Likkutei Sichos
Likkutei Sichos, literally, ``Collected Talks'' (Hebrew: ליקוטי שיחות‎) contains both the scope and the core of the teachings or the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, and is the most authoritative source text for the Rebbe's unique, original, and often revolutionary explanation of Judaism.
