Twice a year we endure a night-day fast, on Tisha b’Av, when we commemorate the tragedies of Jewish life, and on Yom Kippur. On Yom Kippur the individual turns inward to evaluate her past and then looks forward, but Tisha b’Av is communal and seems to only look backward. The individual looks at Tisha b’Av and sees no relevance to his future. Quoting Cicero, Erica Brown writes: To remain ignorant of things that happened before you were born is to remain a child. There is an immaturity about individuals who have no grip on history and nations that have disregarded the past. Sadness and mourning are adult activities and as we end another year on the Jewish calendar, we are called to adulthood.
