One who contributes from his wealth for the purpose of writing or publishing a sefer of a Tzaddik –
Behold, at any given time, and in any corner of the world, that a person studies from this sefer, the Tzaddik [on high] evokes merit on behalf of the donor through whom the sefer was disseminated.
—The Rebbe, Igrot Kodesh, vol 2
Chasidic discourses by the fifth leader of Chabad-Lubavitch, Rabbi Shalom DovBer Schneersohn, delivered during the years 5646-5650 (1886-1890).
The discourses of Rabbi Shalom DovBer are distinctive in their systematic approach, lengthy explanations and broadness of scope. It is because of this that he was given the appellation "The Maimonides of Chasidism".
