Kalman Nachum Fisher was a communal leader involved in Jewish public affairs in the camp at Shaabagyn, as indicated by the correspondence he received from the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson.
The Rebbe addressed Kalman Nachum Fisher with warmth and appreciation, expressing satisfaction with his dedication to communal matters among the Jewish residents of the camp. The Rebbe acknowledged Fisher's efforts to involve others in these activities and encouraged him to continue spreading blessings and good will to all participants, both current and future. The tone of the letter is encouraging and supportive, emphasizing the importance of communal involvement and spiritual growth.
In his letter, the Rebbe sent Fisher a copy of the Sefer HaSichos of the previous Rebbe, Rebbe Rayatz (Rabbi Yosef Yitzchak Schneersohn), and advised him to share the teachings with the public at appropriate times, such as during Shalosh Seudos (the third Shabbos meal) or on special days. The Rebbe highlighted that the teachings are suitable for all, from great scholars to the simplest individuals, reflecting the Chassidic ideal that Torah truth must reach everyone, as explained in Tanya chapter 23.
The Rebbe also inquired about the public Torah study sessions held in the synagogue, expressing interest in whether they followed the directive of the previous Rebbe to recite Tehillim daily after prayers, as well as the regular study of Chumash with Rashi and Tanya according to the daily schedule. The Rebbe concluded with blessings for both material and spiritual success, and anticipation of good news.
