Russian government, to special sensitivity to the Chassidus and Kabbalah (spiritual dimensions of the Torah) to his genius in the revealed Torah. Scholarship Rosen was a noted Talmudic scholar and published a number of his works on the Talmud and Maimonides. His main work, a commentary on Maimonides, was published during his lifetime, as were five volumes of halakhic (Jewish law) responsa. The remainder of his surviving writings appeared in the United States and Israel many years after his death; all are titled Tzofnath Paneach (Decipherer of Secrets—a title given to the Biblical Joseph by Pharaoh). His manuscripts were smuggled out of Latvia in the form of micro photographs sent via mail to the Safern family in the Bronx at the outbreak of World War II by his successor, Yisrael Alter Safern-Fuchs (1911–1942), who remained in Latvia to complete this task, and his daughter Rachel Citron, who had come to Dvinsk from the Land of Israel to help preserve her father's manuscripts. Both were murdered in the Holocaust. A portion of these manuscripts was edited and published by Menachem Mendel Kasher. Seven manuscripts were published by Machon Tzofnas Paneah, headed by Mordechai Pinchas Teitz. Machon Hamaor in Jerusalem is now publishing the remaining manuscripts. Rosen's approach to Torah study is discussed in Shlomo Yosef Zevin's Ishim v'Shitot (Personalities and Approaches). Rosen's works include responsa and novellae on Torah and Talmud. They are regarded as difficult and inaccessible, as he employs the philosophical terminology of Maimonides' The Guide for the Perplexed even in non-philosophical analyses. Kasher, therefore, included Mefa'aneach Tzefunoth (Decipherer of Secrets), an explanatory commentary to facilitate understanding of Rosen's influential work.
