Undersea Eye – The Core Principles of I Ching (Six Lines) Divination (Haidi Yan海底眼)

A Must-Read Classical Text on Six Lines Divination, Wen Wang Gua, and the Na Jia Method (English Edition) Written by Wang Zi Recompiled by He Shen (courtesy name Xinheng) Revised by Xu Dasheng (Before circa 1244 CE) Translated by Xuan Wanyan Undersea Eye (Haidi Yan) is an essential classic to deepen your understanding. This concise yet profound text has guided practitioners for centuries alongside Fire Pearl Forest and I Ching Divination – Complete and Restored. It records the core teachings transmitted by the reclusive master Wang Zi, systematized by He Shen, and verified by Xu Dasheng—a key figure in Chinese metaphysics. The book emphasizes foundational concepts of the Na Jia method, including Five Element correspondences and applications, and features mnemonic verses to aid learning. Its in-depth treatment of the Six Relationships makes it one of the most authoritative and valuable texts in the entire Six Lines Divination tradition. As one of the most important classical works within the Na Jia tradition, Undersea Eye holds significant scholarly value for anyone seeking a deeper, research-oriented understanding of the method. This English edition—possibly the first—was translated by Xuan Wanyan, a Columbia University graduate from a family steeped in the I Ching tradition, making this once-esoteric system accessible to non-Chinese readers while faithfully preserving its original depth.
