What religion uses the yin yang symbols?

The yin yang is the easily recognized Taoist symbol of the interplay of forces in the universe. In Chinese philosophy, yin and yang represent the two primal cosmic forces in the universe. Yin (moon) is the receptive, passive, cold female force. Yang (sun) is masculine- force, movement, heat. The Yin Yang symbol represents the idealized harmony of these forces; equilibrium in the universe. In ancient Taoist texts, white and black represent enlightenment and ignorance, respectively.
