The Gates of Repentance (Sha'arei Teshuvah), by Rabbeinu Yonah of Geronah (d. 1263), is one of the most important books of Jewish literature. Now available in a modern English translation, this volume probes the profound idea of teshuvah, often translated as "e;repentance"e; but in reality far more complex and subtle than the simple meaning of "e;regret for sin"e; or "e;contrition."e; Rabbi Feldman furnishes the reader with an eminently readable translation and provides notes directly on-site when difficulties arise in the text. He gives a general introduction as well as short introductions to each gate, followed by a synopsis of each gate for review and overview. Unique to this work are the scholarly notes Rabbi Feldman provides, which enable the reader to follow themes throughout the work, get a better understanding of other sages' insights, and develop to a higher level the ideas discussed in The Gates of Repentance.
