The religion of hinduism says that if you've been bad, you may come back as a rat or some other animal. If you've been good, you might come back as a prince. But that's like someone saying, when you jump out of the plane, you'll get sucked back in as another passenger. If you've been bad, you go down to the Economy Class; if you've been good, you go up to First Class. It's an interesting concept, but it doesn't deal with your real problem of having sinned against God and the reality of hell.
