The primary goal of Taoism may be described as the mystical intuition of the Tao, which is the Way, the Primal Meaning, the Undivided Unity, the Ultimate Reality. Both immanent and transcendent, the Tao is the natural way of all beings, it is the nameless beginning of Heaven and Earth, and it is the mother of all things. All things depend upon the Tao, all things return to it. Yet it lies hidden, transmitting its power and perfection to all things. He who has realized the Tao has uncovered the layers of consciousness so that he arrives at pure consciousness and sees the inner truth of everything. Only one who is free of desire can apprehend the Tao, thereafter leading a life of "actionless activity." There is no Personal God in Taoism, and thus no union with Him. There are three worlds and beings within them, and worship is part of the path.
