This is the only English translation of the esteemed Rav Kook's book on repentance and self-improvement. Rabbi Abraham Isaac HaKohen Kook's seminal work on repentance, Oros HaTeshuvah is recognised as a classic of Jewish thought but has, because of its difficult language and its theological depth, remained inaccessible to many. This book presents readers with the original Hebrew text of Oros HaTeshuvah with a new translation into English, as well as expert commentary in English from Rabbi Moshe Weinberger. Weinberger draws on his extensive knowledge of Jewish philosophical and inspirational literature to provide profound, moving, and fresh insights into the text, richly explicating the ideas in Oros HaTeshuvah in an accessible and clear but not superficial manner. Readers will come away with a firm grasp on the profound truth at the heart of Kook's classic work: that teshuvah -- repentance -- is not a somber process of self-deprivation but a joyful journey back to God and to the core of each individual. This volume covers chapters 14 to 17 of Oros HaTeshuvah and is the final volume in this series.
