The 15th of Av is undoubtedly the most mysterious day of the
Jewish calendar. A search of the Shulchan Aruch ("Code of Jewish Law") reveals no observances or customs for this date, except for the instruction that the tachnun (confession of sins) and similar portions should be omitted from the daily prayers--as is the case with all festive dates--and that beginning on the 15th of Av, one should increase one’s study of Torah, since at this time of the year the nights begin to grow longer and "the night was created for study." And the Talmud tells us that many years ago the "daughters of Jerusalem would go dance in the vineyards" on the 15th of Av, and "whoever
did not have a wife would go there" to find himself a bride.
And this is the day which the Talmud considers the greatest
festival of the year, with Yom Kippur(!) a close second!
Indeed, the 15th of Av cannot but be a mystery. As the "full
moon" of the tragic month of Av, it is the festival of the Future Redemption, and thus a day whose essence, by definition, is unknowable to our unredeemed selves.
Yet also the unknowable is ours to seek and explore, as we shall in two essays, based on the Lubavitcher Rebbe's writings and talks, presented here. The Day of the Breaking of the Ax approaches the mystery of Av 15 by examining a number of events which occurred
