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.
Exorcism in Islam
Possession is not caused by Satan, who is said to be just a tempter, whispering evil suggestions into humans heart, but, even though not mentioned in canonical scriptures, according to folklore by jinn, who can enter a human body physically or haunting them mentally. A possession by a jinn can happen for various reasons. Ibn Taymiyyah explained a Jinn could sometimes haunt an individual, because the person could (even unintentionally) harm the jinn; urinating or throwing hot water on it, or even killing a related jinn without even realizing it. In this case the jinn will try to take revenge on the person. Another cause for jinn possession is when a jinn falls in love with a human and thereupon the jinn possesses the human. Some women have told of their experiences with jinn possession; where the jinn tried to have sexual interaction from inside their bodies. Thirdly, it occurs when a jinn is evil and simply wants to harm a human for no specific reason, it will possess that person, if it gets the opportunity, while the human is in a very emotional state or unconsciousness. Jinn may also haunt someone in service of a sorcerer.
