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
Path to Selflessness
by Rabbi Menachem M. Schneerson the Lubavitcher Rebbe
Beginning with the words Yehuda Atah , the discourse examines the blessing which Yaakov blessed his fourth son, Yehuda, as compared to the blessings he gave his first three sons, Reuven, Shimon and Levi. Yaakov`s sons embody distinctive forms of divine service, which correspond to distinct sections of the prayers of Shema and the Amidah. Using these distinctions, the discourse further derives lessons about the bond between the individual Jewish soul and G-d.
