Risālat al-anwār

Written for a friend in 602/1205 in Anatolia (probably Konya), this popular book describes the mystical ascension in terms of a constant progression through levels of existence and knowledge, leading to the ultimate degree of human perfection. It is framed as a journey to the Lord of Might (rabb al-ʿizza), who is beyond all qualification, and then a return to the world of creatures endowed with the knowledge of one's true reality.
