In the unspeakable tortures of the Warsaw Ghetto, a bright light shone: the guidance and holiness of the Piaseczna Rebbe, the spiritual leader and spiritual father to thousands of followers until he was killed al kiddush Hashem. His saintly insight is preserved and presented in this beautiful volume, the work of a team of Torah scholars, who have rendered it into English thus adding another jewel to the crown of the Feldheim Torah Classics Library. In this wondrous work, the Rebbe explores the most effective approaches to achieve greatness in Torah learning and spiritual growth. His words are a salve and a salvation for every reader; his messages are timeless and penetrating. Also included in this volume are Sheloshah Ma'amarim, which discusses Kabbalistic concepts and was highlighted for its importance by the rebbe himself. This is the first work in an exalted project to publish all the works of the Piaseczna Rebbe in English translation to make them available to the greater public.
