Chan Buddhism

• 1. Introduction

  ›

  Chan Buddhism carries its name from the Sanskrit word dhyana, meaning meditation, and from there the word traveled through Chinese into Vietnamese as Thien, north into Korea as Seon, and east across the sea into Japan as Zen. But the tradition itself is far older than any of those names, and its roots reach into a tangle of Indian meditation manuals, Chinese philosophical texts, and legendary stories that historians are still trying to untangle. How did a foreign religion, once dismissed as a "barbarian variant of Taoism," become the dominant stream of Chinese Buddhism? Why did its founding figures exist more as myths than as historical men? And why did a single monk's campaign at the Imperial Court in 731 reshape how every Chan school understands its own origins? Those are the questions that animate Chan's long history -- a history the source itself admits is incomplete, because the early records no longer exist.

• 2. A Tradition Born in Translation

  ›

  An Shigao, active around 148 to 180 CE, was among the first to translate dhyana sutras into Chinese, bringing Indian meditation teachings from the Kashmiri Sarvastivadin school into a culture that had its own deeply established frameworks for understanding reality. The problem those early translators faced was immediate: Buddhist concepts had no ready Chinese equivalents. A practice called geyi, or "matching the concepts," emerged as a solution. Translators borrowed Taoist vocabulary to explain Buddhist doctrine, and the confusion that followed lasted for centuries. Buddha himself was understood by some early readers as a foreign immortal who had achieved a form of Daoist non-death. Mindfulness of the breath was read as an extension of Daoist breathing exercises. The first local converts were Daoists, who blended the newly arrived Indian meditation techniques with their own tradition of neidan, Daoist meditation.

  Kumárajiva, who lived from 334 to 413, was another critical translator in this period, rendering The Sutra on the Concentration of Sitting Meditation and numerous other texts into Chinese. These Chinese translations of Indian Yogacara meditation manuals would form the bedrock for what later became Chan technique. But the environment in which Buddhism spread was contested. As the source notes, traditionalists saw the foreign influence as threatening: "the Chinese worldview was being turned upside down." Buddhism had to compete with Daoism and Confucianism in a politically unstable era, and its survival required adaptation. What emerged was a form of practice that retained Indian meditation techniques while becoming unmistakably Chinese -- shaped by the culture's emphasis on community-oriented behavior, its preference for the mundane world over a transcendent one, and its long engagement with questions about what lies beneath the surface of appearances.

  The concept of ziran, or naturalness, passed from Daoist thought into early Chan, and figures like Sengzhao and Tao Sheng, representatives of early Chinese Buddhism, drew deeply on the Daoist keystone works of Laozi and Zhuangzi. Early Chan disciples equated, at least partially, the ineffable Tao with Buddha-nature -- and in doing so, they shifted Chan's emphasis away from abstract scriptural wisdom toward something found in everyday human life.

• 3. The Patriarch Legend

  ›

  Bodhidharma, described in Chan texts as "The Blue-Eyed Barbarian," is credited by tradition as the founding figure of Chan in China. The sources about him are few and contradictory. A text from 547 calls him a figure "from Persia." A 645 account describes him as "a Brahman monk from South India." A later account, from around 715 CE, names him "the third son of a Brahman king of South India." Some traditions link him to the Pallava king of Kanchipuram. What he taught, at least according to The Long Scroll of the Treatise on the Two Entrances and Four Practices by Tan Lin (506-574), was a path to enlightenment with two doors: the entrance of principle, which required deep faith in the shared True Nature of all sentient beings, and the entrance of practice, which included four disciplines -- accepting suffering without enmity, remaining unmoved by good fortune, releasing craving, and living in accord with the Dharma.

  Bodhidharma settled in Northern Wei China and, shortly before his death, appointed Dazu Huike as his successor, making Huike the first Chinese-born ancestral founder of Chan. The transmission from teacher to student was marked by three objects passed from Bodhidharma to Huike: a robe, a bowl, and a copy of the Lankavatara Sutra. This lineage of transmission -- Bodhidharma to Huike to Sengcan to Dayi Daoxin to Daman Hongren to Huineng -- was established by the late 8th century, largely through the influence of Huineng's student Shenhui. In later writings, the line was extended backward to include 28 Indian patriarchs before Bodhidharma, tracing the transmission from Mahakasyapa, a direct disciple of the Buddha. The Song of Enlightenment of Yongjia Xuanjue, who lived 665 to 713, puts it plainly: "Mahakasyapa was the first, leading the line of transmission; Twenty-eight Fathers followed him in the West."

  The hagiography of Bodhidharma grew as Chan's institutional power grew. By the early 8th century, when Chan was gaining prominence, a full narrative had formed around him. Historical scholarship now treats these stories carefully: the actual origins of Chan may lie in Buddhist ascetics who lived in forests and mountains, long before any lineage was imagined.

