Prince Wen Hui’s cook was carving up an ox. Every touch of his hand, every heave of his shoulder, every step of his foot, every thrust of his knee, with the slicing and parting of the flesh, and the zinging of the knife – all was in perfect rhythm, just like the Dance of the Mulberry Grove or a part in the Ching Shou symphony.
Prince Wen Hui remarked, “How wonderfully you have mastered your art.”
The cook laid down his knife and said, “What your servant really cares for is Tao, which goes beyond mere art. When I first began to cut up oxen, I saw nothing but oxen… I now work with my spirit, not with my eyes. My senses stop functioning and my spirit takes over. I follow the natural grain, letting the knife find its way through the many hidden openings, taking advantage of what is there, never touching a ligament or tendon, much less a main joint.
“A good cook changes his knife once a year because he cuts, while a mediocre cook has to change his every month because he hacks. I’ve had this knife of mine for nineteen years and have cut up thousands of oxen with it, and yet the edge is as if it were fresh from the grindstone. There are spaces between the joints. The blade of the knife has no thickness. That which has no thickness has plenty of room to pass through these spaces. Therefore after nineteen years my blade is as sharp as ever…”
