If you look at history, Persian culture/civilization has to be one of the most advanced and classic civilizations. Compared to persians, Indians were nothing. Even if you look at middle ages, Mughals and others brought persian muslim culture in full force to the subcontinent, that completely changed the indian muslim identity in the subcontinent and gave us things like Taj Mahal or the Mughal Cuisine and the Urdu Language. Indian hindus fealt jealous all this while, because they could not even achieve 1/10 of what persian civilization had achieved. Even to this day, I think they envy the persians
