Okay, I have answered my own question as there is some history: [
en.wikipedia.org]
Still, other than the usual sort of group hypnosis and the occassional weird and unexplainable phenomena that sometimes occurs at Charismatic meetings, are people being bilked, manipulated, or abused in any way? Has a cult grown up around these meetings?
The reason I ask is that I know somebody who seems to have been quite disturbed (dare I say damaged) by a long association with a group of holy rollers and I would like to know more about how it works from the inside, if you are privy to that.
