By Rabbi M. M. Shneersohn (Tzemach Tzedek); Translated by Eliyahu Touger
Derech Mitzvotecha dives into reasons behind mitzvot such as tzitzit, tefillin, prayer, belief in G-d, loving a fellow Jew, starting a family and many others. Five generations later, the author's grandson and successor, the Rebbe, Rabbi Menachem M. Schneerson, has often advised those seeking to begin study of Chasidic philosophy to study this fundamental work.
