The principal lineages of Vietnamese Thiền are largely connected with Chinese Chan. Wuyantong, known as Vô Ngôn Thông, brought the Linji lineage to Vietnam in the ninth century. Thiền remains an important part of Vietnamese Buddhism today.

Transmission to Japan

Eisai (1141–1215) traveled twice to Song China and brought Linji, or Rinzai, back to Japan, where it received enthusiastic support from the warrior class under the Kamakura shogunate. Dōgen (1200–1253) traveled to Song China and received the Dharma from the Caodong master Tiantong Rujing. He brought Caodong, or Sōtō, back to Japan and wrote the Shōbōgenzō (Treasury of the True Dharma Eye), one of the most important philosophical works in Japanese Buddhist history.⁹

As a cultural phenomenon, Japanese Zen spread widely in the West during the twentieth century through the writings of D. T. Suzuki.

11. This book's philosophical assessment¶

Chan is Chinese Buddhism's most original philosophical achievement. It reduces the complex conceptual systems of the entire Indian Buddhist tradition (the eight consciousnesses, three natures, three truths, four dharmadhātus, and so on) to one question: where are you? What is this seeing, this hearing, this active consciousness at this moment? Chan's originality lies in finding a way to turn this question into a practice through koans, critical phrases, and moments of Chan insight in everyday life. It no longer remains merely a philosophical topic.

Whether sudden awakening is possible is a real philosophical question. The tathāgatagarbha tradition says that nature is originally pure and awakening is the recognition of this fact. Chan pushes the claim to an extreme, saying that this recognition can occur in an instant without any preparation. At the Lhasa debate (Chapter 8.3), Kamalaśīla criticized this position, arguing that without correct conceptual understanding as a foundation, any "sudden awakening" is only a psychological blank, not yet genuine awakening. Chan replies that Kamalaśīla has made "correct conceptual understanding" a necessary intermediate step, but that this step itself is attachment. The debate remains unfinished. This book does not adjudicate it, but points out that it is a real philosophical controversy, which cannot be regarded as settled simply because Chan achieved an overwhelming cultural victory in China.

The tension between Chan's "not relying on words and letters" and its literary tradition is a creative contradiction. Works such as the Blue Cliff Record and the Gateless Barrier contain some of the most exquisite prose in world literature. The realms they describe, where "the path of speech is cut off," are conveyed precisely through these words. The contradiction does not amount to Chan's failure; it is the site of Chan's philosophical tension. Language cannot convey awakening directly, but it can bring readers to the edge where language ceases. There, something different may happen.

Whether Chan truly is "a separate transmission outside the teachings" is open to doubt. It rests deeply on the intellectual resources of tathāgatagarbha, the Three Treatise school, Huayan, and Daoism, merely concealing these sources within a narrative framework of "patriarchal transmission." Knowing these sources helps us understand Chan's place in Chinese intellectual history and assess how "unique" its philosophical claims actually are.

Several structural problems in Chan

The section specifically raises several critical observations that deserve to be faced. It does not intend to deny Chan's value as a tradition, but to assess its philosophical claims honestly.

First: a path to liberation without actual practice?

Chan's theory of sudden awakening has repeatedly produced a practical danger in history. It is easily understood to mean that epistemological "understanding" is already liberation, as though "my nature was originally buddha; now I recognize it, and that is the end of the matter." The understanding differs greatly from early Buddhism's theory of liberation, which requires the complete severing of afflictions and fetters and has explicit markers of attainment. It is also far removed from the Mahāyāna theory of practice, which requires cultivation over countless eons. The misunderstanding has recurred throughout history. People say "I have seen my nature" while remaining full of greed, aversion, and delusion in their behavior; others claim there are "no precepts to observe," because inherent nature itself is the precepts, and indulge themselves. Chan's own koan literature preserves a specimen: Nanquan kills the cat. The monks of the east and west halls were quarrelling over a cat. Nanquan Puyuan held it up and said that if anyone could say a word he would spare it, and if not he would cut it down; no one answered, and he cut the cat in two. When Zhaozhou came back that evening and heard of it, he took off a straw sandal, set it on his head, and walked out. Nanquan said that had Zhaozhou been there, the cat would have been saved.¹⁰ Whether or not it happened, what matters is where the tradition placed the story. The Jingde Record of the Transmission of the Lamp puts it in Nanquan's own biography; the Gateless Barrier makes it Case 14; the Blue Cliff Record splits it into Cases 63 and 64. Wumen's comment asks only what Zhaozhou meant by the sandal on his head, and Yuanwu's note on the killing reads "Splendid, splendid! Anyone who would not do this is a fellow kneading lumps of mud." None of the three records or their commentaries treats the killing as a fault. Yuanwu adds that "in truth he did not cut at the time, and the story does not turn on cutting or not cutting," which removes the killing itself from the discussion. A patriarch kills a living being with his own hand to make a point, and the tradition files it not as a lapse but as a model for contemplation. Dahui Zonggao in the Song saw the danger here. Of Guizong cutting the snake and Nanquan cutting the cat, he wrote that "those who learn by rote mostly call it the marvelous function that meets the occasion, or the great function manifesting without keeping to any rule; they do not know that it is nothing of the kind." The sentence establishes two things at once: reading the cat story as "the great function manifesting without keeping to any rule" really was a current reading within Chan, and by the Song it was already being condemned by Dahui as the error of rote learners. Section 11.4 observes that Chan and tantra share a structural risk over what grounds the precepts after awakening; Chan's most famous instance is here.

