Chapter 12, Part 11B - Chuang Tzu

The gardener flushed with anger and then said with a laugh, "I've heard my teacher say, where there are machines, there are bound to be machine worries; where there are machine worries, there are bound to be machine hearts. With a machine heart in your breast, you've spoiled what was pure and simple; and without the pure and simple, the life of the spirit knows no rest. Where the life of the spirit knows no rest, the Way will cease to buoy you up. It's not that I don't know about your machine - I would be ashamed to use it!"

Tzu-kung blushed with chagrin, looked down, and made no reply. After a while, the gardener said, "Who are you, anyway?"

"A disciple of Kung Ch'iu."

"Oh - then you must be one of those who broaden their learning in order to ape the sages, heaping absurd nonsense on the crowd, plucking the strings and singing sad songs all by yourself in hopes of buying fame in the world! You would do best to forget your spirit and breath, break up your body and limbs - then you might be able to get somewhere. You don't even know how to look after your own body - how do you have any time to think about looking after the world! On your way now! Don't interfere with my work!"

Tzu-kung frowned and the color drained from his face. Dazed and rattled, he couldn't seem to pull himself together, and it was only after he had walked on for some thirty li that he began to recover.
