The Tao gives birth to One. One gives birth to yin and yang. Yin and yang give birth to all things... The complete whole is the complete whole. So also is any part the complete whole... But forget about understanding and harmonizing and making all things one. The universe is already a harmonious oneness; just realize it.
LaoziThe one who is conscious (in Tao) can't speak. The one who can speak is not conscious (centered in Tao)
