I was chatting to this guy and was presented with the theory of the once born, meaning that some humans have not lived before and others have. He hinted that the once born often seemed a bit "childish", and never really "got" certain emotional dilemmas, and all together never really understod other people.
Do you belive in this? And if so, how about the part about the once born being "a bit primitive"? Or is it just a bit to convenient of an explanation?