Second: what follows "awakening is only the first step"?

A common response in contemporary Chan circles to the criticism that "sudden awakening is not liberation" is that awakening (seeing one's nature, initial awakening) is only the first step. Prolonged practice is still needed to deepen, stabilize, and embody it. The account has historical grounds. The Korean Seon master Jinul (1158–1210) proposed "sudden awakening followed by gradual cultivation," and the Japanese Rinzai kōan system, in which practitioners continue investigating a series of cases after seeing their nature, has a similar framework.

Yet this response leaves a question that has still not been adequately answered. What is the content of this "practice after awakening"? What are its standards? How does it know that it is progressing rather than going in circles? Early Buddhism's system offers relatively clear answers in the sequence of four fruits and the severing of the ten fetters. By contrast, descriptions of "Chan practice after awakening" are quite vague in most traditions. Sometimes they borrow tools from other traditions, such as Theravāda insight meditation or psychotherapy; sometimes they appeal to "spontaneous functioning in life," following conditions and taking everyday activity as the Way; sometimes they simply continue investigating koans. All have value. Whether they constitute a testable, traceable path to liberation, however, remains a real open question.

Third: Chan as ritual and performance

English-language Chan scholarship in recent decades has offered a critical analysis from within. Robert Sharf and other scholars argue that many Chan behaviors called "expressions of awakening" may be better understood as ritual performances, rather than spontaneous expressions of a state of liberation. They include blows and shouts, encounter dialogues, silent responses, and displays of "Chan spirit" in everyday conduct. The behaviors are scripts learned and prescribed within Chan institutions. Delivering a blow, shouting, or smashing a teacup on the floor derives its meaning from the interpretive framework the institution gives it, not necessarily from the actor's inner state of liberation. The limits here must be marked. The two scholars discuss only encounter dialogues and koans. Blows and shouts, silent responses, and displays of "Chan spirit" in everyday conduct are this book's extensions of the same reasoning to three further categories.¹¹

Bernard Faure offers a related analysis. Chan constructs a rhetoric of "immediacy," claiming that its Dharma transmission bypasses all mediation, passing directly from mind to mind. Yet that rhetoric is itself a highly cultural and institutional construction; it does not amount to genuine "absence of mediation."¹²

The analysis does not deny real practice or inner transformation within Chan. It questions the external signs used to judge "whether someone has awakened", such as the ability to respond nimbly in encounter dialogue or to display a "Chan manner." These signs very likely measure primarily a person's mastery of Chan's narrative style and institutional culture; they have difficulty measuring the extent of inner liberation.

Fourth: an intellectual game for clever people?

Taken together, these points raise an uncomfortable question. Have some forms of Chan become an intellectual game for clever people? One can use paradoxical language fluently, turn conventional logic back and forth, and display the nimbleness of "nonabiding" in koan exchanges. How close to, or far from, the substance of liberation are these skills?

This book has no answer, but regards this as a real question that should not be obscured by Chan's literary charm and cultural prestige. Alongside its abundant works of literary and intellectual genius, historical Chan produced many people who claimed to have "illuminated the mind and seen their nature" yet showed no change in behavior or character. The problem goes beyond individual failures of practice; it is systematic and structural. When the standards of judgment rest on "performance" and "verbal display," rather than testable changes in body and mind, the system lacks a mechanism for correcting itself.

Early Buddhist stream-entry has clear criteria: unshakable confidence in the Three Jewels, unbroken observance of the five precepts, a certain foundation in meditative concentration, and understanding of the Dharma. The criteria can be indirectly verified through behavior and statements. Chan's "seeing one's nature" has no corresponding externally testable standard; it entrusts judgment entirely to recognition mechanisms within the lineage. Institutionally, this plants the risks described above.
