Based on a Naaleh.com shiur by Mr. Shira Smiles
The Gemara in Tannit tells us, “There were no yomim tovim (good occasions) in Israel more joyous than the 15th of Av and Yom Kippur.” The spiritual happiness of atonement on Yom Kippur was deeply felt but what was so significant about Tu B’av?
The Gemara lists several occurrences. On this day the tribes were permitted to intermarry, the ban against marrying into the tribe of Binyamin was lifted, the generation of the desert ceased dying, Hoshea ben Eleh removed the sentries blocking the roads to Jerusalem, the massacred Jews of Beitar were buried, and the wood for the altar was finally cut for the next year’s sacrifices. In addition, the Mishna tells us that on this day the daughters of Jerusalem would go out in borrowed white clothing and dance in the fields and matches were made. But the Gemara alludes to something deeper. It tells us about the marriage bond between Hashem and the Jews. In the future, the tzadikim will form a circle in Gan Eden and dance and point to Hashem and say, “Zeh Hashem kivini lo (This is Hashem, we have put our faith in Him).” What does dancing signify and why did the women in particular celebrate? What is the significance of borrowed clothing? Why does the Gemara give six reasons for the holiday, wouldn’t one have been sufficient?
Tu B’av celebrates re-unification both among the Jewish people and with Hashem. When there is unity there is true joy. Disparity creates a terrible kitrug (accusation) in heaven. The beit hamikdash was destroyed because of dissension. On Tu B’av, the barriers between the tribes were lifted. When the generation of the desert stopped dying, Hashem’s anger dissipated and He renewed His relationship with us once again. We celebrate the completion of gathering the wood because there is no greater joy than completing a mitzva. Now that they could ascend to Jerusalem, they could once again bask in the close proximity of the Divine Presence. Tu B’av is about separation and re-unification, distance and return. The knowledge that Hashem is One, creates unity. In the past we sensed this oneness and in the future we will once again experience it. This is the meaning of the Gemara that the tzadikim will dance in a circle. A circle is equidistant from the center. In the future world there will be total unity. Each tzadik will be able to see from the vantage point of his friend. This too is why the daughters of Tzion went out in borrowed clothing. Borrowing clothes signifies friendship and harmony.
The common thread between Tu B’av and Yom Kippur is atonement. On Yom Kippur, the sin of the Golden Calf was forgiven while on Tu B’av the sin of the Spies was forgiven. This is why the women celebrate. They had no part in either sin. Tu B’av commemorates the burial of those massacred in Beitar. This teaches us that we must be grateful for the slightest good even in the midst of overwhelming tragedy. Likewise matches were made on Tu B’av. A marriage can only function if we recognize the smallest benefit we receive from our spouses. The Sages designated Tu B’av as a holiday in order to help us bear our exile. By being thankful for the smallest good we can overcome our suffering. Sometimes in life, it’s not about the one big answer, it’s about the little reasons. If we can be grateful for all the small chasadim (kindnesses), we can build a genuine relationship with Hashem.
The Gemara calls both Yom Kippur and Tu B’av Yamim Tovim. Tov connotes something lasting. Yom tov is an elevated day whose qualities transcend time. It represents eternity even amidst adversity. Yom Kippur is about forgiveness of sin. Likewise Tu’ Bav, which follows close on the heels of Tisha B’av, signifies rebirth from destruction.
