Sanming TonghuiVol. 1, On the Nature and Fortune of the Sixty Jiazi (verdicts & remarks)
Jia Shen Water is a sweet well; it delights in spring and summer. Broken Salary and Horse, Blocked Road, Flat Head, Broken Character, Suspended Needle. Jia Shen is Self-Engendering Water. Its flow is expansive, and it benefits from containment and order.
It also borrows birth from Metal and does not dread abundant Earth, though it particularly disdains the Earth of Wu Shen and Geng Zi.
The Essential Discourse on the Five Elements says: "Jia Shen Water is self-engendering and holds the Innate Academy; one who has it in their arrangement is endowed with sharp intelligence and wisdom, yielding boundless marvelous utility."
