Structural Analysis, Meaning, and Philosophical Inquiry of the Hexagram Huotian Dayou (Fire Over Heaven)
This article systematically investigates the fourteenth hexagram of the *I Ching*, *Huotian Dayou*, analyzing its structure (Li over Qian), delineating the rich connotations of 'Great Possession,' and interpreting its principle of 'One Softness in Supremacy Responded to by Five Yangs' through the lens of Pre-Qin texts, thereby revealing its profound significance in ancient political philosophy.
General Preface
The Zhou Yi (Book of Changes) is the treasured classic of the Three Dynasties and the essential teaching of the ancient Sages. From Fuxi drawing the trigrams, King Wen affixing the judgments, the Duke of Zhou changing the lines, to Confucius supplementing the commentary, its profound principles have been passed down through successive sages, and its depths cannot be fully fathomed by a single generation or a single person. Among the sixty-four hexagrams, each one is a microcosm of heaven and earth and a mirror reflecting human affairs. The hexagram "Da You" (䷍), occupying the fourteenth position, features Li (☲, Fire) above Qian (☰, Heaven)—Fire in the Sky—symbolizing light universally illuminating and all things flourishing. It truly represents an image of great abundance and maximal possession.
Why is it named "Da You" (Great Possession)$1 How can the union of Fire and Heaven culminate in the virtue of Great Possession$2 Why does a single yielding line occupy the position of honor, responded to by five firm lines$3 Why does the Judgment state, "Its virtue is firm and persistent, yet civilized and bright" (其德刚健而文明)$4 Why does the Image commentary state, "It stops evil and promotes good, thereby conforming to the mandate of Heaven and enjoying its blessing" (遏恶扬善，顺天休命)$5 These questions are precisely what scholars of the Yi must deeply investigate.
This article aims to conduct a comprehensive, in-depth, and systematic study of the hexagram "Fire over Heaven" (Da You) from the perspectives of the Pre-Qin and high antiquity. The primary sources cited are the Zhou Yi classics and commentaries, supplemented by Pre-Qin texts such as the Book of Documents (Shangshu), the Book of Odes (Shijing), the Zuo Zhuan, the Discourses of the States (Guoyu), the Book of Rites (Liji), the Rites of Zhou (Zhouli), the Analects of Confucius (Lunyu), the Mencius (Mengzi), the Laozi, the Zhuangzi, the Xunzi, the Han Feizi, the Guanzi, and the Lüshi Chunqiu. We also draw upon the interpretations of Han Dynasty classicists, striving for rigorous textual research, coherent interpretation of principles, and presentation that is both profound and accessible for the reader.
The entire text is divided into twelve major chapters, beginning with the structure of the hexagram image, gradually delving into the inherent principles, the line statements (Yaoci), the judgments of the Image and Judgment commentaries (Tuan and Xiang), historical case studies, philosophical contemplation, and applications for governance, ultimately concluding with the profound significance of the Dao of Da You for ancient political philosophy, ethical thought, and cosmological concepts.
