[Sunil_M88]

Forgot to ask, what's the reasoning behind certain people getting possessed by God during religions ceremonies and functions. I've witnessed this during Gujarati Garba outings during Navratri. My granddad, who was a monothiest Hindu before only worshiping shiv ji (yet he had his friend read him the bhagvad gita before passing away), used to shun these people as being pakhandis (attention seekers)
