Tisha b’Av is a day of communal grief-- we fast, lament and hold the memory of the greatest catastrophes the Jewish people have endured. The danger in revisiting the tragedies of generations past is that our rituals foster a distorted self-perception, a feeling of eternal victimization. Instead, we must remember because grief is an expression of love, because there is an urgent moral message in the stories of our suffering that we must hear today, and because we are drawn again and again, through our collective grief, into community.
