Sanming TonghuiVol. 1, On the Nature and Fortune of the Sixty Jiazi (verdicts & remarks)
Wu Wu Fire is the solar disc: in summer people dread it, in winter people love it. It dreads Wu Zi, Ji Chou, Jia Yin, and Yi Mao. Hidden God [Fu Shen], Yang Blade [Yang Ren], Nine Ugliness [Jiu Chou], Staff and Rod [Bang Zhang], Suspended Needle [Xuan Zhen].
When Wu Wu and Geng Shen meet each other, they are transcendent and extraordinary. Geng Shen is Pomegranate Wood, which flourishes in summer, so it delights in Wu Wu.
For the Fire Officer is prosperous, and the nature of Pomegranate Wood finds its proper season; Wu Wu is Fire at the peak of prosperity, delighting in Shen, where the Heavenly Horse provides mutual aid.
As for the Spirit-Head Lu [Shen Tou Lu], it is the dedicated position Lu of the Ten Stems, being the dedicated position of yin and yang and the spiritual convergence of Heaven and Earth.
It sets forth the true origin of the Ba Gua and elaborates the success and failure of the Five Elements, with firm and yielding pushing against each other, and existence and non-existence combining and transforming.
Therefore, Ren Zi Water corresponds to Kan of the north, and Bing Wu Fire represents Li of the southern palace.
Thus Bing Wu meeting Ren Zi is not considered broken, and Ding Si meeting Gui Hai is not considered a Clash; this is the wellspring of Water and Fire aiding each other, having the principle of husband and wife pairing together, with Kan and Li serving as the spirit and essence of man and woman.
But if Ren Zi meets Bing Wu, or Gui Hai meets Ding Si, Fire and Water are reversed in sequence, bearing the image of Before Completion [Wei Ji], which is not as favorable as Ding Si meeting Ren Zi or Bing Wu meeting Gui Hai.
