The Zen Book — Daniel Levin

The zen mind is the beginner's mind, which sees everything as if for the first time. It is in this zen mind that realization comes. People sit for many years in meditation to find that suddenly in hearing something again for the first time, they're lifted to a state of understanding that's far beyond anything they've ever experienced. This is why the sayings in this book were written. They're not meant to teach, but rather to remind you of things you already know.
