B"H, Eve of Rosh Chodesh Kislev, 5717. Brooklyn.
Shalom u'Vrachah!
Surely you received my letter in response to your previous letter, and it is surprising that since then there has been no news from you. Surely this is a sign that you are increasing and elevating yourself in your matters—meaning in the study of Nigleh of Torah and Chassidus, and in the service of prayer, which is what truly establishes a person spiritually and thereby also physically. As it is written: Tamim tiheyeh im Hashem Elokecha ("You shall be wholehearted with the L‑rd your G‑d"), wholehearted in all 248 limbs and 365 sinews spiritually (see Likkutei Torah on the discourse Ki HaMitzvah HaZos), and wholehearted in all 248 limbs and 365 sinews physically—for even the Jewish body is holy.
The three panim were received at their proper time.
With blessing for good news in all the above matters as well as regarding your influence on your friends, may they be protected by G‑d, in all these areas.
Summary
The Rebbe encourages ongoing communication and growth in both revealed Torah and Chassidus. He stresses the importance of wholeness—spiritually and physically—and acknowledges efforts to positively influence others.
