Xiao Zhiguan: The Five Adjustments (6th c.)
Zhiyi's beginner's manual codifies the five pre-sitting adjustments — diet, sleep, body, breath, mind — the vocabulary that crossed traditions.
The event
In the second half of the 6th century, the Tiantai master Zhiyi (538–597) composed the Xiao zhiguan (“Smaller Calming-and-Insight”) — a beginner’s meditation manual written for a lay practitioner. Its fourth chapter codified the five adjustments (调五事): diet, sleep, body, breath, and mind.
The chapter’s method set the template for Chinese sitting instruction ever after: settle the posture in nine graded steps; expel stale breath slowly (three times) before breathing in; pursue the breath that is “fine and continuous, as if present, as if absent” (气息绵绵密密，若有若无); correct the four faulty breaths (audible, labored, unfree, uneven); and re-check body, breath, and mind before, during, and after sitting.
Why it matters
- A Buddhist manual’s vocabulary becomes the common language of Chinese sitting. The tiao-shen/xi/xin trio was adopted across Daoist and Neo-Confucian instruction — the clearest documented case of cross-tradition technical borrowing in this field.
- Regulation, not control. The manual’s repeated verb is 调 (harmonize), and its failure-model is forcing. This is the classical warrant behind this site’s sitting protocol and its stance against breath-forcing.
- Sleep appears as a practice variable. The five adjustments formally recognize that the body’s rest-debt shows up on the cushion — the pre-modern ancestor of the modern fatigue reading of meditation drowsiness (see drowsiness).
