It is ... hope that sustained the late Rabbi Hugo Gryn even in a concentration camp. In 1944, the German army had moved into his hometown of Berehoyo, in what was then Czechoslovakia, and deported his family to Auschwitz. There his father took precious margarine rations and hardened them to make Chanukah candles.
"Papa," his son said to him, "you need these to eat; you must keep your strength; you must stay alive."
"My son," he replied, "our experience here has taught us that you can live two weeks without food, two days without water. You can't live two minutes without hope."
