Some performed the duties but changed faith after that so that they dun do it any more.

I am not sure whether the setbacks are destined or "created".
Spirits aka jinns are just like humans. There are Chinese Malay Indian etc race. They can possess human/race. Thay can speaks tongue too. So bomoh also can be a tangki.
