Chapter 4, Part 9 - Chuang Tzu

When Confucius visited Ch'u, Chieh Yu, the madman of Ch'u, wandered by his gate crying, "Phoenix, phoenix, how his virtue failed! The future you cannot wait for; the past you cannot pursue. When the world has the Way, the sage succeeds; when the world is without the Way, the sage survives.

"In times like the present, we do well to escape penalty. Good fortune is light as a feather, but nobody knows how to hold it up. Misfortune is heavy as the earth, but nobody knows how to stay out of its way.

"Leave off, leave off - this teaching men virtue! Dangerous, dangerous - to mark off the ground and run! Fool, fool - don't spoil my walking! I walk a crooked way - don't step on my feet. The mountain trees do themselves harm; the grease in the torch burns itself up. The cinnamon can be eaten and so it gets cut down; the lacquer tree can be used and so it gets hacked apart. All men know the use of the useful, but nobody knows the use of the useless!"
