Water (☵) — Abysmal

One yang line between two yin — danger, depth, the force that finds the lowest path. Water is the middle son, the abysmal principle, the element that doesn't retreat from obstacles but flows around, beneath, and through them. It appears in fifteen hexagrams, carrying qualities of danger, sincerity, and the persistence that outlasts obstruction. Where yang is trapped between yin, the energy seeks its own release.
