The title “Undersea Eye” (Haidi Yan, 《海底眼》) points to its central idea: in older usage it can mean a concealed mark, something not visible on the surface but decisive once found, and in divination it refers to the single deep indicator that clarifies the whole judgment. It restores clarity to practice by returning to first principles: the Six Relationships, Five-Element correspondences and applications, and memorable teaching verses that make rules easy to retain and apply. Studied alongside Fire Pearl Forest and I Ching Divination – Complete and Restored, it remains one of the most authoritative guides for building sound judgment and repeatable technique.Who it helpsIntermediate and advanced practitioners: a distilled framework that strengthens pattern recognition, timing, and decision rules.Teachers and researchers: historically anchored doctrine that clarifies terminology and resolves common disputes in Na Jia practice.Bazi practitioners: a complementary classic that connects Six Lines technique with broader Chinese metaphysics.Tarot readers and researchers of other divination systems: broaden your knowledge base with a rule-based method that adds specific timing and decision rules to symbol-driven readings.English editionThis Undersea Eye English edition (possibly the first in English) was translated by Xuan Wanyan, a Columbia University graduate from a family steeped in the I Ching tradition.
