Editing The Mitteler Rebbe (section)

==== Lubavitch ====
The journey concluded with the Mitteler Rebbe choosing the town of Lubavitch as his residence, arriving there with thousands of chassidim on the 18th of Elul 5573. Upon arrival, the Mitteler Rebbe told the chassidim that the Alter Rebbe had studied in Lubavitch during his youth under Rabbi Yissachar Ber of Lubavitch. He added that the Alter Rebbe had appeared to him and requested that he establish his seat in Lubavitch.

Prince Tchekhovskiy, who ruled over the town, commanded his workers to cut trees from his forests to build homes for the Rebbe and the chassidim.

From Lubavitch, the Rebbe's teachings - Toras Chassidus Chabad - began spreading throughout White Russia and Lithuania, and the number of visitors to Lubavitch steadily increased.

A year after establishing his residence in Lubavitch, many of the elder chassidim who had been close to his father, the Alter Rebbe, began coming to hear Chassidus from him. All were filled with amazement at the leadership of the new Rebbe and the chassidic discourses (maamarim) which he delivered abundantly, as was his way. Sometimes he would deliver Chassidus multiple times during the same Shabbos, each time for several hours. On one Shavuos, the Rebbe said Chassidus 11 times in one day! Regarding this, his uncle Rabbi Yehuda Leib, the Alter Rebbe's brother, remarked: "Lav kol mocha sovil da" (not every mind can bear this).

During his nesius (leadership), the number of chassidim multiplied two and threefold compared to their numbers during the Alter Rebbe's time. The elder chassidim related that in his first year of leadership alone, fifteen thousand new chassidim joined in White Russia alone, and in the second year, 5575, the entire Chernigov region became a center of Lubavitch Chassidus.
