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.
Exorcist II: The Heretic
Father Lamont visits the institute, but his attempts to question Regan about the circumstances of Father Merrin's death are rebuffed by Dr. Tuskin, who believes that Lamont's approach would do Regan more harm than good. In an attempt to plumb her memories of the exorcism, and specifically the circumstances in which Merrin died, Dr. Tuskin hypnotizes the girl, to whom she is linked by a "synchronizer", a revolutionary biofeedback device used by two people to synchronize their brainwaves. After a guided tour by Sharon of the Georgetown house where the exorcism took place, Lamont returns to be coupled with Regan by the synchronizer. The priest is spirited to the past by Pazuzu to observe Father Merrin exorcising a young boy, Kokumo, in Africa. Learning that the boy developed special powers to fight Pazuzu, who appears as a swarm of locusts, Lamont journeys to Africa, defying his superior, to seek help from the adult Kokumo.
