"The only thing which IS necessary is that you should do your duty. The past is past, there is no use worrying about it. Try, in bearing your karma, to develop in yourselves courage, endurance and various other good qualities and then let it go. Fulfil all the duties that are cast upon you m this strange play of life, and you will be doing all that is required of you. This, at least, is of infinite importance, since upon it depends your future. Now you have to get into that point of view. It IS not easy, because around us are people by the thousand who are taking the play seriously and thinking of it as the real life It is not so much what they say to you and do to you (although that counts) that causes the difficulty, it is the immense, the incessant pressure of public opinion."
