Another aspect is duty. One considers that one has a duty to one's community, town, or country; one does some social work, one tries to do good to others and considers it one's duty. It may be that one has a duty towards one's parents; one may be looking after one's mother and sacrifice one's life for her, or for one's wife and children. There is great merit in this also. No doubt what speaks against it is that very often such lives are spoiled, and they have no chance to do anything worth while in the world; but if it were not for the dutiful the world would be devoid of love and affection. If the wife had no sense of duty towards her husband, nor the neighbor towards his friend, then they would be living like creatures of the lower creation. It is the sense of duty that makes man greater than other beings; that is why we admire it. Heroes who give their lives for their country are not doing a small thing. It is something great when a person gives his life for the sake of duty. Besides duty is a great virtue.
