"What the manipulators say...
It's interesting that many cult leaders will often claim that people cannot be made to do things against their will, even using mind control hypnosis. There are two important issues here.
First of all, the members of the group are programmed to accept whatever the leader says. Therefore they will tend to accept this idea. Secondly, implicit in the idea is that if the person does something they are doing it of their own volition; it is their own decision to do so. When we make our own decisions, we believe more firmly and are more committed to the result, and the actions and effects of our decisions last longer. This is a very subtle but potent idea."
"When people are bored or tired, they will often find their attention drifting internally, away from the outside world. It is often easier to induce hypnosis in people like this, or for the unscrupulous hypnotist or cult leader to utilize these naturally occurring trances to implant suggestions in people. And remember, in cults and sects the suggestions given using the combination of mind control hypnosis are for the leaders benefit!
Group pressure is another powerful force for getting people into trance states. If everyone around you is doing the same thing, it can be very difficult not to follow along, especially if the group leader is berating anyone for being different!"
