Prince Wen-hui's cook, Ting, was cutting up an ox. Every touch of his hand, every ripple of his shoulders, every step of his feet, every thrust of his knees, every cut of his knife, was in perfect harmony, like the dance of the Mulberry Grove, like the chords of the Lynx Head music. Well done! said the prince. How did you gain such skill? Putting down his knife, Ting said, I follow the Tao, Your Highness, which goes beyond all skills. When I first began cutting up oxen, all I could see was the ox. After three years, I had learned to look beyond the ox. Nowadays I see with my whole being, not with my eyes. I sense the natural lines, and my knife slides through by itself, never touching a joint, much less a bone. A good cook changes knives once a year: he cuts. An ordinary cook changes knives once a month: he hacks. This knife of mine has lasted for nineteen years; it has cut up thousands of oxen, but its blade is as sharp as if it were new. Between the joints there are spaces, and the blade has no thickness. Having no thickness, it slips right through; there's more than enough room for it. And when I come to a difficult part, I slow down, I focus my attention, I barely move, the knife finds its way, until suddenly the flesh falls apart on its own. I stand there and let the joy of the work fill me. Then I wipe the blade clean and put it away. Bravo! cried the prince. From the words of this cook, I have learned how to live my life.
