The Eight Major Classical Saju Texts
Based on datasets of the eight major classical literature sources of divination studies, rather than interpretations biased toward a single school of thought.
Yeonhae-Japyeong (淵海子平)

An encyclopedia of Saju compiled by Man Min-yeong of the Ming Dynasty. It is the only orthodox text recognized by the state (government office) and encompasses vast theories.
Jeokcheonsu (滴天髓闡微)
An essential read that delves deepest into the 'logic' and 'principles' of Saju. It elucidates the flow of Qi and the principles of Suppression beyond mere fortune and misfortune.
Japyeong-Jinjeon (子平眞詮)
The textbook on Chart Patterns and Useful Gods. It presents the most sophisticated structural theory for judging social utility and success, essential for modern social analysis.
Gungtong-Bogam (窮通寶鑑)
The absolute standard for Seasonal Useful Gods. It is a treasure trove of Image Theory, explaining the influence of seasons and climate on human destiny through natural principles.
Myeongri-Yakeon (命理約言)
A practical book by Jin So-am of the Qing Dynasty that concisely organizes complex Saju theories. It reduces the principles of Generation and Restriction into clear formulas.
Sinbong-Tonggo (神峰通考)
A book that sharply criticizes contradictions in existing theories and presents independent views. It warns against blind faith and emphasizes an empirical attitude.
Myeongri-Tamwon (命理探源)
A masterpiece that reinterprets and integrates classics from a modern perspective. It fundamentally explores the principles of Symbolic Stars and Five Elements, laying the foundation for modern application.
