Check out Zen Mind, Beginner's Mind for a good book on practicing meditation. It's not religious, but basically a transcript of a Zen Master's talks on zen and the practice of meditation to his group of students. It's what I recommend to people who want to 'get' meditation.

Not specifically related to meditation, but The Tao of Pooh is still the best book I know of that deals with the concepts behind this stuff. I re-read these books whenever I lose my way, which happens more often than I'd like to admit ;)
