This book is fun and easy to read. It has a wide selection of suggestibility tests, inductions and routines for stage hypnosis. It does not deal with therapeutic aspects of hypnosis.
Even if you're not interested in stage hypnosis, you can still benefit from learning suggestibility tests and inductions. Using suggestibility tests will make a great difference when you're using hypnosis on others because they help you to discover the level of rapport you have with the person, the person's willingness and ability to use his imagination, and they also serve as "convicers" for the person that he has been "hypnotized", making the person more receptive to further suggestions. In the end, suggestibility tests, determine the person's willingness to play along at any given time. If they are not in mood to play along at one time, they may be in better mood to play along at some other time - so you don't need to make any definite conclusions regarding the hypnotizability of a particular person. Everyone is hypnotizable - just different people may prefer to get into a trance in a different ways at different times.
The book continues with different inductions and deepeners you can use. It's good to experiment with all of them as they can all come in handy at some point. The variety of methods will also keep learning hypnosis fun.
After the section of routines you can do in stage hypnosis, there is a small section of self-hypnosis - how you can use hypnosis to deal with some common issues. There is much more both to stage hypnosis, and to applications of hypnosis, so when you're finished with this book - keep learning.
When you're done with this book, if you want to learn more about "stage hypnosis" get Ormond McGill's Encyclopedia of Hypnosis.
