The fourth principle, asymmetry, is in some ways a continuation of the yin-yang. Asymmetry stresses the abstract and ever-changing nature of everything around us. This aesthetic principle is largely representative of the Buddhist principle of Wabi-sabi, which states that all things are imperfect, irregular, and impermanent. This principle is shown in the garden through the winding pathways, stones of many different sizes, and abstract placements of objects. Additionally, the changing of the waves in the dry Zen Garden is a tradition that honors wabi-sabi.
