Rabbi Mendel of Vorki required surgery on his finger. Although no anesthetics were available, Rabbi Mendel calmly sat through the operation without a sound.

After the operation, the doctor remarked how astounded he was for someone to be so calm. "He reacted as if it were not his finger. He felt no pain whatsoever."

Rabbi Mendel observed: "He doesn't understand. When a person comes and tells me his financial difficulties, even if he does not always act as properly as he should, I feel much more pain and suffering than when they operated on my finger."
