I've heard that Japanese thought about life is based on circle. In Japanese, the circle is called "rinne". Rinne is one of the word of Buddhism. It means that we'll be born to this world again and again by changing the shape, in other words, life is forever. On th other hand, I've also heard from my friend who is a Christian that afterlife is forever and we are judged whitch is proper to us heaven or hell at first and we shoud obey the judgement forever.
Since there are no proofs, it is hard to believe it completely, but I think both of them possible because no one (at least who is living) knows about the afterlife. By the way, I think it is interesting that there are many method about circle and life.
