Taoism (), or Daoism (), is a philosophical tradition of Chinese origin which emphasizes living in harmony with the "Tao" (, or "Dao"). The "Tao" is a fundamental idea in most Chinese philosophical schools; in Taoism, however, it denotes the principle that is the source, pattern and substance of everything that exists. Taoism differs from Confucianism by not emphasizing rigid rituals and social order, but is similar in the sense that it is a teaching about the various disciplines for achieving "perfection" by becoming one with the unplanned rhythms of the universe called "the way" or "tao." Taoist ethics vary depending on the particular school, but in general tend to emphasize "wu wei" (action without intention), "naturalness", simplicity, spontaneity and the Three Treasures: , "compassion", , "frugality" and , "humility".
