Strength comes from charity
A Christian mystic from India, Sadhu Sundar Singh, several years ago wanted to go into Tibet to evangelize. He hired a Tibetan guide to take him over the Himalayas. They had gone but a short distance when they became tired and sat on the snow and ice. Then Singh said, "I think I hear someone groaning in the abyss." The Tibetan said: "Well, what difference does it make? We're almost dead ourselves." Singh went down, found a man, and dragged him to the base of the Himalayas to a little village. Refreshed by his act of charity, he came back to find the Tibetan guide frozen to death on the ice.
