Chapter 24, Part 6 - Chuang Tzu

Chuang Tzu was accompanying a funeral when he passed by the grave of Hui Tzu. Turning to his attendants, he said, "There was once a plasterer who, if he got a speck of mud on the tip of his nose no thicker than a fly's wing, would get his friend Carpenter Shih to slice it off for him. Carpenter Shih, whirling his hatchet with a noise like the wind, would accept the assignment and proceed to slice, removing every bit of mud without injury to the nose, while the plasterer just stood there completely unperturbed.

Lord Yuan of Sung, hearing of this feat, summoned Carpenter Shih and said, `Could you try performing it for me?' But Carpenter Shih replied, `It's true that I was once able to slice like that - but the material I worked on has been dead these many years.' Since you died, Master Hui, I have had no material to work on. There's no one I can talk to any more."
