Following this simile further, it is quite possible that, just as light waves may travel for millions of years before they reach any object, so thought waves may also travel hundreds of years before they meet an object with which they vibrate in unison. It is quite possible, therefore, that this atmosphere of ours is full of such thought pulsations, both good and evil. Every thought projected from every brain goes on pulsating, as it were, until it meets a fit object that will receive it. Any mind which is open to receive some of these impulses will take them immediately. So, when a man is doing evil actions, he has brought his mind to a certain state of tension and all the waves which correspond to that state of tension, and which may be said to be already in the atmosphere, will struggle to enter into his mind. That is why an evil-doer generally goes on doing more and more evil. His actions become intensified. Such, also will be the case with the doer of good; he will open himself to all the good waves that are in the atmosphere, and his good actions also will become intensified. We run, therefore, a twofold danger in doing evil: first, we open ourselves to all the evil influences surrounding us; secondly, we create evil which affects others, may be hundreds of years hence. In doing evil we injure ourselves and others also. In doing good we do good to ourselves and to others as well; and, like all other forces in man, these forces of good and evil also gather strength from outside.
According to Karma-Yoga, the action one has done cannot be destroyed until it has borne its fruit; no power in nature can stop it from yielding its results. If I do an evil action, I must suffer for it; there is no power in this universe to stop or stay it. Similarly, if I do a good action, there is no power in the universe which can stop its bearing good results. The cause must have its effect; nothing can prevent or restrain this. Now comes a very fine and serious question about Karma-Yoga — namely, that these actions of ours, both good and evil, are intimately connected with each other. We cannot put a line of demarcation and say, this action is entirely good and this entirely evil. There is no action which does not bear good and evil fruits at the same time. To take the nearest example: I am talking to you, and some of you, perhaps, think I am doing good; and at the same time I am, perhaps, killing thousands of microbes in the atmosphere; I am thus doing evil to something else. When it is very near to us and affects those we know, we say that it is very good action if it affects them in a good manner. For instance, you may call my speaking to you very good, but the microbes will not; the microbes you do not see, but yourselves you do see. The way in which my talk affects you is obvious to you, but how it affects the microbes is not so obvious. And so, if we analyse our evil actions also, we may find that some good possibly results from them somewhere. He who in good action sees that there is something evil in it, and in the midst of evil sees that there is something good in it somewhere, has known the secret of work.
But what follows from it? That, howsoever we may try, there cannot be any action which is perfectly pure, or any which is perfectly impure, taking purity and impurity in the sense of injury and non-injury. We cannot breathe or live without injuring others, and every bit of the food we eat is taken away from another’s mouth. Our very lives are crowding out other lives. It may be men, or animals, or small microbes, but some one or other of these we have to crowd out. That being the case, it naturally follows that perfection can never be attained by work. We may work through all eternity, but there will be no way out of this intricate maze. You may work on, and on, and on; there will be no end to this inevitable association of good and evil in the results of work.
The second point to consider is, what is the end of work? We find the vast majority of people in every country believing that there will be a time when this world will become perfect, when there will be no disease, nor death, nor unhappiness, nor wickedness. That is a very good idea, a very good motive power to inspire and uplift the ignorant; but if we think for a moment, we shall find on the very face of it that it cannot be so. How can it be, seeing that good and evil are the obverse and reverse of the same coin? How can you have good without evil at the same time? What is meant by perfection? A perfect life is a contradiction in terms. Life itself is a state of continuous struggle between ourselves and everything outside. Every moment we are fighting actually with external nature, and if we are defeated, our life has to go. It is, for instance, a continuous struggle for food and air. If food or air fails, we die. Life is not a simple and smoothly flowing thing, but it is a compound effect. This complex struggle between something inside and the external world is what we call life. So it is clear that when this struggle ceases, there will be an end of life.
What is meant by ideal happiness is the cessation of this struggle. But then life will cease, for the struggle can only cease when life itself has ceased. We have seen already that in helping the world we help ourselves. The main effect of work done for others is to purify ourselves. By means of the constant effort to do good to others we are trying to forget ourselves; this forgetfulness of self is the one great lesson we have to learn in life. Man thinks foolishly that he can make himself happy, and after years of struggle finds out at last that true happiness consists in killing selfishness and that no one can make him happy except himself. Every act of charity, every thought of sympathy, every action of help, every good deed, is taking so much of self-importance away from our little selves and making us think of ourselves as the lowest and the least, and, therefore, it is all good. Here we find that Jnâna, Bhakti, and Karma — all come to one point. The highest ideal is eternal and entire self-abnegation, where there is no “I,” but all is “Thou”; and whether he is conscious or unconscious of it, Karma-Yoga leads man to that end. A religious preacher may become horrified at the idea of an Impersonal God; he may insist on a Personal God and wish to keep up his own identity and individuality, whatever he may mean by that. But his ideas of ethics, if they are really good, cannot but be based on the highest self-abnegation. It is the basis of all morality; you may extend it to men, or animals, or angels, it is the one basic idea, the one fundamental principle running through all ethical systems.
You will find various classes of men in this world. First, there are the God-men, whose self-abnegation is complete, and who do only good to others even at the sacrifice of their own lives. These are the highest of men. If there are a hundred of such in any country, that country need never despair. But they are unfortunately too few. Then there are the good men who do good to others so long as it does not injure themselves. And there is a third class who, to do good to themselves, injure others. It is said by a Sanskrit poet that there is a fourth unnamable class of people who injure others merely for injury’s sake. Just as there are at one pole of existence the highest good men, who do good for the sake of doing good, so, at the other pole, there are others who injure others just for the sake of the injury. They do not gain anything thereby, but it is their nature to do evil.
Here are two Sanskrit words. The one is Pravritti, which means revolving towards, and the other is Nivritti, which means revolving away. The “revolving towards” is what we call the world, the “I and mine”; it includes all those things which are always enriching that “me” by wealth and money and power, and name and fame, and which are of a grasping nature, always tending to accumulate everything in one centre, that centre being “myself”. That is the Pravritti, the natural tendency of every human being; taking everything from everywhere and heaping it around one centre, that centre being man’s own sweet self. When this tendency begins to break, when it is Nivritti or “going away from,” then begin morality and religion. Both Pravritti and Nivritti are of the nature of work: the former is evil work, and the latter is good work. This Nivritti is the fundamental basis of all morality and all religion, and the very perfection of it is entire self-abnegation, readiness to sacrifice mind and body and everything for another being. When a man has reached that state, he has attained to the perfection of Karma-Yoga. This is the highest result of good works. Although a man has not studied a single system of philosophy, although he does not believe in any God, and never has believed, although he has not prayed even once in his whole life, if the simple power of good actions has brought him to that state where he is ready to give up his life and all else for others, he has arrived at the same point to which the religious man will come through his prayers and the philosopher through his knowledge; and so you may find that the philosopher, the worker, and the devotee, all meet at one point, that one point being self-abnegation. However much their systems of philosophy and religion may differ, all mankind stand in reverence and awe before the man who is ready to sacrifice himself
