Chapter 17, Part 10C - Chuang Tzu

"But before the great turtle of the Eastern Sea had even gotten his left foot in the well his right knee was already wedged fast. He backed out and withdrew a little, and then began to describe the sea. `A distance of a thousand li cannot indicate its greatness; a depth of a thousand fathoms cannot express how deep it is. In the time of Yu there were floods for nine years out of ten, and yet its waters never rose.

"In the time of T’ang there were droughts for seven years out of eight, and yet its shores never receded. Never to alter or shift, whether for an instant or an eternity; never to advance or recede, whether the quantity of water flowing in is great or small - this is the great delight of the Eastern Sea!'

"When the frog in the caved-in well heard this, he was dumbfounded with surprise, crestfallen, and completely at a loss. Now your knowledge cannot even define the borders of right and wrong and still you try to use it to see through the words of Chuang Tzu - this is like trying to make a mosquito carry a mountain on its back or a pill bug race across the Yellow River. You will never be up to the task!