• 4. The Golden Age Masters

  ›

  The fourth patriarch, Daoxin (580-651), is credited with giving Chan its first clear institutional form. Under Daoxin and his successor, the fifth patriarch Hongren (601-674), a large, permanent community of practitioners gathered at Huangmei, ending the wandering life that had characterized Bodhidharma and Huike. Hongren taught students of various religious interests -- practitioners of the Lotus Sutra, students of Madhyamaka philosophy, specialists in monastic Vinaya -- in what was described as a "loose practice" aimed at making meditation accessible to a wider audience. This settled, community-oriented model fit better with Chinese social values than the solitary ascetic life had.

  In 701, Hongren's successor Yuquan Shenxiu (606?-706) was invited to the Imperial Court by Zhou Empress Wu Zetian, who paid him due reverence. Shenxiu represented what later polemicists would call the "Northern School," associated with a gradual path to enlightenment. After the An Lushan Rebellion of 755 to 763 weakened Tang central authority, the more radical, iconoclastic masters of the outlying regions rose to prominence. The most important of these was the Hongzhou school, founded by Mazu Daoyi (709-788). This school developed what the source describes as "shock techniques such as shouting, beating, and using irrational retorts to startle their students into realization." These methods became embedded in the popular image of the Chan master -- unpredictable, challenging, always gesturing beyond the conceptual.

  The later Tang is traditionally called Chan's "golden age." A saying captured this sense of ubiquity: "Look at the territory of the house of Tang -- the whole of it is the realm of the Chan school." The great masters of this period -- Mazu, Shitou Xiqian (c. 700-c. 790), Linji Yixuan (died 867), Xuefeng Yicun (822-908) -- were later romanticized by Song dynasty writers who looked back on them as the model Chan practitioners. What those Song writers produced was not history so much as an idealized image, one that shaped every subsequent school in East Asia.

• 5. A Campaign at the Imperial Court

  ›

  The story of Huineng (638-713) as the sixth and final patriarch is one of the most dramatic narratives in Chan literature. The Platform Sutra tells that after Hongren chose him as successor, Huineng had to flee by night to Nanhua Temple in the south to escape the jealousy of Hongren's senior disciples. Modern scholarship, however, has traced this story to its origin: it was created in the middle of the 8th century as part of a political campaign.

  The architect of that campaign was Shenhui (670-762), a disciple of Huineng. In 731, Shenhui made his move at the Imperial Court, arguing that Huineng, not Shenxiu, was the true successor of Hongren. He also invented the polemical division between a "sudden" Southern School, represented by Huineng, and a "gradual" Northern School, represented by Shenxiu. As the source notes, this was a polemical exaggeration: both schools derived from the same tradition. Shenhui's campaign succeeded. In 745, he was invited to take up residence in the Heze Temple in the capital Dongdu, modern Luoyang. He fell out of grace in 753 and went into exile. But his influence outlasted his disgrace: by 796, an imperial commission formally declared the Southern line of Chan the orthodox transmission and established Shenhui as the seventh patriarch, placing an inscription to that effect in the Shen-lung temple.

  The irony is that Shenhui himself does not appear in the Platform Sutra, the very text that elevated his teacher Huineng to legendary status. He was written out of the story. Nevertheless, every surviving Chan school traces its origin to Huineng, and the doctrine of sudden enlightenment became a standard Chan teaching -- all because of one monk's successful bid for imperial recognition. Guifeng Zongmi, the most prominent successor in Shenhui's lineage and a patriarch of both the Chan and Huayan traditions, later softened the sharp edge between sudden and gradual, arguing that sudden awakening into one's true nature still requires gradual cultivation on the path to full Buddhahood.

• 6. The Song Dynasty Consolidation

  ›

  During the Song dynasty (960-1279), Chan was mobilized by the government to help strengthen central authority, and in return it became the largest tradition in Chinese Buddhism. The romanticized image of the Tang masters -- Mazu, Linji, Caoshan, Dongshan -- was generated in this period, as Song writers looked back and produced the literature that became the canonical picture of Chan's golden age.

  The Song recognized Five Houses of Chan, or five schools based on genealogical descent. The Guiyang school traced its lineage to Guishan Lingyou (771-854) and Yangshan Huiji (813-890). The Linji school, named after Linji Yixuan (died 866), became the dominant school through support from the literati and the court. The Caodong school took its name from masters Dongshan Liangjie (807-869) and Caoshan Benji (840-901). The Yunmen school descended from Yunmen Wenyan (died 949), and the Fayan school from Fayan Wenyi (885-958). Over the course of the Song, the Guiyang, Fayan, and Yunmen schools were absorbed into the Linji.

