Asher Tzvi ben Dovid of Koretz and Ostrog. Ma’ayan HaChachmah [Chassidic discourses]

The author was one of the outstanding disciples of the Maggid of Mehzritch and highly respected within Chassidic circles. Abraham Joshua Heschel, Rabbi of Apt, stated that all of R. Asher Tzvi’s writings were directly inspired by the Divine Spirit. See Y. Raphael, Encyclopedia LeChassiduth, p. 394-95; Y. Alfasi, Traklinei Chassiduth, p. 75 no. 24. The previous owner of this copy R. Yisrael Shalom Yoseph of Bohush (1863-1923) author of Pe’er Yisrael, was the son of R. Yitzchak of Bohush, grandson of R. Yisrael of Ruzhin. Of interest, one of his Chassidim, a shochet, signs his name on the title-page “Elazar ben Brachah” (specifically using his mother’s name) in order to obtain a blessing from the Rebbe.
