Between 1941 and 1945, the years of cataclysm for European Jewry, the sixth Lubavitcher Rebbe published a remarkable monthly journal entitled Hakeriah Vehakedusha-"Reading and Holiness." A collection of discourses from this journal is published here for the first time in English translation. Many of the discourses have as their central theme the concepts of self-sacrifice for G-d and the Jewish people, repentance and strengthening the observance of Torah and mitzvot. The Rebbe often speaks of the lessons to be learned from the earth-shattering events of that time and their connection to the coming of Mashiach. They were written for a broad audience and are accessible even to those who have never studied Chasidic philosophy. The two volumes include explanatory footnotes, a glossary of Hebrew terms, a general index and, in the second volume, an index of quotations and references for Volumes 1 and 2.
