清·陈淡埜（虚虚子）编撰，强调“相必揆理、衡必求真”。分杂论、谈性、问答、元机赋、十二宫、五官、掌法、气色、疾病捷径等。以理统术：器宇、三光、六府、性情人品并重；含掌纹骨法、合相破相格诀。纠正江湖妄断，主张理真形显、性与相合，为清代相学中较具哲理化之总结本。
⚡ Ứng dụng: 相人时以义理与真形互证，结合器宇性情与掌面气色，避免纯形格迷信。

It proves that physiognomy must be re-weighed against true principle (理) so that vulgar mark-superstition is cut away and only coherent causal form remains. The text’s logic is reformist: without philosophical calibration, the art drifts into marketplace fraud.
1. For every folk rule, demand a phase/qi mechanism or discard it. 2. Re-rank features by principle: spirit and harmony beat isolated wealth signs. 3. Align physiognomy language with BaZi elemental logic to one shared ontology. 4. Refuse fear-based readings that cannot propose cultivation countermeasures. 5. Write 'why' under each judgment to keep the scale of 衡 true.
Unlike 神相全编’s collect-everything impulse, 相理衡真 prunes and philosophizes. Unlike 冰鉴’s statecraft focus, it aims at doctrinal correctness of the art itself—truth-weighting rather than talent-sorting alone.
