I just read 3 books on self hypnosis so I can show you a little comparison: - 50 self-hypnosis exercises is a very successful work. Coverage left me thinking about a gimmick book. But in reality it is the most practical book, the more pragmatic and more usable. And respect fully all aspects of self-hypnosis. Nothing is missing, pleasantly surprised !!! - Self-hypnosis Finel Kevin is more difficult to use. Me it did not allow me to return to self hypnosis at all. By cons, he brings something that is totally absent from the other 2. This is the explanation of the potential of hypnosis. Even if sometimes he goes too far for my taste. It offers us to use self-hypnosis all day and in all situations. In this case I want to say "but why not show us concrete examples of people already do." And without these examples, it remains only an opinion. But it opens our minds to a whole potential fields, so as indispensable as 50 self-hypnosis exercises. Just a tip, cover with stars it's been so clairvoyance, spirituality it serves the moidernité of what is inside the book. - Self-hypnosis - For Beginners Olivier Lockert is totally disappointing. It was published after the 2 others. So, I expect to have something even better. This book is useless compared to the other two. Honestly, I would have played first, I would have found it. But as I read after the other 2, this book is useless compared to the other two. In addition, the practice of hypnosis seems a bit dated by presenting induction techniques by candlelight or metronome. In addition to printing the book and unpleasant. The letters are driven into the binding which requires quartered each page.
