Yin and yang

Cosmological dualism in Chinese philosophy

Originating in ancient Chinese philosophy, yin and yang (traditional Chinese: 陰陽; simplified Chinese: 阴阳; pinyin: yīn yáng, English: ,) or yin-yang is the concept that there exist cosmic principles or forces that are opposite but complementary, which interact, interconnect, support and perpetuate each other. Together they form a dynamic system in which the whole is greater than the interdependent components, and both parts are essential for the cohesion of the whole. In Chinese mythology, the universe develops out of a primary chaos of primordial qi or material energy, organized into the cycles of yin and yang, force and motion leading to form and matter.
