"Rustom's Inrushes of the Heart is a welcome addition to the corpus of scholarly literature regarding 'Ayn al-Quat, a list of which he thoughtfully provided in the back matter of this book . The range Rustom tries to cover is vast. It makes the book an excellent guide for someone new to 'Ayn al-Quat, giving the reader a spectacular overview and a holistic and comprehensive outline of the philosophy of the Sufi of Hamadan." -- Islamic Studies "I am delighted that Mohammed Rustom has written this much-needed book which finally does justice to the teachings of 'Ayn al-Quat, one of the most original and inspiring authors during a period that bore witness to a great flowering of Sufi teachings wedded to philosophical and theological acumen." -- William C. Chittick, Distinguished Professor, Stony Brook University "In the fields of Islamic philosophy, mysticism, and theology, there is nothing remotely like this book, in any language, and it should therefore remain a standard reference and teaching resource for decades to come." -- James Winston Morris, Professor Emeritus, Boston College "Bringing to light the full spectrum of 'Ayn al-Quat's bold and creative writings for the first time in modern scholarship, Inrushes of the Heart shows with blinding clarity why 'Ayn al-Quat is to be seen as one of the most luminous stars in the night sky of Islamic spirituality and intellectuality." -- Omid Safi, Professor of Islamic Studies, Duke University "The lucid translations and painstaking historical research on display in Inrushes of the Heart can serve as a model for scholars of religion and philosophy in general, and Islamic thought in particular.

This definitive book on one of pre-modern Islam's most significant thinkers will be an indispensable resource for students and researchers for decades to come." -- Cyrus Ali Zargar, Al-Ghazali Distinguished Professor of Islamic Studies, University of Central Florida "'Ayn al-Quat's scintillating spiritual prose is brought to life in this brilliant anthology by Mohammed Rustom. Rustom's impeccable historical and philological scholarship creates a conductor for 'Ayn al-Quat's lightning-like flashes of insight on the nature of reality, humanity, intellect, ethics, and revelation. Inrushes of the Heart is a veritable defibrillator, shocking our spiritual hearts back to life." -- Oludamini Ogunnaike, University of Virginia.
