B"H, 21 Sivan, may Hashem guard and protect.

Haraha"g veHaraha"ch vavac"h iy"a nu"m etc. Shneor Zalman Gerlik

Shalom u'Vrachah!

With much thanks I hereby acknowledge receipt of your letter from the 9th of Sivan, which informs in detail about the situation there.

Your news regarding the public Torah classes in general, and especially the organization of Chassidus study sessions and the detailed study of the holy writings of my father-in-law, the Rebbe hk"m our Nasi, was a great pleasure to me. Certainly you will strengthen and intensify these efforts more and more, and may Hashem be with you in this.

Surely you will inform which tractate is being studied; also make a public siyum as appropriate to strengthen the matter and increase the number of participants, etc.

It is surprising that you do not mention anything about Tanya study. Surely there are efforts to include in these studies even those who for now are not yet from Anash. It is well known how much my father-in-law, the Rebbe hk"m, was passionate about this.

Regarding speaking during prayer: it is proper to affix to the wall of the Beis Midrash Igros Kodesh section 24 and a copy of the great notice from my father-in-law regarding listening to Torah reading. Surely it exists among Anash in Tel Aviv or Jerusalem (it was also copied in the first collection of my father-in-law's letters published by Reb Aharon Paris).

Concerning learning Mishnayos by heart: surely you are aware of my father-in-law's letters on this subject printed in his second collection of letters. As for why specifically Mishnayos by heart etc., I explained what seems correct to me in L'Yubavitch Collection IV.

Regarding the mehudar mikvaos in Kfar Chabad: please write in advance how they were constructed—whether from a spring or rainwater via hashakah or another method; how they are maintained when cleaning is needed; if there is any tradition regarding this beyond what was written to me by Haraha"g etc. Yisroel Landa.

On reaching seventy years for long good days and years—I wish him that he merit fulfillment of the verse 'They shall still bring forth fruit in old age; vigorous and fresh they will be' (and thus be involved) 'to declare (and draw down) that G‑d is upright,' as explained in Likkutei Torah Re'eh s'deh Ki Tishma etc., HaYashar.

And since we mention our sages' words (Avos ch.5), it is known there is some question based on what is written by the Arizal (brought at end of Maamarim Ot Zayin): 'At fifty one attains elderhood; at sixty old age; at seventy fullness of old age.' The practical difference is whether one must be wise or outstanding for certain honors (see Kiddushin 32b; Yoreh Deah 244; Shaar HaMitzvos Arizal Parshas Kedoshim). For further discussion see Likkutei Torah end of explanation on 'I am black,' that fullness of old age refers to Atik Yomin—a place where abundant mercy and great kindness are found—may he find it soon.

Summary

The Rebbe encourages strengthening communal Torah study—especially Chassidus and Tanya—and emphasizes sharing details to inspire others. He addresses halachic questions about mikvaos and honors milestones with blessings for continued spiritual vitality.
