Books such as The Alchemist, Conversations with God and yes, The Secret have all served to increase my curiousity of all things spiritual.
I just searched the for the book you mentioned. It doesnt appear to be available yet, but the trailer is incredibly powerful and very moving. If the book captures even a quarter of that, it will be the next big thing.
I also agree with Talisman about living it. Wisdom equals knowledge applied to action.
Thanks for encouaging this dialogue. I'm reserving my copy now.
