Bodri, arguing for the Zen route over the forcing techniques, p 572:
when you avoid using a forceful artificial technique, you don't have to be cognizant of so many warnings about gong-fu going astray either, which is a big benefit just by itself.
[RESONANCE] It is the phrase a big benefit just by itself that does it. He is counting the absence of a hazard as a positive feature of a method — and nobody counts that.
Curricula are compared on what they deliver. Nobody compares them on what they cannot break.
And once it is said, the tantric manuals look different. Every warning in them about incorrectly diffused drops, overheated channels and deranged chi is a hazard created by the intervention. Those failure modes do not exist for someone who never ran the technique. The manual's safety section is a list of injuries the manual is responsible for.
The vault already holds the two halves separately and has never joined them.
You Cultivate the Body So You Can Forget It establishes that body work is scaffolding — necessary, and never the building. The Four Descending and Ascending Blisses carries Tsong Khapa's complaint that the manuals omit dosage, timing and injury avoidance.
Put them together: scaffolding that must come down anyway, and that can fall on you while it is up, and whose erection manual is missing the safety pages.
The generalisation is a comparison rule, and it is missing from most fields: when two methods reach the same endpoint, the faster one's failure surface is part of its cost, and the slower one's absence of failure modes is part of its yield. Medicine has this — number needed to harm sits beside number needed to treat. Almost nothing else does. Not pedagogy, not training, not software practice, not spiritual instruction.
Same shape, different context: an intervention that generates the risks it then manages. Iatrogenic harm is the medical name; the manual's safety chapter is a list of its own injuries is the general one.
Against the vault's own instructional material — the Hughes drills, the tantric protocols, every forcing technique it carries — is the failure surface ever priced? The suspicion is that it never is, in any of them, and that the vault has been recording methods at their advertised yield.
Promotion criterion: find three carried techniques whose sources warn about their own failure modes, and check whether any source treats the absence of those failure modes in an alternative as a benefit rather than as a lack of power. If Bodri is the only one, that sentence is unusual enough to be worth a page of its own.
Next action: run the three-technique check; if it holds, propose the-failure-surface-a-method-creates as a cross-domain candidate and write the mechanism sentence before assuming it passes.
