Someone posted a 1988 video of David Calof doing a hypnotic induction. It's great (except for the video quality) and has links to several other hypnosis-related videos. I learned hypnotic techniques in the early 80's, at the beginning of my career, and find myself using hypnotic language, voice tones, and anchoring techniques in many sessions. Here's the url for the video: http://www.youtube.com/watch?v=81rZe2wuWxY .
David is a master, enjoy it!
