The book under review is a monograph on one of the most outstanding figures in the tradition of Islamic mysticism. Ruzbihan Baqli (1128–1209) is celebrated for numerous works he wrote in both Persian and Arabic, treating a range of subjects, from Qurءanic exegesis to prophetic traditions, Islamic law, theology, jurisprudence, language and grammar, Sufism, and biography. Ruzbihan is most renowned, however, for his extensive mystical writings, especially his עAbhar al-עashiqin (The Jasmine of Lovers), in which he meticulously outlines theories of mystical love, and his Sharh-i Shathiyyat, (Commentary on Ecstatic Saying), in which he offers a commentary on the ecstatic locutions of mystics, particularly Husayn Mansur Hallaj (executed 922). Ruzbihan belongs to the group of malāmatī (self-blame) mystics who, as described in this book, maintained “perfect obedience to the law in private and outrageous behavior designed to incur censure in public” (p. 10).
