What lessons are being taught to human beings based on the myth of Demeter and Persephone?

Answer 1

Boy, you really don't want to do your homework, do you?

Pick out the themes of the myth. Like, what does Demeter feel when Persephone is taken away? Why would the lord of Death snatch away a symbol of so much life and fertility? What does Demeter feel when she comes back?

I'll give you a hint: cycles.

Answer 2

It explains the reason for the seasons! It's not a "lesson".
