Yin Yang Symbol - Ying Yang Sign Keychain

The Yin Yang symbol [sign] is a balancing of opposites, which goes back to ancient Chinese philosophy and religion. Yin and Yang are complementary opposites within a greater whole. Everything has both yin and yang aspects, although yin or yang elements may manifest more strongly in different objects or at different times. Yin and Yang constantly interact, never existing in absolute stasis.
