To ignite a soul

Kalman the shamash lights candles in the shul every afternoon. Boruch the butcher offers to buy this privilege, but Kalman does not desire money. Eventually, on Rabbi Yehudah Leib Assad's advice, Kalmen sells Boruch the right to light candles in the shul. Years later, Kalman and Boruch realize that they have both greatly benefited from Rabbi Assad's wise advice.
