Chapter 24, Part 14B - Chuang Tzu

Kou-chien, with his three thousand men in armor and shield, took up his position at K'uai-chi; at that time Chung alone was able to understand how a perishing state can be saved, but he alone did not understand how the body may be brought to grief. Therefore it is said, The owl's eyes have their special aptness, the stork's legs have their proper proportions; to try to cut away anything would make the creatures sad.

It is said, When the wind passes over it, the river loses something; when the sun passes over it, it loses something. But even if we asked the wind and sun to remain constantly over the river, the river would not regard this as the beginning of any real trouble for itself - it relies upon the springs that feed it and goes on its way. The water sticks close by the land, the shadow sticks close by the form, things stick close by things.

Therefore keen sight may be a danger to the eye, sharp hear­ing may be a danger to the ear, and the pursuit of thought may be a danger to the mind. All the faculties that are stored up in man are a potential source of danger, and if this danger becomes real and is not averted, misfortunes will go on piling up in increasing number.

A return to the original condition takes effort, its accomplishment takes time. And yet men look upon these faculties as their treasures - is it not sad? Therefore we have this endless destruction of states and slaughter of the people - because no one knows enough to ask about This!
