In this collection, Fatemeh Keshavarz and Ahmet T. Karamustafa bring together leading researchers from comparative literature, history, literary criticism and religious studies to explore the major authors and genres of medieval Persian mystical literature. Breaking out of the all-inclusive literary history framework, the contributors write on topics that have energised their scholarship over time and address areas where the literary and the mystical have mingled and led to paradigmatic creations. How can you interpret the climactic conclusion to the framing narrative of The Speech of the Birds of 'Attar of Nishapur? How did 'Aziz Nasafi understand the concept of religion? What do Rumi's conversations with the Divine tell us about his teachings and his poetry? How do medieval Persian Sufi commentators add to our understanding the Qur'an? How can we utilise Sufi manuals, life stories and utterances? All of these explorations and more bring the depth and eloquence of Persian mystical literature to life in this volume.
