The iron which cannot be broken by hammers can be melted by fire. Love is fire; kindness is its chief expression; and if a person has developed this sufficiently in his heart, he can sooner or later change an enemy into a friend. It is mostly unkindness on one's own part that causes enmity all around; and one blames enemies and becomes horrified at their number, then blames the world and its nature and its life; and when the creation has been proved blameworthy in a person's mind, then how can the Creator be kept free from blame? Then that man feels that he alone is blameless, and all else is blameworthy; and life becomes a torture to him; he thinks it is not worth living. He becomes self-righteous, and everybody seems to be against him.
