Shavuot-Spiritual Tools-The Rebbe RaShaB on Torah Study

Rav Shalom Dov Ber (ben Shmuel) Schneerson, the Rebbe RaShaB, was the fifth Lubavitcher Rebbe (1860-1920).  His Kuntres Etz HaChayim, employs far more technical wording than many other Chassidic sources. There are extensive quotes from the Zohar, the Etz HaChayim, and other Kabbalistic texts, as well as passages from the Talmud and the Midrash.