  The gong'an system crystallized in this era. Snippets of "encounter dialogues" -- recorded exchanges between masters and students -- were collected and commented upon in texts like the Blue Cliff Record (1125) by Yuanwu, The Gateless Gate (1228) by Wumen, and the Book of Equanimity (1223) by Wansong Xingxiu of the Caodong lineage. Dahui Zonggao (1089-1163), a student of Yuanwu's, introduced the huatou practice and brought gong'an study to what the source describes as its "determinative stage." Dahui is also said to have burned the woodblocks of the Blue Cliff Record, concerned it had become a hindrance to genuine practice for his students. His contemporary Hongzhi Zhengjue (1091-1157) represented the Caodong emphasis on "silent illumination" -- sitting quietly, without the dramatic emphasis on sudden breakthrough. The tension between these two approaches, sitting and koan, ran through the Song and beyond. The Song Chan also established the Wushan system, a government network of state-controlled temples ranked by prestige, with the five main Wushan temples selected around the Southern Song capital of Lin'an, near modern-day Hangzhou.

• 7. Transmission Across Asia

  ›

  Chan did not stay within China's borders. According to traditional Vietnamese accounts, an Indian monk named Vinitaruci traveled to Vietnam in 580 after studying with Sengcan, the third patriarch of Chinese Chan, establishing what would become the Thien tradition. In Korea, Seon received its most significant impetus from the Goryeo monk Jinul (1158-1210), who established a reform movement, introduced koan practice, and founded the Songgwangsa as a new center of pure practice.

  Zen reached Japan in the 12th century. Eisai traveled to China and returned to establish a Linji lineage known in Japan as Rinzai. In 1215, Dogen journeyed to China and became a disciple of the Caodong master Rujing; after his return, Dogen established the Soto school, the Japanese branch of Caodong. Today the three main Japanese Zen schools are Soto, Rinzai, and Obaku; Soto is the largest. Rinzai subdivides into lineages affiliated with temples including Myoshin-ji, Nanzen-ji, Tenryuji, Daitoku-ji, and Tofuku-ji.

  Chan also reached Tibet during the 8th century, a period of the height of the Tibetan Empire. Chinese Chan teachers, including one named Moheyan, traveled there, and disputes arose with Indian Buddhist teachers, as illustrated by the Samye debate. Many Tibetan Chan texts have been recovered from the caves at Dunhuang, where Chan and Tantric Buddhists lived side by side, producing a degree of religious mixing that later Tibetan Buddhism would carefully disentangle. By the 10th century, Chan had mostly been absorbed or displaced by the developing Tibetan tradition. The scholar Gnubs chen Sangs rgyas ye shes, in his Lamp for the Eyes in Contemplation, codified Chan, Mahayoga, and the Great Perfection as distinct vehicles, ending the creative integration that the Dunhuang texts had represented.

  The Western encounter with Chan is often dated to 1893, when the Japanese Zen monk Soyen Shaku attended the Parliament of the World's Religions in Chicago. It was not until the late 1950s and early 1960s, however, that Westerners began pursuing serious Chan practice in significant numbers. The first Chinese master to teach Westerners in North America was Hsuan Hua, who taught in San Francisco in the early 1960s and later founded the City of Ten Thousand Buddhas, a monastery and retreat center on a 237-acre property near Ukiah, California.

• 8. Revival and Continuity

  ›

  By the end of the Qing dynasty, Chan had experienced a long decline. Its revival in the early 20th century is closely associated with Hsu Yun, a figure many Chan teachers today trace their lineage to, including Sheng Yen (1930-2009) and Hsuan Hua. Hsu Yun helped reinvigorate Chinese Chan practice at a moment when the tradition was under pressure from modernization, political upheaval, and the eventual Communist Revolution.

  Sheng Yen, founder of the Dharma Drum Mountain organization in Taiwan, published over 30 Chan texts in English. Wei Chueh (1928-2016), born in Sichuan and ordained in Taiwan, founded Lin Quan Temple in Taipei County in 1982 and became known for seven-day Chan retreats. Cheng Yen, a Buddhist nun born in 1937, founded the Tzu Chi Foundation on the 14th of May 1966 in Hualien, Taiwan, beginning with a group of thirty housewives who each donated a small amount of money daily to care for needy families. Hsing Yun (1927-2023) founded Fo Guang Shan in 1967, an international movement whose headquarters in Dashu District, Kaohsiung, is the largest Buddhist monastery in Taiwan. These four teachers are popularly called the "Four Heavenly Kings" of Taiwanese Buddhism.

  On the mainland, Chan was suppressed in the early decades of the People's Republic but has been reasserting itself since the reform and opening up of the 1970s. Bailin Monastery, ruined long before 1949, was taken over by Jing Hui in 1988, who began rebuilding it. Guanghua Monastery began a six-year restoration program in 1979 under the then 70-year-old Venerable Master Yuanzhou; in 1983, the temple became one of the Chinese Buddhism Regional Temples, and in the same year Venerable Master Yuanzhou funded the establishment of the new Fujian Buddhism Academy on the site. Chan's reach today extends from monasteries in China, Taiwan, and Hong Kong to overseas Chinese communities and Western practitioners -- a span shaped at every turn by the same combination of adaptation and continuity that carried a foreign religion into the heart of Chinese culture fifteen centuries ago.
