Daoism originated in China over 2,000 years ago and emphasizes living in harmony with the Dao (also spelled Tao), which is the natural or divine order of the universe. Some key beliefs and concepts in Daoism include Yin and Yang, the balance of opposing but complementary forces; Qi or vital energy that flows through all things; and Wu Wei, action through inaction. Daoism also teaches that one should embrace humility, spontaneity and non-interference with the natural way of things. Daoist scriptures include the Dao De Jing and the Zhuangzi, and symbols of Daoism include the Yin Yang symbol representing balance.
