After twelve during the night between Tuesday of the week of Parshas Shlach, 14 Sivan, and Wednesday, 15 Sivan, I received the last of that night’s callers. The time set aside for this was always Sunday, Tuesday and Thursday, from 7:00 to 10:00 p.m., but it generally lasted for another hour or two, especially in the summer, when the earliest possible time for Maariv was 10:30. In the summer, Minchah would be held at 6:00 and Maariv at 11:00. (At other times, Minchah would be at 9:00 and Maariv would follow at nightfall.)
I had a regular minyan three times a day. After Shacharis people would read a daily allotment of Tehillim (as divided up in a monthly cycle). By reason of a directive that remained unexplained, I requested the members of the chassidic brotherhood everywhere to establish this custom — the daily reading being followed by the Mourner’s Kaddish — in all shuls. This proposal has been accepted by people in many places, thank G‑d; happy is their lot, both materially and spiritually. This request still stands. Tehillim is to be followed by a regular session in the study of Mishnayos; between Minchah and Maariv is the time for Aggadah; and Maariv is followed by a shiur in Gemara.
On this day there were very many callers. I had to begin at the appointed time, I finished at 11:30 p.m., and then it was time to daven Maariv. My labors left me exhausted. In addition, for me those were most distressful days, because on Sunday, Monday and Tuesday there had been verbal exchanges — via R. Aronovski, the Rav of Velizh, and the Rav of Sdeh Menuchah — with the elderly R. David Tevel Katznelenbogen, concerning a general meeting which the Leningrad Congregation had wanted to call.
