Query: Simple Yes, Powerful No

Don't waste your money on these "sensational" "simple" "powerful" books. The information in these books can basically be found online using the keywords "meditation techniques". The book makes numerous authoritative claims and implies the information comes from God, but these claims appear to come more from the author's ego than God's mouth. The piece de resistance of the book is the "powerful" technique called "running energy"--again, this is something easy to find online. Not only that, but the writer seems to assume all readers IQ's average 70. A complete waste of time and money.For a couple of great books about this subject, try "Cosmic Consciousness" by Dr. Richard M. Bucke or "The Power of Now" by Eckhart Tolle.
