The aim of this book seems to be to convince us how evil hypnosis is. The author has apparently come to this conclusion after training and practising for several years as a hypnotherapist, then when that proved to be not very lucrative, moving on to being a stage hypnotist.
This is supposedly an autobiography detailing the author's own experiences and views, which don't seem to be supported by any meaningful evidence. His views seem to include the belief that a high proportion of hypnotherapists commit suicide, despite being advised to the contrary by the organisation that awarded him his doctorate; that many people who undergo hypnosis become psychotic, whilst providing no evidence to back up this claim; that hypnosis is a "morbid negative condition" (contrary to widespread medical opinion) that can lead to a state where "brain cells have become deranged" (psycho-babble).
In the first part of the book where he talks about his training as a hypnotherapist (and his belief that he might have been hypnotised into doing this), he explains that there is no formal qualification required to become a hypnotherapist, and that whilst the doctorate that he was awarded by a school of hypnotherapy and parapsychology based in Malta allows him to legally use the title Doctor in the UK, it is basically meaningless as it has no academic or medical accredition. It seems rather cynical in my view to publish this book under the name "Dr" Jeremy Wheeler, so giving the impression that the book has gravitas, when he says himself "my doctorate of hypnosis is a joke really".
The last couple of chapters switch from telling us how evil hypnosis is to telling us how wonderful ancient wisdom is: we are treated to discourses on aura, chakras, and cosmic consciousness amongst other things.
In my opinion, the book rambles on and makes outlandish claims without justifying any of them, and it reads like a conspiracy theory. I would suggest that if you want to get a rational, informed view of hypnosis and hynotherapy, you should move on quickly.
