Thanks yytz, appreciate the insight. It sounds to me like the concept is completely “di’rabbanan”, is that right?
it seems like we don’t have a lot to go on,(aside from some stories) we know that the reincarnation that hinduism and buddism teaches is nonsense, what makes anyone think that our neshamos really become something else if it isn’t mentioned anywhere in the torah?
In terms of your practical consequence, should’t you live a good life because you’re a mensch and know right from wrong?(and not because you fear coming back into a tough life?)
