many people come back from near death experiences with insight about the whole structure of the universe. one common theme they report is that we all chose the lives we’re living because these lives offered the best opportunity to learn and grow. they say we come back many times until we learn everything we need to.
so, if true, the downside is that you and I will probably be back. but, the upside is that we won’t keep coming back forever and that we can curtail the number of times we will return by being the best people we can and by learning as much as we can.
