In connection with Lag B’Omer, the Rebbe frequently called for the singing of the Chassidic melody set to the words of the verse (associated with Rashbi), Hinei mah tov u’mah na’im, sheves achim gam yachad, “Behold, how good and how pleasant it is, when brothers dwell together!”
As we advance further into Lag B’Omer – the time associated with the sefirah of hod shebehod – more and more is accomplished. In addition, the very conclusion of the day (after the Minchah prayers, including even belated Minchah prayers…) belongs to the very lowest of levels within hod shebehod; it is the conclusion (sof ma’aseh, the actual implementation) in which literally radiates the very highest of levels (machshavah techilah, the origin conception in thought). (Ibid., p. 177)
