Tisha B’Av, the Fast of the Ninth of Av is a day of mourning to commemorate the many tragedies that have befallen the Jewish people, many of which coincidentally have occurred on the ninth of Av.
Tisha B’Av primarily commemorates the destruction of the first and second Holy Temples which stood in the holy city of Jerusalem, both of which were destroyed on the ninth of Av (the first by the Babylonians in 586 B.C.E.; the second by the Romans in 70 C.E.). It is also appropriate to consider on this day the many other tragedies of the Jewish people, many of which occurred on this day, most notably the expulsion of the Jewish people from Spain in 1492.
Though we remember the tragedies and are saddened by them, it is a time of joy. One should not be overcome by the sadness, but remember that the Holy One, blessed be He hears the prayers from our broken hearts and provides us with many opportunities.
It once happened that some rabbis walked through the holy city of Jerusalem everyday, and when they came upon the Western Wall they would remember the Holy Temple and cry.
