Is it permissible in the Shari'ah to read the books and study topics such as hypnosis as a form of treatment for ailments or to protect oneself from negative people in society who apply hypnosis in a manipulative way via language techniques. It is quite common in this time and era in business and through the media, that people use hypnotic techniques to bamboozle the thinking of an unsuspecting candidate for ulterior motives etc. A lot of modern day wizards, donning suits use it to befuddle an unsuspecting public into their agendas, via the wrong use of the field of Neuro-Linguistic-Programming etc.
