Okay, I will start.
I think we are here to learn lessons we need to, which didn't take or we didn't learn in previous lives. As in, themes for your life--like hero, builder, analyzer, controller, healer, humanitarian, etc,,,, And we return until we complete these. From there, who knows? We go onto to something further. I think many on this board are these themes. There are others, but I think I am done for now...........
