This discourse revolutionizes the age-old notion of Monotheism, i.e., that there is no other god besides him.

While much has been written about the rich history of the Rabbeim of Lubavitch - their incredible accomplishments, mesiras nefesh, love for every Jew, and teachings - the life of the Rabbe Maharash has largely remained shrouded in mystery.
Drawing his material from documents as well as from unpublished sources, memoirs of participants and family members, such as his father, Rabbi Shalom DovBer of Lubavitch; his grandmother, Rebbetzin Rivkah, and from elder Chasidim whose company he kept in his youth, Rabbi Yosef Yitzchak wrote prolifically, chronicling for posterity the rich tradition of his forebears.
