Although a (fairly) atheistic person, I find the ancient mythology kinda interesting. The thought, that there is an underworld - which is parted into three.
The part, where to "good" people get rewarded, the part, where the "bad" people are punished - and the Fields of Asphodel, where the mostmajority is just standing around, the ones that never really made an impact, may it be in the wrong or right direction, the ones who just lived, who just "exist" there, in eternal mediocrity.
I like the moral that comes from this explanation of the afterlife.
