This quintessential work should be obligatory study for anyone in the field of Hypnotherapy. Donald Robertson unfolds the history of this most powerful therapy, through the words and works, the experiments and demonstrations, of Dr. James Braid, in a straightforward, deeply educational and most enlightening fashion. Excellently researched, it recounts the journey of a highly respected doctor who set out to debunk the follies of Mesmerism and found the jewel of Hypnosis. If you wish to simply understand hypnosis, or study the subject in depth, this is most certainly the book to have. I would go so far as to say, shame on anyone in the field of Cognitive Behavioural Hypnotherapy, who remains ignorant of what this book contains.
