Here is the full daily lesson as delivered by The Rav, Rabbi Eliezer Berland shlit"a, on Tuesday night, the night of the 15th of Av, Parshas Eikev, after the Ma’ariv prayer:

“Today is the Fifteenth of Av—a day when you go out dancing all day and all night. You don’t stop dancing for even a second. It is like Yom Kippur. After Tisha B’Av, after Yom Kippur, we hear the Aseres HaDibros (the Ten Commandments). On the Fifteenth of Av it is possible to hear the Aseres HaDibros. Today [Moshe Rabbeinu went up to receive the Luchos] for forty days and forty nights; therefore there is no need to eat or drink—only to dance for twenty-four hours. And through this, the complete Geulah will come speedily in our days, Amen.”
