This is perhaps one of the best book in support of hypnotherapy with many anecdotal stories and explicit exercises for practicing hypnotherapy.
The book provides a step-by-step guide on how an amateur hypnotist can bring their client into a trance by speaking at a pace that matches the client's breathing, using nonspecific languages, overloading the client's senses, and most importantly, speak with complete congruency.
The following quote works splendidly in convincing me of the use case of hypnotherapy:
"let me ask you a question. If that door were to burst open right now . . . and you looked over and saw a great big tiger . . . licking its chops hungrily . . . staring at only you . . . how much pain do you think you'd feel?" For most people, it doesn’t even take an emergency, they just need to be distracted by something"
15 topics with many concrete exercise and explicit examples:
Verbal pacing and leading, overlapping representational systems, leveraging inductions and pattern interruption, overloading, personal power, slacking realities, techniques for dealing with abreactions, reframing, setting up unconscious signals, deep trance identification, pain control, regression, amnesia, congruency, and even self-hypnosis.
If you could only read one book on hypnosis, I would recommend this book.
