Rabbi Yisrael Zev Mintzberg was an educator associated with the Midrash Shmuel yeshivah, noted for his involvement in organizing and promoting the study of Chassidus within the institution.
The Lubavitcher Rebbe corresponded with Rabbi Mintzberg regarding the establishment of a fixed schedule for the study of Chassidus at the Midrash Shmuel yeshivah. In his letter dated 2 Shevat, 5712, the Rebbe expresses appreciation for this initiative, emphasizing the importance of consistent and proper study of Chassidic teachings. The Rebbe draws an analogy from halachah, likening the spread of the "secrets of Torah"—referred to as "oil"—to the way oil permeates its surroundings. He encourages even the smallest effort in spiritual growth, assuring that such beginnings will eventually lead to a broader and deeper impact on the soul, referencing the teaching that opening "the eye of a needle" leads to G-d opening "an opening as wide as a hall."
The Rebbe also enclosed suggestions for conduct in connection with the upcoming yahrzeit of Yud Shevat, underscoring their relevance and importance for all those involved with the beis midrash and yeshivah. His tone is warm and supportive, offering both practical guidance and spiritual encouragement.
