As per your request, I mentioned you at the gravesite of my
revered father-in-law, the Rebbe, ‫הכ״מ‬. A tzaddik grants blessing
and G-d fulfills those blessings in a full sense.
Signing with blessing for you and your entire household,
Menachem Schneerson
[With regard to] what you wrote concerning the Ofanim and
the Seraphim and their source in the realm of Tohu as mentioned
in the letter cited above, see the maamar entitled Mi Chamocha
from Acharon Shet Pesach, 5688. There the concept is explained
No. 701
This letter was sent to R. Gershon Chein, one of the
members of the Lubavitch community in Eretz Yisraet.

Greetings and blessings,
In response to your letter of Wednesday of Parshas
Vees'chanan. There was no need for you to apologize for what you
wrote me, because there wasn't even a thought of an objection
[on my part]. I am always happy to hear about what is happening
with the members of the chassidic fellowship. It is just that
positive information causes gratification and happiness. But if the
opposite [occurs], Heaven forbid, the interchange of letters is
reinforcing and lessens the feelings of aloneness and depression.
As is well known, in several texts it is explained that even if one
cannot help a person in a physical way, the good thoughts and
positive wishes of one Jew to his colleague are of substance. As is
well known, there is a positive influence drawn down into the
world through speaking about a friend's positive qualities and
what he needs in a revealed manner. This has an effect, either
immediately or at a later time, in easing [the other person's]
situation. (See the explanation in the analogy given by R. Hillel
of Paritch quoted in HaTamim, Vol. 2, and printed in Kovetz
