You move, but know not how. You are at rest, but know not why. You taste, but know not the cause. These are the operation of God's laws. How then should you get Tao so as to have it for your own?"
Cf. "Know ye not that your body is the temple of the Holy Ghost," etc. I. Corinthians vi. 19.
Confucius said to Lao Tzŭ, "To-day you are at leisure. Pray tell me about perfect Tao."

"Light is born of darkness. Classification is born of formlessness. The soul is born of Tao. The body is born of the vital essence.
Existence springs from non-existence.
"Thus all things produce after their kind. Creatures with nine channels of communication are born from the womb. Creatures with eight are born from the egg.
Nature is always self-similar.
