A rabbi named Kalonymous Shapiro was imprisoned in the Warsaw Ghetto between 1941-1943. He wrote a journal in the evenings, and buried it shortly before he was deported to a death camp. In it he records the his mounting losses.
He describes his family being taken away, his community, his neighbors. His pain reaches a peak as he writes of God crying in the heavens, with His tears carrying such power that if one of them were to escape from heaven to earth, it would destroy the world.
