The 15th of Av is undoubtedly a most mysterious day. A search of the Shulchan Aruch (Code of Jewish Law) reveals no observances or customs for this date, except for the instruction that the tachanun (confession of sins) and similar portions should be omitted from the daily prayers (as is the case with all festive dates), and that one should increase one’s study of Torah, since the nights are begining 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 the Talmud considers this 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 also ours to seek and explore.
