1. Establishment of Tomchei Temimim Yeshiva
The 15th day of Elul holds special significance as the day when the yeshiva of Tomchei Temimim—the Lubavitch Yeshiva—was established. This took place in the year Tarnaz—תרנ"ז, corresponding to 5657, or 1897 on the secular calendar, specifically September 12th. Prior to this, there was higher Torah learning, but it was not organized in a formal way. The Rebbe Rashab, Reb Shalom Dovber, set up the yeshiva to provide structured study that included both Chasidus and Nigleh—the revealed part of Torah.2. Unique Approach of Tomchei Temimim
The innovation of the yeshiva was its dual curriculum: students would learn both the inner teachings of Torah (Chasidus) and traditional Talmudic studies (Nigleh). This approach was designed to produce well-rounded individuals who excelled in both areas. The founding of the yeshiva marked a new era in organized Torah learning within Chabad and had a lasting impact on Jewish education.3. Significance of Elul 15–18 for Hasidus
Because the yeshiva was founded on the 15th of Elul, these days—from the 15th through the 18th—are considered especially appropriate for increasing one’s study of Chasidus. The Rebbe emphasized that this is based on teachings from the Baal Shem Tov, the Alter Rebbe, the Rebbe Rashab, and especially from his father-in-law, the previous Rebbe. During these days, one should make an extra effort to add to their learning, particularly in areas connected to Chasidic thought.4. Practical Applications: Classes and Personal Growth
In addition to maintaining established classes, there is encouragement to set up new classes during this period. The Rebbe specifically urged people to create new opportunities for learning and growth. There is also an emphasis on increasing one’s devotion in prayer (davening) and service of Hashem, as one of the goals of Tomchei Temimim is to cultivate students who are serious and devout in their spiritual service.5. Expanding Light Through Action and Community
The focus is not only on personal growth but also on communal impact. The Rebbe encouraged increased acts of charity (tzedakah)—both in a practical sense and spiritually by becoming luminaries who illuminate others with Torah values. Organizing large Chasidic gatherings (farbrengens) wherever there is a branch of Tomchei Temimim is also encouraged, as well as opening new branches where appropriate.6. Utilizing Significant Days for Spiritual Advancement
The Rebbe would often use significant dates in Chabad history as opportunities to inspire greater commitment to learning, prayer, and spreading Chasidic teachings. The founding date of Tomchei Temimim serves as a catalyst for renewed energy in these areas, aiming to bring the light of Chasidus as far as possible within every community. Thus, Elul 15 stands out as a day with special meaning for those connected to Chabad and its educational mission.
