Jewish Valentine's Day? Not exactly.
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.
The energy of the mini holiday of Tu B'av is the energy of love, and celebrates the possibility of two hearts, minds and souls joining forces to make a holy life together.
