" The Tao is the ultimate truth and substance of life. It is what all of humanity’s spiritual seekers have
been pursuing, and it is complete oneness. It is the principle of life energy flowing behind all things in the cosmos, and it is the ultimate wholeness to which all things, on becoming one, return. Although it is all things in existence, the Tao is also the source and background that causes them to exist. "
