Letter from Rebbe Menachem Mendel Schneersohn - the Lubavitcher Rebbe, with his signature. Brooklyn NY, 26th Kislev 1971.
Typewritten on the official stationery of the rebbe, with his signature, and the addition of several words in his handwriting.
Public-private letter addressed to R. Chaim Nachman Kowalsky (1892-1978), in honor of Chag HaGeulah of the Baal HaTanya - Yat (19th) Kislev, and in honor of Chanukah.
In his letter, the rebbe explains the double virtue of Yat Kislev that year falling on Tuesday, the day on which G-d declared twice "it was good", and blesses that this should inspire each and every person to redouble their efforts and activities, in the study and teaching of Torah, and performance of acts of kindness, imbued with a love both for G-d and fellow Jews.
At the end of the letter, the rebbe added his handwritten blessings for "success, longevity and good tidings".
References and sources of the ideas mentioned in the letter were printed at the foot of the letter (most of the sources were printed on the second leaf of the letter, which is not present).
