详论三关之说-卷首

详论三关之说

如子上初关危十三度，中关虚六度，末关女二度，以 首尾出入度分，初中末度为三关。九五度为卒，三合吊者，
不过三度，四正冲者，不过一度。煞居三方之正垣，其人

死于上节，煞居初关。死于下节之前，上节之后，煞居末 关。死于下节之后，上节之前， 一度节后一 日死，二度节 后二日死，三度节后三日死，并依度数加减日分上取之， 无有不准。

A Detailed Discussion on the Theory of Three Passes - Volume Preface

Overall Paraphrased Translation
The ancients divided each celestial palace (such as the Zi Palace) into "Three Passes"—the Initial Pass, Middle Pass, and Final Pass—by observing the degrees of constellations along the ecliptic 🌌. Each pass corresponds to a specific range of constellation degrees. For example: the Initial Pass of the Zi Palace corresponds to 13 degrees of the Wei Constellation, the Middle Pass to 6 degrees of the Xu Constellation, and the Final Pass to 2 degrees of the Nü Constellation. By observing the pass and specific degrees where a malevolent star 🌟 is located, the exact timing of a person's death can be precisely calculated. The logic is as rigorous as a mathematical formula, even allowing for pinpoint accuracy to specific days around solar terms.

🧠 In-Depth Understanding

Core Concepts 💡

• Division of Three Passes: Quantifying the trajectory of constellations into three intervals—Initial, Middle, and Final—combined with solar terms (e.g., Winter Solstice, Summer Solstice) to form a spatiotemporal coordinate system.
• Location of Malevolent Stars: Calculating the relationship between the time of death and solar terms based on the pass (Initial or Final) and specific degrees (1 degree ≈ 1 day) where a malevolent star is located.
• Precision Control: A margin of error of 3 degrees is allowed for Three Harmony combinations, while only 1 degree is permitted for Four Cardinal Clashes, reflecting the ancients' quantitative thinking of "correspondence between heaven and humanity."

Modern Interpretation 🌟

• Essentially, it is ancient astronomical statistics 🌠: Summarizing the correlation between celestial phenomena and life cycles through long-term observation, similar to "time series analysis" in modern data modeling.
• Correspondence between solar terms and passes: The ancients used solar terms as nodes on the timeline (e.g., "upper solar term" refers to the start, "lower solar term" refers to the end), anchoring the time of death within natural cycles.
• Logic of "converting degrees to days": 1 constellation degree ≈ 1 day, essentially transforming spatial coordinates (constellation positions) into temporal coordinates (days until death), reflecting a unified view of time and space.

Practical Value ⚡

• Significance for Historical Research: Reveals the deep integration of ancient Chinese astronomy and numerology, providing empirical material for the history of science and technology.
• Lessons in Thinking Patterns: Emphasizes systematicity (constellations + solar terms + degrees) and precision (error control), applicable to modern project management or risk warning models.
• Transformation of Cultural Symbols: The concept of "Three Passes" can be abstracted as a metaphor for dividing key life stages (e.g., youth, middle age, old age), offering insights for life planning.

Philosophical Reflections 🤔

• Dialectics of Fate and Freedom: The ancients attempted to "quantify" life and death through constellation degrees, which may seem fatalistic but actually隐含 a reverence for natural laws and a spirit of exploration.
• Harmony Between Micro and Macro: Individual life rhythms (time of death) and cosmic movements (constellation trajectories) are framed within the same system, reflecting the cosmology of "harmony between heaven and humanity."
