Taoism – a group of Chinese religious and philosophical traditions. Philosophical Taoism emphasizes various themes found in the Daodejing and Zhuangzi such as "nonaction" (wu wei), emptiness, detachment, receptiveness, spontaneity, the strength of softness, the relativism of human values, and the search for a long life. Religious Taoism is not clearly separated from philosophy, but incorporates a number of supernatural beliefs in gods, ghosts, ancestral spirits, and practices such as Taoist alchemy and qigong.
