Examining the role of the god of Mehr in the religious text of Mehr Yasht Avesta

The cult of Sun Worshiping has long been practiced in ancient Iran. But after the prosperity of Zoroastrianism by Zarathustra, Mehr, who was considered the god of Mehr and the sun, became the god of Mehr and descended from the rank of god, and in Avesta he was given a part called Mehr Yasht. The seal is not the same as the sun, but later the two were combined and considered one. In Avesta, the god of love is introduced as the angel of light and enlightenment, as well as war, and has the high qualities of power and heroism. In this research, which has been done as a library, we examine the role of god of Mehr socially and its function based on Mehr Yasht texts.
