It expresses itself outwardly in an exceptionally kindly behaviour. He will not hurt others unnecessarily. He feels that one of the best pieces of advice he can give others is: "Be kind." In this way you abrase your own egoism and show forth something--just an echo--of this love which emanates from the indwelling spiritual self. The cost in thus weakly and briefly identifying yourself with others is little: the gain in moral growth is large. When your duties, activities, or responsibilities in life call for critical judgement of any person, that is allowable. But when you fall into it for the sake of idle gossip or, what is worse, when you are nastily censorious, slanderously back-biting, for the sake of malice, that is unkind and unpardonable. Above his own deliberate willing or wishing, quite spontaneously and impulsively, a feeling of pure love begins to well up within him. It is unconnected with physical or egoistic causes, for all those who touch his orbit benefit by it. It does not stop flowing if they are foolish or ugly, sinful or deformed, unclean or disagreeable.
