Translated for the first time from the original Persian into English, these selected treatises from Aziz O-Din Nasafi's thirteenth-century work The Perfect Being provide a fascinating and rare, yet applicable, introduction to Sufism. The Perfect Being reads like a personal journal as well as a manual for those interested in Sufism. Its lucid exposition of the journey toward self-knowledge is both profound and eloquent, practical and transcendent. Presented here alongside a helpful introduction and explanatory notes to guide the reader, this book serves as a valuable introduction to classic Islamic texts.
