The Four Agreements, by Don Miguel Ruiz; subtitlted something like "Toltec Wisdom". Mr. Ruiz is a Toltec Indian. It's a small book that can be read easily in an afternoon but you will think about it long after. If you're looking for a little spiritual nourishment/encouragment/AND challenge, and you've already read the Bible and you're sick of all the New Age crap like so much diarrhea, try this one, I think you'll get a lot out of it. Anyway, otherwise have a great Holy-Day.
