Which religion or set of beliefs stresses living simply and in harmony with nature?

Taoism, also known as Daoism, is a religious or philosophical tradition of Chinese origin which emphasizes living in harmony with the Tao (literally "Way", also romanized as Dao). The Tao is a fundamental idea in most Chinese philosophical schools; in Taoism, however, it denotes the principle that is both the source, pattern and substance of everything that exists with emphasis to nature.
