What is Hypnosis?

Hypnosis is a state of mind , to follow , to act, to behave as per suggestions given by a person. he may get, a script, an audio stream of instructions from a person [ a hypnotist, a psychologist, a doctor or a therapist].

In short hypnosis is a suggested behaviour as per the directions, guided by any expert therapist.

Or say, all hypnosis is self hypnosis , and the degree and the depth of trance depends on how far he is allowing the suggestions , how far he is co-operating the hypnotist, how far he is believing in the influence, directions, suggestions and behaves within the range of his moral and ethical limits of his natural behaviour. He may come out of trance or influence any time , he disagree with the hypnotist.  

Who is hypnotist, hypnotherapist ?

So hypnotist or hypnotherapist is not a master, controller, governer , influencer for his patient

Hypnotherapist is simply a  guide, instructor, helper who needs the co-operation , permission, consent of the patient, to follow the suggestions from the therapist within some limit, to act and behave as per suggestions, during hypnotic influence or after the influence is over, post hypnotically..
