The Yin/Yang concept is an ancient Chinese philosophy that states that two seemingly opposite forces are actually interconnected and interdependent in the natural world. Tao, which is a three letter word, is the Chinese term for the way, path or principle. It is the fundamental concept of traditional Chinese culture and is related to the Yin/Yang concept. The Tao is the source of all things and is the ultimate reality behind the universe. It is the path of harmony and balance between the two forces of Yin and Yang.
