To me, I don't even think of life after death. To me, life after death and reincarnation are just slices of the pie. Life is a huge wheel and it goes around and around, and life after death is just a segment of that. It comes down to spiritual growth. I think that we keep coming back until we learn what we need to learn, until we get it right.
I think we've all lived hundreds, maybe thousands of times. That which you think becomes your world. It's only when we're alive and in this world that we have the chance to progress. From the state of the world today, we haven't made much progress.
