道藏洞真部靈圖類，宋蕭道存撰（序稱得華陽施肩吾所授），常與《指玄圖》同卷。以「太極混元」總攝金丹：金丹為大道之源，大無外、小無內，與天地人同構。圖列三景、三才定位、五行生剋、水火既濟等，示先天混元一炁如何分陰分陽、如何在人身復歸太極。義理上接鍾呂、施肩吾一系「形神俱妙」，反對只空心遺形；強調立天立地與人同焉，修真即在人身內重演宇宙開闢。
⚡ Ứng dụng: 學內丹先立「人身一小太極」圖式：看八字亦先看日主能否為太極之樞，再布三才五行是否能混元一炁、水火既濟。

The diagram corpus proves that Taiji-Hunyuan cultivation can be made cartographic: stages of yin-yang ascent/descent, three powers, and embryo-breathing are real transitions that images can fix better than prose alone. If the path is mappable, it is teachable and error-checkable. Proof object: visual isomorphism between cosmos and body process.
1) Draw your current practice location on a simple Taiji-Hunyuan sketch monthly—locate yourself. 2) Match BaZi climate (cold/hot, dry/wet) to which diagram phase needs support. 3) Use moon-phase diagrams to schedule quieter gathering vs circulating days. 4) Teach beginners with one image before vocabulary overload. 5) When stuck, return to earlier map node rather than adding exotic methods.
Unlike purely textual Qingjing notes, this work proves by graphic systemization. It is more cosmogonic-overview than the more ‘pointing to mystery’ sequel, and less commercially sequential than Jinye Huandan ‘seal verification’ sets. Relative to ritual weiyi scriptures, its map is interior cosmography.
