This scripture proves that premature death and spiritual failure are partly caused by endogenous parasites—the Three Corpses and Nine Worms—that report sins and erode vitality, so longevity is a hygienic-moral war against internal destroyers. It argues that fasting dates, drugs, spells, and ethical restraint work because they starve and expel these agents. Preservation of life is therefore simultaneous physiological purge and moral disarmament of the corpses’ accusations.
1) In BaZi, heavy resource+wealth indulgence patterns may flag corpse-feeding lifestyles—prescribe abstinence cycles. 2) Observe traditional 庚申 watches or modern equivalents: all-night clarity to prevent corpse ascent. 3) Combine dietary simplification with confession/rectification of habits the worms ‘report.’ 4) Use metal and fire days for cutting/purging protocols when medically appropriate and lineage-authorized. 5) Track vitality after purge periods as empirical feedback, not superstition alone.
Unlike 功过格, which scores deeds externally, this text internalizes the enemy as organisms of sin and decay. It differs from pure neidan’s sublimation language by retaining a parasitology of evil. Its logic is medical-demonological hybrid: ethics as anti-parasitic regimen.
