This discourse presents a modern-day perspective on the Biblical command to offer animal sacrifices. Rabbi Schneur Zalman teaches that each of us possesses certain character traits that can be seen as "animalistic," or materialistic, in nature, which can lead a person toward material indulgence. Our mission, then, is to "sacrifice" and transform the animal within, through meditating upon the greatness of G-d. This ultimately alters the very composition of one's materialistic traits, so that they too may gain an appreciation of the spiritual, and develop a love for G-d. This volume, a member of the widely popular Chasidic Heritage Series, is complete with extensive notes, footnotes, and fluid English translation.
