Well, it’s worth a try. Straight ahead talk on mental techniques for any kind of ailment, illness or life threatening disease. The author is not lettered scientist, apparently, which might raise a concern that he’s not qualified to be writing on this topic, but having read so many health enhancement books by doctors and scientists, one finds these most advanced certificates interfere often with the writing. In short, experts talk too much. This author is concise and poignant, I read the entire book over one breakfast.
Well, I’d say give it a go, do the visualizations, nothing to lose. Note he never suggests forgoing conventional medical treatment, only that the mind plays a strongly influential role in how the body responds to physical (and obviously also psychological) problems so you’ld be well advise to make use of it.
