The Chinese reception
When Mahāyāna Buddhist texts and practitioners began arriving in China along the Silk Road in the first centuries CE, they encountered a host culture that already possessed an articulated contemplative vocabulary — the Taoist tradition of Lao Tzu and Zhuangzi, with its emphasis on the Tao as the unnameable ground, *wu wei* as the operative mode of accord with it, and the cultivated naturalness of the realised practitioner as its sign. The translators of the first Chinese Buddhist canon worked with this vocabulary at hand. Sanskrit bodhi was rendered through Chinese characters that the Taoist literature had already loaded; dharma was sometimes rendered as Tao; nirvāṇa was approached through Taoist words for nothingness and non-action. The hybrid that resulted by the fifth and sixth centuries was no longer recognisably Indian Mahāyāna and not quite Chinese Taoism; the new thing that emerged was the school the Chinese began calling Chán, after the meditation (Sanskrit dhyāna) the school took as its operative method. The four-line motto the tradition retrospectively credited to Bodhidharma — almost certainly composed in the eighth or ninth century rather than the sixth — was the school's compressed self-description: a transmission of recognition mind-to-mind that did not depend on the textual apparatus the older Chinese Buddhist schools had built up around translation and commentary.
Patriarchs, schools, the Southern turn
The lineage chart the Chan tradition stabilised by the late Tang treats Bodhidharma (semi-legendary, traditionally arriving from south India in the early sixth century) as the first patriarch, with five succeeding Chinese patriarchs leading down to Huineng (638–713), the sixth and last, after whom the lineage of single succession was treated as having split into the five houses of mature Chan. The most consequential single event in the school's self-formation was the late-eighth-century Southern turn — the polemical promotion of Huineng's sudden awakening line over the rival Northern school of Shenxiu, the head monk whose verse Huineng's poem-reply famously surpassed in the Platform Sūtra contest. The five houses that emerged from the Southern lineage — Linji, Caodong, Yunmen, Fayan and Guiyang — produced the contemplative literature on which the school's later international reputation rests: the gōng'àn (*kōan*) collections of the Blue Cliff Record and the Gateless Gate, the dialogue records of figures like Linji Yixuan, Mazu Daoyi and Zhaozhou Congshen, the Caodong line's signature just sitting (zhǐguǎn dǎzuò, later Japanese *shikantaza*) under Dongshan Liangjie and Hongzhi Zhengjue. The transmission to Japan in the twelfth and thirteenth centuries — Eisai carrying the Linji line as Japanese Rinzai, Dōgen carrying the Caodong line as Sōtō — is the channel through which what the Anglophone reader encounters as Zen reached the West.
Where to encounter the tradition in the index
Alan Watts's *The Way of Zen* is the index's most extensive single account of the Chinese half of the Chan-and-Zen lineage. The book devotes its first half to the Chinese background — Taoism, the early translators, the patriarchal lineage, the Southern–Northern split — before turning to the Japanese reception, and is the closest thing to a working historical introduction in English that an interested reader is likely to need. D. T. Suzuki is the other twentieth-century English-language voice through whom the Chinese material reached Western readers; his early-century essays draw extensively on the Tang patriarchal records and the Song-dynasty kōan collections. Shunryu Suzuki's *Zen Mind, Beginner's Mind* — composed in California in the late 1960s but rooted in the Caodong / Sōtō house of Dōgen's line — is the practice-side companion in English, with the explicit just sitting instruction the southern Caodong house had carried since the twelfth century. On the side of the recognition the school's instructions point at, Adyashanti's *Do Nothing* — Adyashanti's own training is in the Sōtō Zen lineage of Maezumi Roshi, two transmissions removed from the Caodong house — is the index's clearest contemporary instance of the no-effort attention the southern Caodong line cultivated. The Plum Village and Thich Nhat Hanh on emptiness material carries the Vietnamese Thiền inheritance, the third major export of Chinese Chan, with its own particular synthesis of the Linji-line kōan sensibility and the engaged-Buddhist social commitment. The Zen entry maps the Japanese descent in more detail; the figures the Japanese tradition treats as ancestors — Bodhidharma, Huineng, Dōgen — each have entries on the Chinese-side material the lineage carries.
What it isn't
Chan is not unique to China in its emphasis on direct meditative recognition over scholastic doctrine — the Indian dhyāna tradition the school's name preserves was carrying the same emphasis before its Chinese reception — and is not antinomian in the way some of the popular Western literature has presented it. The transmission outside the scriptures motto is a polemical compression, not an institutional reality: Chan monasteries trained their monks in the Diamond, the Lankāvatāra, the Vimalakīrti and the Platform Sūtra and produced one of the largest bodies of commentary literature in the Chinese canon. Chan is also not synonymous with Zen: the Japanese branch the West has tended to encounter first is one of three major exports of the parent tradition, and its particular Sōtō / Rinzai polarity is a Japanese refinement of distinctions the Chinese houses had drawn differently. And the school is not, despite the popular reception, anti-intellectual; the same houses that produced the kōan collections produced the most sustained Chinese-language treatments of Madhyamaka emptiness analysis and the Yogācāra consciousness-only literature. The motto's not founded on words and letters names the goal of the practice — a recognition that words and letters were always pointing at — not a rejection of the textual apparatus through which the tradition transmitted its own working knowledge of how to point.
