You need a hell of a lot of spirit to read the Dictionary.

Whenever I go to Barnes & Noble, I always browse that section, too bad I don't log any of the information into my memory banks.

The most spiritual book I've read is "The Celestine Prophecy", but if you view "The Bible" as a spiritual book, it will make it a lot easier to understand (and believe), as well as probably the best spiritual book. The connection made through milleniums, with The Bible, is, only, a spiritual connection.
