...and to learn from the Mitteler Rebbe [second Chabad Rebbe, about 200 years ago], whose perfection of work in the teachings of Chassidus was expressed in the physicality of the body and the world (in time and place), “He [G-d] fills their years from day to day” [the Mitteler Rebbe passed away on his birthday] – that everyone should put a special effort into expressing one’s spirituality and “Chassidishkeit” in one’s physicality, that in one’s physical matters, and in one’s physical time and place, there will be felt the warmth and liveliness that come from one’s “Yiddishkeit” (Jewishness) and “Chassidishkeit” (Chassidic-ness), until in a way that there won’t be any separation between them at all, rather they will be one thing actually.
We should make Farbrengens (Chassidic celebrations) for the Holiday of Redemption of the Mitteler Rebbe on the 10th of Kislev (this year, Sunday, Nov. 30) in every place, and speak about and learn his teachings, and take on good resolutions in the above matters.
Including making big Farbrengens for the 19th of Kislev, the Holiday of Redemption of the Alter Rebbe [the first Chabad Rebbe] on the 19th of Kislev. We should make sure to hold these Farbrengens everywhere in all ends of the earth, even in a remote corner – in a way that every corner of the physical world where Jews are will be permeated with the Chassidic light and warmth of the 19th of Kislev, the “Rosh Hashanah of Chassidus”.
