Query: Great Cosmic Bunk

This one is right up there with such immortal classics as "How to Fly Without Wings," "How to Jump Out of a Plane Without a Parachute," and "Brakes? Who Needs 'Em!"Sure to wreck your entire life with cliche and impossible advice written by the Masters of the Dull Adjective and Great Cosmic Repetitive Beings.If you should happen to like this book, you might also be interested in acquiring a brain tumor just to see if you can cure it by the methods listed here or standing in front of a moving bullet to test out your "Tube of Light" and "Wall of Blue Flame."Don't worry though--you shan't be disappointed to find out when you come to die that there is no such thing as the "Ascended Masters' Octave" or "The Ascension"--for dead people do not experience the least bit of surprise.
