Sha'arei HaYichud V'HaEmuna, commentary on the Tanya [on Sha'ar HaYichud V'HaEmuna], by Rabbi Aharon HaLevi "The one singular disciple of our great rabbi… Rabbi Shnuer Zalman [from Liadi] who was his student for thirty years and did not move from him until he revealed all the secrets of his wisdom…". Shklow, [1820]. First edition.
Rebbe Aharon HaLevi Horowitz of Strashelye (1766-1829, Encyclopedia L'Chassidut Vol. 1, pp. 147-151), a prominent disciple of the author of the Tanya. After the death of his rabbi in 1813, some of the Chassidim of the Admor HaZaken ordained Rabbi Aharon as his successor. Consequently, Rabbi Aharon established his own court and this instigated a fierce dispute between him and Rebbe Dov Ber ("The Middle Rebbe"), son and successor of the Ba'al HaTanya. The two also disagreed on the exegesis of the Tanya and on other issues of service of G-d. Nonetheless, his compositions and melodies were accepted by Chabad Chassidism. His many writings on Chassidism and Kabbalah were printed and are counted among basic Chassidic literature. Besides the first editions, his books were not reprinted for many years and are therefore rare.
