"This book is well written, tightly argued, and philosophically informed. It deals with an important issue that no one else has discussed in this detail. It is significant for Maimonides' scholarship and for philosophy of religion in general because it deals with a timeless question: the significance of prayer. Highly original and breaking new ground in its field, Worship of the Heart will be part of the standard literature on Maimonides." — Kenneth Seeskin, Northwestern University"This is an excellent and exceptionally exciting study. Benor's wide learning, his intelligence and intellectual acuity, as well as his willingness to tackle large, important, and difficult questions, are manifest on every page." — Lawrence Kaplan, McGill University
