I will not agree with the previous review. IMHO the person who has written it is just simply envious. I have read this book and analysed other materials of Jonathan Royle. His slightly "spade and shovel" (typical Yorkshire saying) approach for many people seem to be not politically right. And this is the best thing when you read his materials. He is really teaching valuable things explaining them from the point of view of total sceptic. He acts as if he "rejects" the existence of hypnosis and because of that approach- makes hypnosis really easy art. I have read about 140 books on hypnosis and most of them were nothing else than mumbo jumbo caused by authors "beliefs". Jonathan has changed my perception and perception of many people. Because of his knowledge I became a quite successful hypnotist in my own country. And what I know from him- works. That's it. Of course if you expect "pseudo" intellectual explanations- this book is not for you. Jonathan names things as they are- straight beteen the eyes. You may not agree to his point of view- but it does not exclude the value of knowledge offered. This author has literally saved me thousands of GPB (or dollars) I could spend on not so clear "courses" offering far less than he offers in his simple books.
We all need to understand that because of European bacground- if someone if "self promoting"... than he is perceived as "less value guy". This is the main difference between Europe and USA. This is the reason of rejecting his work by previous review.
The way Jonathan explains things may seem to "simple" or "not educated form" but who cares? Aren't you tired of "intellectual" approaches which make a huge circle around the main topic?
If you really want to learn hypnosis and are brave enough to accept his critical and sceptical point of view or even too simple language- this book and other materials by this author will dramatically improve your hypnotic work. I recommend his materials. His materials are a real gold treasure wrapped in "grey paper". I think even author himself does not know... how much valuable knowledge he offers in this book.
Simple, somethimes rough, sometimes down to earth, sometimes even offensive... but worth 10 times more than advertised on amazon.com
