Another aspect of duty is the duty to our fellow-creatures; to one's co-workers, to the friends and acquaintances with whom one comes in contact in everyday life, with whom one does not have the feeling of older or younger, or any difference. We have a duty towards them. In the first place, to study the psychology of their nature; if we have to teach them, not to teach them as a teacher; if we help them, not to help them as a benefactor; whatever help we give them, to do it in such a way that even we ourselves do not know about it. That is the best way of serving. For even to do good is most difficult if we do not know how to do it. If we were able to win the affection of our fellow-men and to do some little service unassumingly, without the thought of appreciation or return, we have certainly performed a religious action.
