Why Hindu follower allowed them self posses by spirit then act like a crazy person hu

What would happen if someone sprinkle holy water on the person that has been pissed. And read christian prayer on them

Hindu?
What you're describing sounds more like Voodoo. Hinduism is just another polytheistic religion, but there's no spirit possessions that I've heard about.
Now Voodoo on the other hand does have spirit possession; it is a ritual where the 'priest' invokes a deity so that that deity may speak through him. This is typically accomplished by music, wild dancing (psychodrama).

Any religious person can still be possessed. I've heard Christians and Jews become possessed. My best friend who is Jewish in her late teens was always possessed and her parents were devout Jews.

So this "Hindu" thing you are saying has nothing to do with the possession. It has to do with the individual themselves regardless of their religion, background, upbringing, culture, etc.

It sounds like you are trying to make yourself believe that Christians are superior to Hindu's. A question like this only confirms your ignorance.

Your bias is classic. Get some education, now.

Really what is your problem with Hindus?

Afraid of their deep philosophical thoughts?

Are they are not converting to your beliefs fast enough?

Will it work if I sprinkle some of that holy water on you along with a prayer to Christ? Will anti Hindu sentiments which possess you will leave you alone and let your brains take hold again?

that Satan inspired.

God works in mysterious ways. Love the Hindu. Have a great day.

Holy water is only "holy" because it has been blessed by a holy person. If you live a holy life you too can bless water, or other objects. Holy water has no effect on those who do not appreciate the worth of its holiness.

You'd love to say these things at work. Probably best not to though.

Where does it say only Hindus get possessed by spirits or whatever?

I see it on western television all the time. THere are very serious problems of this in America. I think Sylvia Brown and others who come on television are always doing this kind of work.

I never saw evidence of this.

Demon possession is like drug addiction. The DEMONS make it SOOOOOOOO ATTRACTIVE. Like a CRACK or HEROIN or MARIJUANA addiction! They are SNEEKY and deviate in tricking people into things. The Devil, in the BEGINNING took a SMALL LIIIIIEEEEEEEEE and made a MESS of the WORLD today! Don't fall for any TRICKS of ATTRACTION!!!

To answer your question - nothing.

he will dance like a mad bull or cow

I think if you read the Bible you will find that Jesus once said some evil spirits are so strong, that they cannot be cast out except by Priesthood authority combined with fasting and prayer. You have to be careful not to judge people who have seizures or Tourettes syndrome. You did not describe how you thought the person was hurting themselves, so that is why I would be careful. I have know men in the Church of Jesus Christ of Latter-day Saints who have the Priesthood of Jesus Christ who have cast out evil spirits before, but I have not seen it in front of me. Have a good day.

I have found that every time I've heard of someone being "possessed" they were actually just someone craving attention.

I am a Buddhist, and in general, I don't believe in demonic possession.

If someone believes that allowing himself to be possessed by a spirit is part of their spirituality, and they WANT to do it, (as is often the case in Voodoo... a CHRISTIAN religion...) then you have no right to interfere.

Or perhaps I should run in and disrupt the holy sacrament, because drinking blood taints your soul?

what is the question??
