Tefilla is at the heart of avodas Hashem, and we all strive to refine the way we daven. To this end, many have turned to Rav Chaim Volozhin's monumental sefer Nefesh HaChaim, where tefilla is one of the four main themes. For all its greatness, though, many have been unable to translate his works into practical actions. In this kuntrus, Rav Reuven Leuchter has endeavored to open up the Nefesh HaChaim to our generation. With deep insights, logical organization of the topics, and an ear to the modern ben-aliya, Rav Lauchter, a well-known mashgiach, has produced a work to accompany every ben-aliya as he ascends heavenward with his tefillos.
