Nshei Chabad Newsletter / From the beginning of Av, we "diminish in simcha." The Rebbe translated "in" as "through," thus interpreting this dictum of our Sages as follows: From the beginning of Av we diminish [the unfavorable aspects of Av] through simcha - of course, simcha which is permissible at that time according to the Halochoh.
