Water Phase (Shuǐ 水) — Depth, Danger, Winter

Shuǐ (水) is the phase of maximum yin, governing the North and Winter within the Wu Xing. In the shēng cycle, Water is born from Metal and gives birth to Wood; in the kè cycle, Water overcomes Fire. The Dao De Jing (Chapter 8) declares: 'The highest good is like water — it gives life to the ten thousand things and does not strive.' Water simultaneously embodies the greatest danger and the greatest beneficence, carving canyons through wu wei rather than force. Within the yin-yang framework, Water's single hidden kernel of yang within maximum yin ensures that the cycle of phases never terminates but always returns to emergence.
