Philosophical Taoism, often represented by the yin-yang symbol, emphasizes living in harmony with the Tao (the Way), or Ultimate Reality, a presence that existed before the universe was formed and which continues to guide the natural world and everything in it. Tao is the ultimate source and way (or process) of nature and the universe. To live in harmony with the Tao is to go with the flow of life rather than against it. It is a way to conserve life's vitality by not expending it in the useless ways of friction and conflict. Early Taoists perceived that the ultimate nature of this mysterious force was beyond intellectual comprehension but could be discerned by the intuitive mind. The sages observed that through meditation, one could attain Tao or communion with the way of the universe itself.
Through meditation and other devotional activities, Taoists seek to bring their lives into accord with the Tao. They believe that by abiding in the Tao, or in harmony with the Cosmos, one may attain a state of such inner clarity and insight that all actions become synchronous and spontaneously correct. They refer to this state of harmony with nature and the universe as wu wei, or "non-doing." Non-doing is not a withdrawal from action, but rather the achievement of a higher kind of action: action in accord with the natural order. The concept of wu wei more closely suggests a way of existing without conscious effort, as nature does. Such a person knows what to do by abiding in a state of quietism, by letting go of all worldly thought so that the creative force of the Tao may enter their minds and bodies. Such accord with the Tao allows one to accomplish things without effort in a way that benefits everyone.
Taoism is an inner way as well as an outward path. One should outwardly "go with the flow" while inwardly adhering to one's true nature. Taoists seek to integrate inner and outer experiences while uniting body, mind and spirit into a harmonious whole. Taoism views humanity as a microcosm of the macrocosm we call the universe. Each human being is a hologram of the Cosmos, a weaving together of universal information from a particular point of view. Essentially, we are the universe experiencing itself in human form.
Taoists equate the body with the earthly realm, the mind with the human realm, and the spirit with the heavenly realm. By bringing the body, mind and spirit into accord, one transforms personal experience and influences the interactions of the three cosmic realms. Following the Tao is a journey requiring simplicity, balance and introspection. The lifelong quest of the Taoist is to identify their innermost purpose in life, and then use every means at their disposal to achieve it.
