Every religion preaches that the essence of all morality is to do good to others. And why? Be unselfish. And why should I? Some God has said it? He is not for me. Some texts have declared it? Let them; that is nothing to me; let them all tell it. And if they do, what is it to me? Each one for himself, and somebody take the hindermost — that is all the morality in the world, at least with many. What is the reason that I should be moral? You cannot explain it except when you come to know the truth as given in the Gita: “He who sees everyone in himself, and himself in everyone, thus seeing the same God living in all, he, the sage, no more kills the Self by the self.” Know through Advaita(Non-Dualism) that whomsoever you hurt, you hurt yourself; they are all you. Whether you know it or not, through all hands you work, through all feet you move, you are the king enjoying in the palace, you are the beggar leading that miserable existence in the street; you are in the ignorant as well as in the learned, you are in the man who is weak, and you are in the strong; know this and be sympathetic. And that is why we must not hurt others. That is why I do not even care whether I have to starve, because there will be millions of mouths eating at the same time, and they are all mine. Therefore I should not care what becomes of me and mine, for the whole universe is mine, I am enjoying all the bliss at the same time; and who can kill me or the universe? Herein is morality. Here, in Advaita(Non-Dualism) alone, is morality explained. The others teach item but cannot give you its reason. Then, so far about explanation.
What is the gain? It is strength. Take off that veil of hypnotism which you have cast upon the world, send not out thoughts and words of weakness unto humanity. Know that all sins and all evils can be summed up in that one word, weakness. It is weakness that is the motive power in all evil doing; it is weakness that is the source of all selfishness; it is weakness that makes men injure others; it is weakness that makes them manifest what they are not in reality. Let them all know what they are; let them repeat day and night what they are. Let them suck it in with their mothers’ milk, this idea of strength — I am He, I am He. This is to be heard first — etc. And then let them think of it, and out of that thought, out of that heart will proceed works such as the world has never seen. What has to be done? Ay, this Advaita(Non-Dualism) is said by some to be impracticable; that is to say, it is not yet manifesting itself on the material plane.
If you want to be great materially, believe that you are so. I may be a little bubble, and you may be a wave mountain-high, but know that for both of us the infinite ocean is the background, the infinite Brahman is our magazine of power and strength, and we can draw as much as we like, both of us, I the bubble and you the mountain-high wave. Believe, therefore, in yourselves. The secret of Advaita is: Believe in yourselves first, and then believe in anything else. In the history of the world, you will find that only those nations that have believed in themselves have become great and strong. In the history of each nation, you will always find that only those individuals who have believed in themselves have become great and strong. Here, to India, came an Englishman who was only a clerk, and for want of funds and other reasons he twice tried to blow his brains out; and when he failed, he believed in himself, he believed that he was born to do great things; and that man became Lord Clive, the founder of the Empire. If he had believed the Padres and gone crawling all his life — “O Lord, I am weak, and I am low” — where would he have been? In a lunatic asylum. You also are made lunatics by these evil teachings. I have seen, all the world over, the bad effects of these weak teachings of humility destroying the human race. Our children are brought up in this way, and is it a wonder that they become semi-lunatics?
This is teaching on the practical side. Believe, therefore, in yourselves, and if you want material wealth, work it out; it will come to you. If you want to be intellectual, work it out on the intellectual plane, and intellectual giants you shall be. And if you want to attain to freedom, work it out on the spiritual plane, and free you shall be and shall enter into Nirvana, the Eternal Bliss. But one defect which lay in the Advaita was its being worked out so long on the spiritual plane only, and nowhere else; now the time has come when you have to make it practical. It shall no more be a Rahasya, a secret, it shall no more live with monks in caves and forests, and in the Himalayas.
