The Kashf al-mahjúb - The oldest Persian treatise on Súfiism #603572

This translation of the most ancient and celebrated Persian treatise on Ṣúfiism will, I hope, be found useful not only by the small number of students familiar with the subject at first hand, but also by many readers who, without being Orientalists themselves, are interested in the general history of mysticism and may wish to compare or contrast the diverse yet similar manifestations of the mystical spirit in Christianity, Buddhism, and Islam. The origin of Ṣúfiism and its relation to these great religions cannot properly be considered here, and I dismiss such questions the more readily because I intend to deal with them on another occasion. It is now my duty to give some account of the author of the Kashf al-Maḥjúb, and to indicate the character of his work.
