Sanming TonghuiVol. 1, On the Nature and Fortune of the Sixty Jiazi (verdicts & remarks)
Xin Si Metal is deep, shadowed metal mixed with sand and gravel; it delights in Fire and autumn. Heavenly Virtue, Fortune Star, Officer Noble, Blocked Road, Great Defeat, Suspended Needle, Bent Foot. Xin Si is Self-Engendering Metal.
Complete in spirit and vital form, it withstands blazing incineration without perishing. It dreads the Fire of Bing Chen, Yi Si, and Wu Wu.
For Metal is born in Si, yet it cannot endure being brought to exhaustion and defeat in Wu, and it disperses in extinction at Yin; if it meets Fire that is flourishing and engendered anew, how could it bear it?
The Essential Discourse on the Five Elements says: "Xin Si Metal is a Self-Engendering Academy, endowed with brilliant and extraordinary virtue. In autumn and winter its efficacy is consummate; in spring and summer it brings the fortune of seven perils turned auspicious.
Entering a noble pattern, it portends heroic scholarship and conduct, advancing to pure and esteemed rank, ever cherishing a heart to succor all things."
