Simcha Bunim of Peshischa. Kol Simchah [on Torah and Talmudic novellae]

Rabbi Simcha Bunim of Peshischa (1765–1827) was a seminal figure in the development of the Chassidic movement - in Poland especially. In his youth a student in traditional Academies in Mattersdorf and Nikolsburg, he was introduced by his father-in-law to an entirely different world - that of Chassiduth - and soon became a follower of the Kozhnitzer Maggid and the Chozeh of Lublin. Following the death of the Yid Hakodosh (R. Yaakov Yitzchak Rabinowicz) most of the latter’s chassidim subsequently looked toward R. Simcha Bunim as their Rebbe. The final leaf of this work contains a record of the celebrated cryptic letter by R. Simcha Bunim concerning the secret of Rosh Hashanah that was addressed to his disciples. These included the Kotzker Rebbe, the Chidushei Harim, the Mei HaShiloach, Mordechai Yosef Leiner of Izhbitz and many others of similar, great standing.
