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
By Rabbi Dovber of Lubavich
With Rabbi Schneur Zalman of Liadi's discourses on the daily prayers as a foundation, his son, Rabbi DovBer of Lubavitch, the Mittler Rebbe, delves into the spiritual worlds affected by prayer and the nature of the soul in the act of prayer.
This work, first published by Rabbi DovBer, has benefited from a crisp typesetting and careful editing. Also known as Mehadurah Batrah, this book is the second version of the Mitteler Rebbe's discourses on the Alter Rebbe's Siddur.
