The tao that can be told is not the eternal Tao The name that can be named is not the eternal Name. The unnamable is the eternally real. Naming is the origin of all particular things.

Darkness within darkness. The gateway to all understanding.
Heaven and Earth last for ever. Why do Heaven and Earth last for ever? They are unborn, so ever living. The sage stays behind, thus he is ahead. He is detached, thus at one with all. Through selfless action, he attains fulfillment.
Acting without design, occupying oneself without making a business of it, finding the great in what is small and the many in the few, repaying injury with kindness, effecting difficult things while they are easy, and managing great things in their beginnings; this is the method of Tao.
