The Pivot of Terrestrial Order: A Study of the Six Conjunctions and Qi Transformations of the Twelve Earthly Branches in High Antiquity
This essay strips away the veneer of divinatory numerology to return to pre-Qin astronomy and cosmology, offering a rigorous investigation of the true nature of the Six Conjunctions of the Twelve Earthly Branches — Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, and the rest. It focuses on the astronomical 'conjugation' essence of the Six Conjunctions, and the philosophical implications — sealing and storing, sprouting and rising, refining and transforming, revolution and change — concealed behind their 'qi transformations.'
Chapter Seven: General Discourse — The Cosmic Vision of the Ancients as Seen through Qi-Transformation
Surveying the qi-transformations of the Six Conjunctions of the Twelve Earthly Branches, we readily discern a rigorous system of "natural philosophy of high antiquity":
- Zi-Chou transforming into Earth: simulates the sealing and storing of the bitter cold at the Winter Solstice, when all things return to their roots.
- Yin-Hai transforming into Wood: simulates Water engendering Wood — life cracking its shell and emerging.
- Mao-Xu transforming into Fire: simulates the interplay of spring's generation and autumn's killing, the surging clash of Yin and Yang producing energy (thunder-fire).
- Chen-You transforming into Metal: simulates the mutual engendering of Earth and Metal — the austere harvesting and revolution of autumn.
- Si-Shen transforming into Water: simulates the convection of hot and cold, the clash of Metal and Fire transmuting into liquid.
- Wu-Wei transforming into Fire/Earth: simulates the supreme Yang of the Summer Solstice — light and heat shining together in full glory.
A Final Philosophical Reflection
Why did the pre-Qin classics place such importance on "conjunction and transformation"$17
Because "solitary Yin does not engender; isolated Yang does not grow" (gu yin bu sheng, du yang bu zhang).
If the Earthly Branches do not conjoin, they remain isolated points in time; once conjoined, they produce "transformation" (hua) — they produce change and flow.
This is precisely the core thought of the Zhouyi (Book of Changes): "Ceaseless generation upon generation — this is what is meant by Change" (shengsheng zhi wei yi).
The transformations wrought by the Six Conjunctions are, in reality, the attempt of the ancients of high antiquity to use a symbolic system to capture the patterns of energy transformation in the cosmos. Wood transforms into Fire, Fire into Earth, Earth into Metal, Metal into Water, Water into Wood — cycling round and round, without beginning and without end.
To study the conjunctions and transformations of the Earthly Branches is not merely to study the arts of divination. It is to use them as a lens through which to glimpse that great age when "humans and spirits walked side by side, and Heaven and Earth moved in unison." Behind the seemingly superstitious formulas lie the most artless yet profound truths the ancients discovered about astronomy, geography, physics, and meteorology.
