Shalom u'Vrachah!

I received your letter pleasantly, written on the day of the hilulah of our master, teacher, and Rebbe, my father-in-law, of blessed memory. You referenced Pardes HaTorah regarding the significance of a person's name—how for every individual it is said that the Holy One places in the parents' mouths the name necessary for that soul according to its source in Adam HaElyon from which it is hewn, and this name is inscribed above on the Throne of Glory (see Shaar HaGilgulim Introduction 23; also Emek HaMelech Shaar 1 end of ch. 4; Ohr HaChaim Hakadosh Devarim 29:19; Degel Machaneh Ephraim on Bereishit and others). How much more so regarding the name of a Nasi Yisrael whose soul is like a head and brain for the souls of our generation, as explained in Tanya ch. 2.

It is worth adding a hint based on what you wrote: Yosef has a gematria equal to six times Havayah (see Likutei Torah by Arizal Parashat Vayeshev and elsewhere), and he was the sixth generation from Rabbeinu HaZaken, founder of Chabad Chassidus. Yitzchak has a gematria equal to eight times Havayah (Pri Etz Chaim on Haggadah ch. 28), as he was the eighth generation from the Baal Shem Tov, founder of general Chassidus (see also Likutei Torah by Arizal at end of Parashat Vayeira regarding Yosef and Yitzchak and these gematrias).

As is known from our Sages' explanation on "Bereishit bara Elokim" (In the beginning G‑d created), that initially G‑d wished to create the world with attribute of judgment but saw it would not endure so He combined it with mercy—as it says "on the day Hashem Elokim made earth and heavens." This combination means miraculous conduct in this world through tzaddikim, alluded to in their very names: Yosef—"Yosef Hashem li ben acher" (May Hashem add for me another son), which Tzt"z explained as transforming 'another' into 'son.' Yitzchak—"Tzchok asah li Elokim" (Elokim made laughter for me), through refining and purifying the concealment associated with Elokim (which shields Havayah), our mouths will be filled with laughter in time to come (see Midrash HaNe'elam Bereishit 115a ff.), through avodah during exile.

One who contemplates the life story and actions of my father-in-law, our Rebbe in this world, will see that these two aspects—being one—are indeed both foundation and ultimate purpose of his holy work.

I am enclosing a copy of my letter regarding one of our customs which will surely interest you.

With honor and blessings for health.

Summary

The Rebbe teaches that deep spiritual meanings are embedded in names—especially those of tzaddikim. The names Yosef Yitzchak reflect both mercy and judgment united in leadership, mirroring essential qualities needed for guiding generations through challenge toward redemption.
