Wednesday Menachem Av 10 5703
Torah lessons: Chumash: Va'etchanan, Revi'i with Rashi.
Tehillim: 55-59.
Tanya: Upon his arrival (p. 395) ...the face..." (p. 397).

From what my grandfather related:

a) Originally the epistle Katonti1 ended with the words "restrained spirit etc." Later, our Great Rabbi (the Alter Rebbe) delivered the maamar "As water reflects the face etc." three times in Lyozna, following the interpretation of Rashi2 and not of Targum.3 After that he made an addition to the epistle Katonti as follows: And maybe, through all that, G‑d will give it into the heart of their brethren that "as water (reflects) the face" etc. With this he implanted fine character traits in the chassidim.

b) Had the Rebbe not inserted the three words b'midat emet leYaakov ("according to the attribute of Truth unto Yaakov")4, he would have attracted fifty thousand more chassidim. But the Rebbe demands the trait of truth.
