Tao Te Ching 4

The Tao is like the emptiness of a vessel; and in our employment of it we must be on our guard against all fullness. How deep and unfathomable it is, as if it were the Honored Ancestor of all things!

We should blunt our sharp points, and unravel the complications of things; we should attemper our brightness, and bring ourselves into agreement with the obscurity of others. How pure and still the Tao is, as if it would ever so continue!

I do not know whose son it is. It might appear to have been before God.
