The Lubavitcher Rebbe's colossal achievements in the service of world Jewry are well known. From his office in 770 Eastern Parkway, he initiated some of the most successful and innovative programming that the Jewish world has ever seen. What is not so well known is his scholarly prowess and his impressive mastery of the entire range of Torah disciplines. In this book, scholar Yosef Bronstein explores the philosophy and genius of Rabbi Menachem Mendel Schneerson, zt"l. Engaging the Essence addresses abstract philosophical issues, such as the nature of the material world and free will, as well as pressing contemporary issues, such as the Rebbe's approach to the State of Israel and the role of women in our generation. It also investigates the Rebbe's exceptional perspective on and push for "the true and complete redemption."
