Yeah. As said, Hinus and Buddhists try and free themselves the eternal struggle and achieve moksha or nirvana. Howeber, I believe that Mahayana Buddhists (something like that) hold more secular beliefs and believe that only the great Buddha himself was holy enough achieve nirvana. The only way to free oneself from the eternal struggle is to pony up the cash to the monastary, hehe.
The Earth is the closest thing to hell in the two religions although someone mentioned demons in one form of Buddhism. That's probably true as Buddhism is much more cosmopolitan and has less of a central identity. You could probably find a hell other than Earth in other forms of Buddhism. I wouldn't worry about it as Buddhism is pretty stupid to begin with. Hinduism FTW.
