Taanit 21: All for the Best

The potential positive impact of the righteous. Beginning with Nachum Ish Gamzu, who was blind, and a 4-limb amputee, with boils, in a bed with its feet in water to keep away the ants, in a dilapidated building, no less. He knows the building won't fall on him. But when they take him out, it indeed falls on everything inside. But why did he suffer like this? The Gemara says he said - he brought it on himself with an act lacking in compassion that he couldn't fix. Note also that Nachum Ish Gamzu taught R. Akiva. Also, when the righteous receive a message in a dream. And for whom do miracles happen? The ordinary people who tick with extraordinary kindness, which have tremendous impact.
