Mythical tales that highlight the duality of light and darkness often feature characters representing opposing forces. For instance, the struggle between good and evil in the Zoroastrian myth of Ahura Mazda and Angra Mainyu exemplifies this duality. Similarly, the Greek myth of Persephone illustrates the seasonal cycle through her relationship with Hades, embodying the balance of life and death. These narratives explore how both aspects are essential to existence, shaping moral lessons and personal development.
