The Mystic Pivot of Earthly Order: A Study on the Ancient Origins of the Six Combinations and Qi Transformations of the Twelve Earthly Branches
This article offers an in-depth investigation into the pre-Qin, high-antiquity origins and inner rationale of the Six Combinations and their Qi transformations among the Twelve Earthly Branches (e.g., Zi-Chou combining to transform into Earth). Through textual examination of the Earthly Branches' origins, their connection with Jupiter's orbital cycle, the correspondences between the twelve months and the twelve sovereign hexagrams, and the spatial positioning of the four Earth-branches at the four inter-cardinal directions, the essay reveals the profound astronomical and yin-yang philosophical underpinnings of the Earthly Branch system as a cornerstone of Chinese metaphysical arts.
General Preface
Heaven has its warp; Earth has its weft. The warp is the constant Way of Heaven -- the courses of the sun, moon, and stars. The weft is the constant pattern of Earth -- the breath of mountains, rivers, and peaks. Since the sages of high antiquity first gazed upward at celestial phenomena, peered downward into terrestrial forms, and penetrated inward to the affairs of humankind, the study of the Heavenly Stems and Earthly Branches has served as the very foundation of Chinese metaphysical arts, the root of calendrical reckoning, and the pivot of yin and yang.
The Twelve Earthly Branches -- Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai -- bear simple names yet carry the most profound significance. The ancients used them to reckon months, hours, and years, yet their utility extends far beyond mere timekeeping. Among the Branches, there are clashes and combinations, punishments and harms, triple combinations and six combinations -- an intricate tapestry of transformations, magnificent in scope. Among these, the doctrine of the "Six Combinations and Qi Transformation" is especially arcane:
Zi and Chou combine to transform into Earth; Yin and Hai combine to transform into Wood; Mao and Xu combine to transform into Fire; Chen and You combine to transform into Metal; Si and Shen combine to transform into Water; Wu and Wei combine to transform into the qi of Sun and Moon (or what may be called Greater Yang and Greater Yin).
Whence do these six pairings of combination and transformation originate$1 What is their rationale$2 What intrinsic connection do they bear to the workings of Heaven and Earth$3 Do the pre-Qin classics already contain intimations of them$4 What was the deeper intent of the ancient sages in establishing these principles$5
This essay attempts, departing from pre-Qin and Han dynasty texts, to search broadly and cite widely, offering a thorough investigation of the ancient origins, astronomical background, yin-yang philosophy, Five-Phase mechanisms, and applications of the Six Combinations and Qi Transformations in ancient calendrical and divinatory arts. The aim is to restore the original face of this doctrine and reveal its deeper meaning. The work comprises twelve chapters and approximately fifty thousand words, offered in the hope of providing a detailed reference for students of the fundamental roots of Chinese metaphysical arts.
