The knowledge of the ancients reached the highest point-the time before anything existed. This is the highest point. It is exhaustive. There is no adding to it.

The perfect man employs his mind as a mirror.

Heaven does nothing: its non-doing is its serenity. Earth does nothing: its non-doing is its rest. From the union of these two non-doings All actions proceed. All things are made. How vast, how invisible This coming-to-be! All things come from nowhere! How vast, how invisible No way to explain it! All beings in their perfection Are born of non-doing. Hence it is said: Heaven and earth do nothing Yet there is nothing they do not do. Where is the man who can attain To this non-doing?

There is danger for the eye in seeing too clearly, danger for the ear in hearing too sharply and danger to the heart from caring too greatly.

Sorrow and happiness are the heresies of virtue; joy and anger lead astray from TAO; love and hate cause loss of virtue. The heart unconscious of sorrow and happiness - that is perfect virtue. One, without change - that is perfect repose. Without any obstruction - that is the perfection of the unconditioned. Holding no relations with the external world, - that is perfection of the negative state. Without blemish of any kind, - that is the perfection of purity.

If water derives lucidity from stillness, how much more the faculties of the mind! The mind of the sage, being in repose, becomes the mirror of the universe, the speculum of all creation.

As regards the quietude of the sage, he is not quiet because quietness is said to be good. He is quiet because the multitude of things cannot disturb his quietude. When water is still, one's beard and eyelashes are reflected in it. A skilled carpenter uses it in a level to obtain a measurement. If still water is so clear, how much more are the mental faculties! The mind of the sage is the mirror of heaven and earth in which all things are reflected.
