Chapter 17, Part 10D - Chuang Tzu

"He whose understanding cannot grasp these minute and subtle words, but is only fit to win some temporary gain - is he not like the frog in the caved-in well?

"Chuang Tzu, now - at this very moment he is treading the Yellow Springs or leaping up to the vast blue. To him there is no north or south - in utter freedom he dissolves himself in the four directions and drowns himself in the unfathomable. To him there is no east or west - he begins in the Dark Obscurity and returns to the Great Thoroughfare.

"Now you come niggling along and try to spy him out or fix some name to him, but this is like using a tube to scan the sky or an awl to measure the depth of the earth - the instrument is too small, is it not?

"You'd better be on your way! Or perhaps you've never heard about the young boy of Shou-ling who went to learn the Han-tan Walk. He hadn't mastered what the Han-tan people had to teach him when he forgot his old way of walking, so that he had to crawl all the way back home. Now if you don't get on your way, you're likely to forget what you knew before and be out of a job!"

Kung-sun Lung's mouth fell open and wouldn't stay closed. His tongue stuck to the roof of his mouth and wouldn't come down. In the end he broke into a run and fled.
