I suppose it`s good we can`t remember our previous lives during our normal waking hours. It could get pretty complex out there. All those people. All those conflicts. All that karma bouncing all over the place. I mean, just imagine how many people you meet throughout a typical day. Try this: count. Count the number of people who cross your path for one day. Now imagine you know every single one of them and have a vast — multi-life — history with every single one. Yeah, awareness of one life at a time is probably best. At least while you are conscious anyway.
