The monks are Kwan Im are used to such events. Sometimes relatives or friends bring them down. When someone behaves likes this for such a long period, its not drug induced. Policemen have thrown people in diabetic coma into lock-up only to find a dead body the next day.
I know of a lady in the UK, who brought her son here on the pretext of having a family holiday. When one is desperate and when conventional means does not help . One would try anything.
Just a clarification. The "priests" involved are not from the temple. From what I understand, they are associated with the temple because they provide some kind of service for temple go-ers from outside the temple. If anyone have been to the temple, you would certainly have noticed there are alot of "priests" hanging outside with an array of religious services.
I was very surprised when the paper ran the story and claim it was the temple's monks that perform exorcism. I have visited this temple before and my understanding is that they do not provide such services. Hope the paper can clarify this. Seems like a desperate attempt to grab headlines.
