input: posthypnotic suggestion [Pentecostalism] This is seen often in Pentecostal churches. The audience is trained so that when the faith healer says or does certain things, the result is slaying in the Spirit. One faith healer turned the slew the entire choir, except for an old deaf man who didn't HEAR the cue!!!
output: Possibly the surest way to obtain instantaneous hypnosis is to give the hypnotized subject a posthypnotic suggestion that when you do such and such he will immediately become hypnotized. The "such and such" can be any cue desired. A simple one would be to suggest: "When I look into your eyes and tell you to 'GO TO SLEEP' you will instantly become hypnotized. The subject is then awakened. You can then test the response. Passing by the subject, suddenly turn and look in his eyes and forcefully state: 'GO TO SLEEP.' Immediately hypnosis is induced.
