For instance, there is a person who has only one loaf of bread. He is traveling in a train and finds somebody who is hungry and in need of his bread. He himself is hungry too, and he has only one piece of bread. If he thinks that it is his dharma to give and starve, and is unhappy about it, he would do better not to give it, because it is no virtue. If he did it once, the next time he would surely not do it again because he suffered by it. As the virtue brought him unhappiness, this virtue will never develop in his character. That person alone is capable of renunciation who finds a greater satisfaction in seeing another with his piece of bread.
