The yin yang meaning and symbol date back to ancient China and represent the belief that everything in the universe consists of two forces that are opposing but complementary.
According to yin yang philosophy the universe, and everything in it, is both constant and cyclical. One force dominates and then it is replaced by the opposing force. This activity continues constantly and repeats itself over time. Examples illustrating the philosophy of yin yang include:
Together the black and white areas represent the interaction of the energies found in all things. They illustrate the cyclical nature yin and yang and all that it represents.
Located in the areas of their opposite colors, the small circles show that nothing is absolute. In each of the opposing forces there is a small part of the other. In all yin there is yang and in all yang there is yin. This holds true for everything in the universe, for example in every female there is a little male and in every good there is a little evil. Nothing in the universe, or in life, is simple black or white. Each exists in the other and each needs the other to exist.
