"Every sound is born out of silence, dies back into silence, and during its life span, is surrounded by silence. Silence enables the sound to be."

These two aren't from a book, but I still think they're great:

"Nothing in life will ever be bigger or smaller than your thoughts about it. This is the battle between you and yourself."

"You immerse yourself in whatever it is, and you become that, and give yourself no way out."
