The ubiquitous yinyang symbol holds its roots in Taoism/Daoism, a Chinese religion and philosophy. The yin, the dark swirl, is associated with shadows, femininity, and the trough of a wave; the yang, the light swirl, represents brightness, passion and growth. John Bellaimey explains why we all contain the spirit of yin and of yang and how we can achieve a balance of both in our lives.
