The Human Body

experience noteanonymousThe teacher's lay-physiology of sitting: breath and distraction, brain and glucose, blood pressure, circulation, the two nervous systems, and the dantian — the six-part account of the body that underlies the whole practice series

The chapter

The teacher’s physiology, in its own order: (1) the breath is the index — count it: the faster you breathe the faster you spend, the more you spend the more you think, the more you think the more you suffer; (2) the brain runs on oxygen and glucose, and sitting entry is the state of being awake and clear — the chapter’s single sentence that the site’s sleepiness page takes as the archive’s answer to drowsiness; (3) blood pressure is born at birth, and its formation story ends in a rule — pregnant women must stay relaxed; (4) the heart’s six vessels and the lungs’ lower half — reverse abdominal breathing inflates the lung sideways until lung pressure exceeds the atmosphere, and that is its fatal side effect; (5) the body repairs in sequence — skin, muscle, organs, sinews, bones — and the nervous system the teacher describes is two systems, not one; (6) the dantian is the small intestine’s neighborhood, and its real content is the two great vessels on the spine — 丹田不通就没有禅定, without the dantian open there is no dhyana.

Three layers, kept apart

• The practitioner layer. This chapter is a lecture, not a Q&A — the practitioner layer is thin by design (the teacher’s standing instruction: 发问——先看完前面的帖子再问, read the previous posts before asking; and the blunt ceiling: 你这辈子能修到四禅就算到顶了, the four-dhyana mark is the practical ceiling for this life; the formless attainments beyond need a liberated guide). What the practitioner layer holds instead is the teacher’s own address: the chapter is written 留给各位，就算我不在了，大家也不至于盲目的乱撞 (left for you, so that even if I am gone you will not blunder blindly) — the series’ will-and-testament register, and the site files it as such: this is the archive teaching as legacy, not as live exchange.
• The teacher layer, with its own boundary declaration. The chapter’s centerpiece is the teacher’s explicit divergence from medicine, registered verbatim in paraphrase: 这里开始和目前的医学理论可能有不同的地方！我们是修行人，对身体的观察和了解要比医学还要进步 (from here on there may be differences from current medical theory — as practitioners our observation and understanding of the body outruns medicine), with the corollary that the ancient enlightened ones were all physicians, describing the body in the vocabulary of their age. The site treats this declaration as the archive’s most important sentence about itself: it is the teacher telling his readers exactly where his account leaves the checkable world — and the site’s verification discipline applies to everything after it. The chapter’s specific claims are registered under the standing flags:
  • Physiology claims, registered not endorsed. The two-nervous-system doctrine (the spinal trunk for commanded movement; the second system behind the ears through the rib muscles to the organs; most of both dormant in ordinary people), the blood-pressure origin story (birth’s atmosphere plus the startled belly squeezing the abdominal blood into the heart), the newborn-blood-pressure paper (30–60 mmHg normal, above 60 a life of fighting illness, because the unborn hear the mother’s fright), the nerve-signal speed (20 m/s) and the nerves-around-the-earth-twice figure, the hormone doctrine (胺多酚 — the teacher’s transliteration of endorphin — as the happiness hormone), and the breath-rate statistics (Americans breathe fastest and have the most mental illness; Korea second and first in suicide) — all registered as the teacher’s lay-physiology and unverified claims, per the site’s health-claims rule, with the site’s standing non-medical-advice declaration.
  • Extraordinary claims, cross-linked. The antediluvian-civilization claim (38% atmospheric oxygen before the great flood, against today’s 20.98%, with the assertion that archaeology confirms the taller, longer-lived bodies) and the Buddha-era breath-rate claim (eight breaths a minute in the Buddha’s time) cross-link to the archive’s extraordinary-claims handling per the standing rule — registered as the episode’s content, not taken on.
  • Threshold claims, registered as the tradition’s. The near-awakening markers (fewer than five breaths a minute at rest, fewer than one a minute in sitting) and the dantian-claims (without the dantian no dhyana; the test — if someone cannot say what the dantian does, they are a 书呆子, a book-idiot) are the teacher’s own criteria, registered as such and not adopted by this site’s progress page, which keeps its own measure (months of the same practice).
• The alternative layer. The chapter contains one correction of received scripture, filed with the site’s source-criticism line: the first foundation of mindfulness is observing the body in detail — 观身不净 (contemplating the body as impure) is a device for generating renunciation, and aspiration is not practice (发心和实际修行不是一回事). The site notes the pattern: this is the same genre as the ch. 4 Anapanasati criticism (filed in EXP-028) — the archive reads its own sutras critically, and the site preserves both moments because they are the archive’s version of the site’s own discipline.
• The convergence point, stated plainly. Beneath the Buddhist frame and the divergent physiology, the chapter’s procedural core coincides with ordinary prudence on three points the site can state without endorsing any doctrine: gradual repair (the five-stage sequence, two to three years for the bones — the same gradual-change rule as EXP-028’s three months for the breath); dose-limits (the breath’s 20% rule carried over; the standing warning against reverse-breathing lung pressure); and the target defined as the body’s changes, not the states (咱不谈禅定中的境界，但完全可以靠身体的变化来描述修行进度 — the same description-by-body-changes discipline as the ch. 4 Inception confession, now stated as the chapter’s own method). The site’s heat-and-sweat file holds the sensation side of the same body-changes language.

Why it is filed here

Because this is the archive’s theory chapter — the six-part account of the body that underwrites every practice instruction in the series (the breath curriculum of EXP-028, the prostrations of EXP-021, the dhyana map of EXP-016) — and the site files it beside the modern research that holds the boundary it crosses: the archive describes the body from inside practice, the research describes it from outside, and both are on the site, neither flattened into the other. The chapter also completes the site’s dantian and qi pages on their practitioner side: the tradition’s classical dantian, the archive’s two-vessels dantian, and the modern qi-research boundary now all stand in view of each other — which is exactly what this site exists to let a reader do.
