It proves that the Green Satchel tradition is a sequenced transmission: cosmology must be ordered into pedagogical and operational layers before it can be used without self-contradiction. The 'order' (序) is itself an argument—that wrong sequence (technique before principle, or compass before dragon) produces systematic error.
1. Study order: Yin-Yang/Five Phases → form grammar → liqi numbering → case application. 2. When a rule conflicts, walk backward up the sequence until the first broken premise. 3. Structure BaZi study the same way: stems-branches physics before god-schema tricks. 4. Refuse 'secret formulas' that skip justification layers. 5. Teach clients only the layer they can verify, to avoid cargo-cult rituals.
Unlike 青囊经 as root scripture of principles, 青囊序 is meta-logical: it argues for the arrangement of knowledge. Unlike 青囊奥语’s compressed riddles, it aims at transmissibility and order rather than esoteric density.
