The first thing you have to do in a Hindu temple is take your shoes off. I think it's the same in the other religions from India and Pakistan. You have to sit on the floor and it's a way of keeping a temple special. You have to take your shoes off in a mosque. It's a rule to do with keeping it clean I suppose, you leave off your outside shoes. Muslims also have to wash their hands and their mouths before they pray, so you'll always find somewhere to do that.
