Buzzsay, I believe you could be right on the mark with your assessment that the hindu is possessed with a demon. After all, there are many tens of thousands of fallen angels, aka "demons" trapped here on earth. Where are they? They are up to all sorts of mischief as they serve Satan. So, keep up your good work, and keep your (our) faith in Christ. Do not let their godless mocking ever get to you.
