Isaiah Asher Zelig Margaliot is identified in the correspondence as a Torah scholar involved in the publication and dissemination of works on the mystical teachings of the Torah, particularly those related to the Zohar and the teachings of Rabbi Shimon bar Yochai. He is associated with the authorship or distribution of the sefer Kocho d’Rashbi and other works on the inner dimensions of Torah.
The Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, wrote to Isaiah Asher Zelig Margaliot in appreciation for receiving the sefer Kocho d’Rashbi. The Rebbe expresses gratitude for the gift and requests that thanks be conveyed to the author. He also expresses interest in receiving additional works by the author for the Chabad library, suggesting the possibility of exchanging them for publications from Kehot, the Chabad publishing house.
The Rebbe commends the author for publishing a work that deals with the hidden aspects of Torah and the Zohar, emphasizing the redemptive power of these teachings: "with it Israel will be redeemed from exile with mercy soon." The tone is one of encouragement and support for the dissemination of mystical Torah study.
In his letter, the Rebbe notes with some surprise that although the author draws extensively from the teachings of the Baal Shem Tov and his disciples, he does not cite from the teachings of Chabad Chassidus, even when discussing topics addressed in Chabad sources. The Rebbe reflects on historical hesitations in certain circles regarding the study of Chabad teachings, comparing it to earlier reservations about the public study of the Zohar and the Baal Shem Tov's teachings. He argues that, over time, the benefits and necessity of these teachings have become clear, especially regarding the understanding of the Zohar and the fulfillment of the mission to "spread the wellsprings outward," which is associated with the coming of Moshiach.
The Rebbe encourages the study and integration of Chabad Chassidus, citing various sources in Chabad literature where the teachings of Rabbi Shimon bar Yochai are discussed. He emphasizes that engaging with these teachings enhances both faith and intellectual understanding of G-dliness, and that neglecting this area of Torah study is a significant missed opportunity for spiritual growth and fulfillment of one's potential in Torah study.
