Mehr is an ancient Persian deity associated with the sun, light, and friendship. In Zoroastrianism, he represents truth, loyalty, and the bonds of love and trust among people. Mehr is often depicted as a youthful figure, symbolizing warmth and the nurturing aspects of the sun. In addition to his role in mythology, Mehr is also linked to the concept of justice and the protection of oaths. His influence extends to various cultural practices, including the celebration of Mehrgan, a festival that honors the harvest and the changing seasons, reflecting gratitude for the earth's abundance.
