SELF-PROCLIMED exorcist Bob Larson could be using hypnosis to entrance his subjects, an expert says. Melbourne counseling hypnotherapist Daryl Wilkinson says the techniques used by the US evangelist are typical of hypnotherapy. "Basically what he's doing is a selection process, seeing who is susceptible to suggestion," he said. Larson performed several exorcisims and blessings before hundreds of mostly young people at a free sermon at the Forum Theatre on Friday night.... "If someone is wide-eyed and into it, he'll take them, but if someone is 'Oh yeah, c'mon, he won't." Mr Wilkinson said.
