Interestng article, Bob. I have to wonder, tho, just how many of the private individuals doing this have actual training and/or experience and I must note that the word "exorsism" is probably not accurate in most of what is being done out there. Much of it sounds like simple cleansings and blessings, not true exorcism.
Another item of note....it has been reported that the Djinn are being called in Europe. How much of the activity is now Djinn related, which many times does not respond to typical exorcism or cleansings?
