道门还元类经诀，宗旨「仙道还元」：由后天返还先天元精元气元神。理路与金丹「归根复命」「还丹」一致：元精化为交感精、元气化为呼吸气、元神化为思虑神，须逆炼使三元归真。下手重凝神气穴、固济三宝、虚极静笃以候先天；成则形神还元、与道合真。文风口诀化，强调还元非服食外药，而在身中逆修。
⚡ Ứng dụng: 作为「炼精化气—炼气化神—炼神还虚」的总名目，检查三元是否仍泄漏于后天。
🔗 Liên quan: 《清静经》《五篇灵文》《入药镜》
The scripture proves that the immortal path is identical with “returning to the origin” (还元): all techniques are true only insofar as they reverse dispersion back to the pre-heaven source. Immortality is not endless forward survival of the post-heaven person but completion of reversion; thus “true” marks correspondence with origin, not miraculous deviation from law. The end-state is the beginning recovered consciously.
1. Evaluate every BaZi remedy by the return test: does it reduce dispersion and restore origin-like simplicity? 2. Prefer reverse interventions (rest, silence, containment) when charts show hyper-output. 3. Track annual luck as approach/departure from personal origin pattern (day-master balance), not only as wealth events. 4. End sessions with one 还元 act (breath to root, gratitude without grasping). 5. Discard techniques that produce more complexity, dependency, or identity inflation.
Compared with 无根树’s graft metaphor, 仙道还元真经 states the same reversion in scriptural definitional form—origin as the truth-condition of all methods. It is more slogan-complete and criterion-focused than 悟道录’s long experiential dialectic. Its unique logical role is final-criterion: whatever does not return to origin is not the immortal path, regardless of brand.
