Daoism, or Chinese naturalist philosophy, developed from China's prehistory. Dao translates as way, path or street. The Dao is the natural order of the universe and is interpreted through the concepts of wuji, taiji, si xiang and ba gua. Daoist ideology and inquiry into the natural world forms the basis for traditional Chinese medicine, which includes, acupuncture, herbal medicine and health exercise called qigong.
Daoist philosophy is non-contentious, and recommends allowing the events of life to unfold naturally without force. This can be observed when soft overcomes hard and yielding overcomes firm which is the basis of the martial arts Ba Gua Zhang and Taiji Quan. The metaphor widely used from the Dao De Jing, written by Lao Tze in the sixth century B.C.E. is that of water flowing over rock slowly eroding it.
The heart of Daoist philosophy is to foster the condition(s) necessary for the emergence of the whole psyche called the primordial. This is the non-dual whole mind before its fracture into self and shadow, which occurs through social and emotional conditioning. To this end Daoist philosophy engages one in self introspection and teaches different types of meditative practices.
