Taoism (or Daoism) is a philosophical, ethical, and religious tradition of Chinese origin that emphasizes living in harmony with the Tao (also romanized as Dao). The term Tao means "way", "path" or "principle", and can also be found in Chinese philosophies and religions other than Taoism. In Taoism, however, Tao denotes something that is both the source and the driving force behind everything that exists.
