Shalom u'Vrachah!

In response to your letter from the 26th of Iyar: as you requested, your eldest son... may he live and be well, will be mentioned at the holy resting place of my revered father-in-law, the Rebbe—of blessed memory—leader of Israel, for an improvement in his health. It is already known from our Sages that wine used for Kiddush and Havdalah increases a person's eyesight.

Regarding what you wrote about thoughts*, it is brought in holy books that one who has a book should return his thought, etc.—that by studying from a text directly, the letters shine and help to nullify unwanted thoughts. Even when a book is not available, since words of Torah are engraved in one's memory—especially from the inner dimension of Torah called Ilana DeChayei (the Tree of Life), where there are no difficulties etc., as it is written: "Ve'et ruach hatumah a'avir min ha'aretz" ("And I will remove the spirit of impurity from the land") (see Ra'ya Mehemna Parshas Naso as brought and explained in Igeres HaKodesh by our master the Alter Rebbe section 26)—all this pushes away darkness; these are thoughts that come from darkness. It is already known that thought always wanders (unlike speech, which has a time to be silent), and one pushes away an unwanted thought specifically with a holy thought.

As we approach Shavuos—may it come upon us for good—and according to our Sages' teaching that one must speak in the language of his teacher (that is, my revered father-in-law, the Rebbe), may it be His will that we merit immediately to receive the Torah with joy and inwardness.

P.S. Regarding what you wrote about Kehot publications: it seems it was already written that you should turn to those involved with this matter in Eretz HaKodesh—foremost among them Rabbi Avraham Pariz at 16 Bar Kochba Street, Petach Tikvah.

* Surely you also put on Tefillin of Rabbeinu Tam—mohin d'abba. And apparently it is time to check both sets—the Tefillin of Rashi and those of Rabbeinu Tam.

Summary

The Rebbe teaches practical ways to improve spiritual health: using Kiddush wine for physical benefit, combating negative thoughts through direct Torah study and memorization—especially inner Torah—and preparing for Shavuos with joy. He also emphasizes proper care in mitzvah observance like Tefillin.
