水 Sui or mizu, meaning “Water”, represents the fluid, flowing, formless things in the world. Outside of the obvious example of rivers and the lake, plants are also categorized under sui, as they adapt to their environment, growing and changing according to the direction of the sun and the changing seasons. Blood and other bodily fluids are represented by sui, as are mental or emotional tendencies towards adaptation and change. Sui can be associated with emotion, defensiveness, adaptability, flexibility, suppleness, and magnetism.
