Hrm. I've read a LOT of books. Many have changed my views on something or other, but nothing is coming to mind. Instead I'll tell you a funny story about a book I still have yet to read.
I was taking a CranioSacral course with my friend Molly and during a break we were walking around the book section finding ways to spend money we didn't have. I randomly picked up a book called Healing your rift with God and tossed it aside, saying "I don't have a stinking rift with GOD" and moved on. Molly laughed at me and we went about our way.
Six month and much personal shift later, Molly and I were at another CST training and perusing the books again when I picked up the same book. Apparently I had no memory of disdaining the book before and exclaimed to Mol, "Oh my God! I totally NEED this book!" She had quite a laugh, and I bought the book.
Here it is several years later, and I have yet to read the book, and truth be told, I still have quite a rift with God, one that has turned more into a chasm in recent years. But that is a post for another question, no?
