I'm a great believer in the hereafter, in karma, in reincarnation. It does make sense. I believe that God is not just a law-giver, but a creative artist. The greatest of all. And what characterises artists is that they want to redo their work. Maybe it didn't come off perfectly, so they want to see it done again, and improved. Reincarnation is a way for God to improve his earlier works.
