Yin (阴, Yīn)/Yang (阳, Yánɡ)

I Ching (易经, YìJīnɡ) illuminates the principles of the Tao, the universal flow that underlies all action and permeates all being. These principles are most easily measured in the material world by yin (阴, Yīn) and Yang (阳, Yánɡ), the polar opposites. It is the degree of yin and yang present in each of the 64 situations that defines it.

Each polarity helps define a situation, action, or being with its own respective traits, some of which are listed below.
