Zhiyi (智顗)
Zhiyi 智顗 (538–597), the Tiantai founder whose beginner's manual supplied the operating language of Chinese sitting — the five adjustments and the four faulty breaths.
Direct answer: Zhiyi (智顗, 538–597) was the founding systematizer of the Tiantai (天台) school of Chinese Buddhism and the author of the most influential meditation manual in Chinese history — the short Xiao zhiguan (text page). This site documents him not as a Daoist figure but as the historical source of the operating vocabulary that Daoist and Confucian sitting instruction later absorbed: the five adjustments and the four faulty breaths. His historicity is as solid as any figure’s in the field.
Life (from Buddhist biographical sources)
- Born 538 in the Liang dynasty; became a monk young and studied under Huisi (慧思), the second patriarch of what became the Tiantai lineage.
- 567: went to Mount Tiantai (天台山) in Zhejiang, where the school took shape and its name.
- Served as spiritual teacher to Sui dynasty royalty; the school’s political reach made its texts and vocabulary normative across China.
- 594: at Yuquan Temple (玉泉寺) in Jingzhou, dictated the Mohe Zhiguan (“Great Calming-and-Insight”) — the mature statement of his meditation system — recorded by his disciple Guanding (灌顶, 561–632). The lecture series was left unfinished at Zhiyi’s death in 597.
- Among his many works, the Xiao zhiguan — a popular condensation of the same system, written for lay practitioners — became the traveling text: short, plain, and copyable.
Why he is on this site
Zhiyi matters here for one specific reason: his beginner’s manual became the common operating language of Chinese sitting. Three concrete transfers:
- The five adjustments (调五事) — diet, sleep, body, breath, mind — passed from Tiantai instruction into Daoist health manuals and Neo-Confucian quiet-sitting teaching. The modern Chinese word for breath regulation in sitting, 调息, is his (see tiaoxi).
- The four faulty breaths — wind, panting, gasping, resting — the standard diagnostic grid for breathing faults, reused verbatim in later non-Buddhist manuals.
- The sinking/floating pair (昏/浮) — dullness versus scattering — which the Zhu Xi school’s quiet sitting inherited, and which this site’s drowsiness and restlessness pages treat as the received distinction 昏沉 vs 散乱.
The boundary: Zhiyi’s system is Buddhist samatha-vipasyana with Buddhist metaphysics; what the Daoist tradition borrowed is the technique vocabulary. This site documents the borrowing, states the provenance on every page, and adopts none of the Buddhist doctrinal claims. Zhiyi is recorded here as a historical person whose manual crossed traditions — not as a Daoist.
Uncertainty preserved: biographical details rest on Buddhist hagiography and doxography; the dates and institutional facts are well established, the anecdotal texture less so.
