渊海子平
Yuan Hai Zi Ping · Song Dynasty (960-1279 CE)
The foundation work of Zi Ping (Four Pillars) school — establishes Day Master as the axis, Ten Gods as the framework, Five-Element transformation as the engine.
Background
Compiled by Xu Sheng in the Song dynasty, Yuan Hai Zi Ping collects the teachings of Master Xu Zi-ping (徐子平) and his predecessors. Master Xu broke from the Tang-era practice of reading the year-pillar as primary, and established the Day-Master as 'self' with the other seven characters as 'other'. This single shift is the structural foundation of all BaZi reading for the past thousand years. The text covers Five-Element generation and control, the Ten Gods, useful-element selection, and pattern judgment — every subsequent BaZi treatise draws from it.
Concepts this text grounds
- Day Master as the analytical axis
- The Ten Gods — relational archetypes around the Day Master
- Five-Element generation, control, and balancing
- Pattern identification (special vs. regular格局)
- Useful-element selection (用神)
Selected excerpts
All excerpts below are public-domain classical Chinese. English glosses are modern reviewer-polished renderings of the historical English translations.
「夫人禀天地之气,受阴阳之精。」
A person is endowed with the qi of heaven and earth, receives the essence of yin and yang.
卷一 · 论命
「以日为主,年为本,月为提纲,时为辅佐。」
Take the Day Stem as the self set at the centre; the Year is the root, the Month the guiding headline, the Hour the supporting context — the fundamental break from the old year-based method.
论日为主
How Minglitang uses this text
Minglitang's Mastery deck draws directly from Yuan Hai Zi Ping for three of the twelve cards: the Self card (自我之相), the Ten Gods card (十神格局), and the Useful-Element card (用神调候). Day-Master analysis is the first move every master makes when reviewing a reading.
Guidance, not prophecy. For reflection, not decision.
