I have seen a few claims here and on other forums that if you meditate or get hypnosis, then the door is open for demons to come in. However, I cannot find a source for this idea. Do you really believe that quieting the mind is dangerous? If so is there a Biblical basis for this? What about our ordinary state of mental chatter? Can a demon really get through to someone who is in meditation that cannot get through when that person is worried about their to-do list, what they are going to have for dinner tonight, etc?
