The story is told of Rabbi Aryeh Levin, the famed tzaddik of Jerusalem, who once spotted a young soldier on a short furlough from the army. The rabbi knew the young man from the neighborhood in Geula, and so he crossed the street in order to extend his hand in greeting. “Shalom Aleichem,” said the venerable sage. “Please come to my home. I would very much like to drink tea with you and hear about your activities.”
The young soldier seemed uncomfortable.
“I don’t think it’s right for me to come visit you,” he said. “I don’t wear a kippa anymore.”
Rabbi Levin, in his black hat and black kaftan, smiled warmly at the young man and took his hand in his own.
“Don’t you see?,” he said, “I’m a very short man. I see you, but I cannot look up so high as to notice as to whether you are wearing a kippa. But I can see your heart – and your heart is big and kind, and that’s what counts.
You are also a soldier placing your life at risk for all of us in Israel. Please drink tea with me; your kippa is probably bigger than mine."
