In my opinion, the hypnotist must firstly be a person of the highest integrity, who is ever a- ware of his responsibilities to his clients. He must be firm ly grounded in the study and under standing of psychology and its techniques; of affable address; of sympathetic attitude; of pleas ant and reassuring manner; calm understanding and patience; so that the total impression of his personality, inevitably creates the favorable rap port that is so essential to the success of the able hypnotist. Thehypnotistmustaboveallhavecom plete confidence in himself and his technical ef ficiency, since to be effective, it is necessary that he speak with the surest authority, so that he can control the subject completely.
