Rumi and the Persian world

پارسی گو گرچه تازی خوشتر است — عشق را خود صد زبان دیگر است

Say all in Persian even if Arabic is better – Love will find its way through all languages on its own.

These cultural, historical and linguistic ties between Rumi and the Iranian world have made Rumi an iconic Persian poet, and some of the most important Rumi scholars including Foruzanfar, Naini, Sabzewari, etc., have come from modern Iran. Rumi"s poetry is displayed on the walls of many cities across the Persian-speaking world, sung in Persian music, and read in school books.
