Burmese folk religion
These exorcists, or "ahletan hsaya", are said to possess powers that can fend away or challenge these evil demons. These exorcists were often seen as very holy, because they had to be to combat troublesome spirits. They attempt exorcisms by giving the nat offerings. As an interesting overlap with Buddhism, exorcisms can be performed by holding the Buddha up to the possessed person, in an effort to have the Nat flee. If the exorcist cannot banish this spirit alone, they often ask for the assistance of the nat-kadaw. Sorcerers, or "weikzas" also harnessed the power of these nats through many complex rituals, to gain their own supernatural powers.
Gabriele Amorth
Amorth was also interviewed for the second episode of "True Horror with Anthony Head", presented by Anthony Head. He explained he would never perform an exorcism based solely on someone's claims of possession; always directs people to psychiatrists and doctors first, and that when he sees someone is not possessed but the person still insists, he replies: "You have no devil. If you have a problem, talk to a good vet."
