Trần Anh Ninh trích yếu khẩu quyết từ Hoàng Nguyên Cát, làm rõ huyền quan nhất khiếu và công pháp thiên nguyên. Bản sơ tập đăng trên Dương Thiện bán nguyệt san; vì sợ lậu thiên cơ nên chưa hoàn thành toàn bộ.
Ứng dụng: Thực tu khẩu quyết phái ẩn tiên / Hoàng Nguyên Cát qua lăng kính Tiên học.
陈攖宁早年仙学专著（初集），据清光绪间江西丰城先生所传二书「提要钩玄」，专聚「玄关一窍」散见条文，删繁醒目，成系统口诀。核心：全书精华在玄关一窍；言理者多不言诀、言诀者多不言理，故以分类比条补其缺。兼涉男女丹工异同，并曾详解孙不二十四首次第。立场是仙学实修：重诀不重文、贵逆不贵顺，反对把秘法轻传外国或泛滥无戒。
⚡ Ứng dụng: 把零散玄关论述整理成可循读的钩玄体系，作内丹筑基开窍的口诀索引。
🔗 Liên quan: 孙不二元君女功内丹次第诗注；参同契讲义；金丹三十论
The text proves that oral formulas (koujue) are compressed causal operators: each phrase is a trigger that reconfigures attention and qi only if the practitioner already holds the right premises. “Hooking the profound” means extracting the invariant logic from variant wordings so one is not enslaved to a single master’s phrasing. Thus lineage secrets are portable algorithms, not magic strings.
1) Convert every BaZi slogan (“kill the official to seek wealth”) into a conditional: IF day master strong AND official excessive THEN… 2) Keep a personal hook-xuan notebook: formula → premises → somatic test → result. 3) Never apply a fire-timing koujue in a chart year that lacks fire support. 4) Cross-check three lineages’ phrases for the same stage (e.g. zhuji) and keep only the shared causal core. 5) Teach students the premises first; give the phrase last so it cannot be fetishized.
Unlike narrative 《钟吕传道集》, this work is meta-methodological: it argues about how secrets work. It differs from printed public scriptures by treating orality as compression technology, and from purely academic philology by requiring embodied verification of each hook.
