It is that which prevents our being sociable, being kind. It is this that makes us unhappy. Have you known what it is to give your meal to another and to go without yourself? It gives a happiness that no dinner eaten by yourself can give. Have you known what it is to give your coat to another and do without it yourself? It gives a joy that the satisfaction of your own wants cannot give you. Even that perfect peace and calm which is the eternal life is in man and can be attained by man.
