Ứng dụng: 内丹·钟吕系统
题唐施肩吾（华阳真人）撰、李竦编，五卷。按「识→养→补→真→炼」阶次组织钟吕系内丹：卷一识道识法识人识时识物；卷二养生养形养炁养心养寿；卷三补内补炁补精补益补损；后卷论炼形、炼气、炼神与五仙（鬼仙、人仙、地仙、神仙、天仙）品位。强调「天下无二道」「以法入道，以道求仙」，综合胎息、还丹、龙虎铅汞与西山群仙口诀，是唐代至北宋钟吕丹法的系统纲要。
⚡ Ứng dụng: 按识—养—补—炼次序修钟吕内丹：先明道法时物，再养炁补精，终炼神还虚。

The text proves that many named immortals of the Western Hills converge on one alchemical truth: scattered techniques are surface variants of a single return-to-the-real (會真) process—essence, qi, and spirit refined in orderly stages—so orthodoxy is the shared internal logic, not the multiplicity of stories.
1) Build a personal curriculum with stages (stabilize essence → circulate qi → clarify spirit) and refuse random technique hopping that skips stages. 2) When BaZi shows strong Output but weak Resource, emphasize earlier essence conservation stages before advanced visionary methods. 3) Use 'many masters, one real' as filter: adopt a method only if it maps onto the three-treasure sequence. 4) Journal weekly which treasure was trained—prevents illusory progress in only one layer.
Unlike single-master image-biographies (金蓮像傳), this text synthesizes a regional immortal cohort into technical unity. Unlike pure laboratory waidan readings of Cantongqi, it is explicitly multi-immortal and instructional in neidan key.
