Supplement of Nine Discourses 易数钩隐图遗论九事

Authored by Liu Mu of the Northern Song Dynasty.

The Secret Catalogue of the Southern Song Dynasty recorded a work titled "One Volume of Zhouyi: Remaining Sayings of Predecessor Confucians by Liu Mu", which is certainly this book.

The existing version in The Daozang consists of one volume, classified under the Spiritual Diagrams category of the Dongzhen Section.

Supplement of Nine Discourses

The version in the Siku Quanshu (Complete Library of the Four Treasuries) is appended to the end of Diagrams for Unveiling the Hidden Meaning of the Zhouyi Numbers.

This book contains nine illustrated discourses, presented in the following order: Taihao Receiving the Dragon Horse Bearing the Diagram, A Formula for Deducing Abundance by Expanding the Sixty-Four Hexagrams, The Fifty Great Expansion Numbers, The Eight Trigrams Evolving into the Sixty-Four Hexagrams, Distinguishing Yin and Yang Hexagrams, Returning to Perceive the Mind of Heaven and Earth, The Hexagrams Concluding with Wei Ji (Unfinished Success), The Method of Divining with Milfoil Stalks, and Diagram of Yin-Yang Pitch Pipes. In this book, the author further elaborates on his diagram-based Taoism-influenced Zhouyi studies theory, maintaining that his ideas address aspects not covered by predecessor Confucian scholars—hence the title reference to "Remaining Sayings of Predecessor Confucians", with its theoretical framework closely connected to the five elements theory.
