Know Your Magnetic Field, by William E. Gray

"One of the mainstays of New Thought has been the concept that diseases can be healed using mental abilities inherent in everyone. This short book describes one view of the mechanics of this in simple terms. This is far outside what conventional medicine believes to be effective, and obviously using this as a first resort would be unwise. However, it is today possible to find practicioners of this method, or something similar, in the phone book in most large cities. At the worst, the techniques described here appear to be harmless."
