"Tao" () literally means "way", but can also be interpreted as road, channel, path, doctrine, or line. In Taoism, it is "the One, which is natural, spontaneous, eternal, nameless, and indescribable. It is at once the beginning of all things and the way in which all things pursue their course." It has variously been denoted as the "flow of the universe", a "conceptually necessary ontological ground", or a demonstration of nature. The Tao also is something that individuals can find immanent in themselves.
