Have you read this book? You should.
(For my money I would avoid Barry Green's Inner Game of Music. The original is better, in my opinion.)
Here's a nice paragraph...
"The image comes to my mind of the balanced movement of a cat stalking a bird. Effortlessly alert, he crouches, gathering his relaxed muscles for the spring. No thinking about when to jump or how he will push off with his hind legs to attain the proper distance, his mind is still and perfectly concentrated on his prey. No thought flashes into his consciousness of the possibility or consequences of missing his mark. He sees only the bird. Suddenly the bird takes off; at the same instant, the cat leaps. with perfect anticipation he intercepts his dinner two feet off the ground. Perfectly, thoughtlessly executed action, and afterward, no self-congratulations, just the reward inherent in his action: the bird in the mouth."
