What happens on earth while Persephone is in the underworld?

While Persephone is in the underworld, her mother Demeter, the goddess of agriculture, mourns her absence and withdraws her blessings from the earth. This results in a period of barren land, where crops fail and winter prevails. When Persephone returns to the surface, Demeter rejoices, and spring arrives, restoring fertility and life to the earth. This cyclical myth symbolizes the changing seasons and the relationship between life and death.
