When we take a pitcherful of water from the sea it has its weight, but when we take a dip into the sea itself a thousand pitchersful of water flow above our head, and we do not feel their weight. We have to carry the pitcher of self with our strength; and so, while on the plane of selfishness pleasure and pain have their full weight, on the moral plane they are so much lightened that the man who has reached it appears to us almost superhuman in his patience under crushing trails, and his forbearance in the face of malignant persecution.
