We join spokes together in a wheel, but it is the center hole that makes the wagon move. We shape clay into a pot, but it is the emptiness inside that holds whatever we want. We hammer wood for a house, but it is the inner space that makes it livable. We work with being, but non-being is what we use.
Without going out-of-doors, one can know all he needs to know. Without even looking out of his window, one can grasp the nature of everything. Without going beyond his own nature, one can achieve ultimate wisdom. Therefore, the intelligent man knows all he needs to know without going away, And sees all he needs to see without looking elsewhere, And does all he needs to do wihout undue exertion.

What is a good man but a bad man's teacher? What is a bad man but a good man's job? If you do not remember this, You will get lost, No matter how intelligent you are. It is the great secret.
The Great Tao flows everywhere, to the left and to the right, all things depend on it to exist, and it does not abandon them. To its accomplishments it lays no claims. It loves and nourished all things, but does not lord it over them.
