Sa'd ud Din Mahmud Shabistari (1288 - 1340)

Mahmūd Shabistarī (1288 – 1340) (Persian: محمود شبستری‎) is one of the most celebrated Persian Sufi poets of the 14th century. His most famous work is a mystic text called The Secret Rose Garden (Gulshan-i Rāz) written about 1311 in rhyming couplets (Mathnawi). This poem was written in response to seventeen queries concerning Sufi metaphysics posed to "the Sufi literati of Tabriz" by Rukh Al Din Amir Husayn Harawi (d. 1318). It was also the main reference used by François Bernier when explaining Sufism to his European friends (in: Lettre sur le Quietisme des Indes; 1688)
