Chapter 1, Part 4 - Lieh Tzu

On one hand, there is life, and on the other, there is that which produces life; there is form, and there is that which imparts form; there is sound, and there is that which causes sound; there is colour, and there is that which causes colour; there is taste, and there is that which causes taste.

Things that have been endowed with life die; but that which produces life itself never comes to an end. The origin of form is matter; but that which imparts form has no material existence. The genesis of sound lies in the sense of hearing; but that which causes sound is never audible to the ear. The source of colour is vision; but that which produces colour never manifests itself to the eye. The origin of taste lies in the palate; but that which causes taste is never perceived by that sense. All these phenomena are functions of the principle of Inaction.

To be at will either bright or obscure, soft or hard, short or long, round or square, alive or dead, hot or cold, buoyant or sinking, treble or bass, present or absent, black or white, sweet or bitter, fetid or fragrant -- this it is to be devoid of knowledge, yet all-knowing, destitute of power, yet all-powerful.

Such is Tao.
~ Lionel Giles translation via Terebess Asia Online ~
