This book is devoted to Rabbi Joseph B. Soloveitchik’s discussions on the practice of prayer. Prayer is analyzed across a broad and complex spectrum in Soloveitchik’s work, and his writings describing and analyzing the experience of prayer afford a profound insight into its diversity, ranging from existential crisis to communion with God.Through a careful reading of R. Soloveitchik’s texts dealing with this topic, the book follows the consciousness of prayer across its various stages until maturity, starting with an analysis of Worship of the Heart, through to Reflections on the Amidah and other writings.
