When Arjuna had picked himself a little bit, the Lord rebuked him and said, 'How is it that this delusion has come to you? It is unworthy of a warrior like you.' But even then Arjuna stuck to his first position, refused to fight and said, 'If in order to get it, I have to slay elders and other relations, I do not want not only a kingdom on this earth but even the delights of paradise. My mind gropes in darkness. I do not know where my duty lies. I put myself into your hands. Please guide me.'
Finding that Arjuna was bewildered and aspired after knowledge, Krishna had pity on him and proceeded to explain things to him: 'Your sorrow is for nothing, and you utter words about wisdom without understanding. You have evidently forgotten the distinction between the body and the embodied soul. The soul never dies; but the body passes through childhood, youth and age and perishes in the end. The body is born but the soul is birthless and unchanging. It ever was, is now and will be there for all time to come. For whom then do you grieve? Your grief arises from a delusion. You look upon these Kauravas as your own, but you are aware that their bodies will come to an end. And as for the souls which inhabit these bodies, no one can destroy them. The soul cannot be wounded by weapons, burned by fire, dried by the wind or drowned in water. Then again, consider this from the standpoint of your duty as a warrior with an army under his command. If you refuse to fight this righteous war, the consequences will be the very reverse of what you expect and you will become an object of ridicule. You have always enjoyed the reputation of being a brave man. But if now you withdraw from the battle you will be supposed to have been driven from it by fear. If it were part of your duty to flee in the face of danger, disgrace would not matter, but if you retire from battle now, you will have failed to discharge your duty, and people will be justified in condemning your flight.
'Thus far, I have tried to reason out things, draw a distinction between the body and the soul and remind you of your duty, as a warrior. But let me now explain Karmayoga (the method of action). A practitioner of Karmayoga never comes to harm. It has nothing to do with chopping logic. It is something to be translated into action and experience. An ounce of practice is more profitable than tons of argumentation. And this practice too must not be vitiated by speculation about its fruit. Literalists perform Vedic rites directed to the acquisition of material rewards. If one rite does not yield the expected fruit, they have recourse to another, and being disappointed once more, they take up a third. And thus they suffer from utter mental confusion. As a matter of fact, it is up to us to do our duty without wasting a single thought on the fruits of our action. To fight is the duty you have to discharge at present. Gain or loss, defeat or victory, is not in your power. Why should you carry the needless burden of thinking about them and be like the dog who walks under a cart and imagines that it is being drawn by himself and not by the bullocks? Defeat and victory, heat and cold, pleasure and pain come to a man in turn and he must put up with them. Without worrying about the fruit of action, a man must devote himself to the performance of his duty with an evenness of temper. This is yoga, or skill in action. The success of an act lies in performing it, and not in its result, whatever it is. Therefore be calm and do your duty clear of consequences.'
On hearing all this Arjuna said, 'The course of conduct you have mapped for me seems to be beyond my capacity. Not to worry about defeat or victory, not to waste a thought on the result, how can one attain such an evenness of temper and steadfastness in spirit? How does a man with such attainments behave, and how are we to recognize him?'
The Lord replied, 'O king, one who renounces all the cravings which torment the heart and derives his contentment from within himself is said to be a sthitaprajna or samadhistha (one stable in spirit). He is unruffled in adversity, and he does not hanker after happiness. Pleasure and pain are felt through the five senses. Therefore this wise man draws his senses away from sense objects even as a tortoise draws in his limbs. The tortoise withdraws into his shell when he apprehends danger. But in the case of human beings sense objects are ready to attack the senses at all times; therefore their senses must always be drawn in, and they should be ever ready to fight against sense objects. This is the real battle. Some people resort to self- mortification and fasting as weapons of defence against sense objects. These measures have their limited use. The senses do not make for sense objects so long as a man is fasting, but fasting alone does not destroy his relish for them. On the other hand that relish may be heightened when the fast is broken, and a man can get rid of it only with the grace of God. The senses are so powerful that they drag a man behind them by force if he is not on his guard. Therefore a man must always keep them under control. This end he can achieve only if he turns his eyes inward, realizes God Who resides in his heart and devoted to Him. One who thus looks upon Me as His goal and surrenders his all to Me, keeping his senses in control, is a yogi stable in spirit. On the other hand if a man is not master of his senses, he is always musing on the objects of sense and conceives an attachment for them, so that he can hardly think of anything else. From this attachment arises desire; and when the desire is thwarted he gets angry. Anger drives him nearly mad. He cannot understand what he is about. He thus loses his memory, behaves in a disorderly manner and comes to an ignoble end. When a man's senses rove at will, he is like a rudderless ship which is at the mercy of the gale and is broken to pieces on the rocks. Men should therefore abandon all desires and restrain their senses, so that these do not indulge in undesirable activity. The eyes then will look straight and that too only at holy objects; the ears will listen to hymns in praise of God or to cries of distress; hands and feet will be engaged in service. Indeed all the organs of sense and of action will be employed in helping a man to do his duty and making him a fit recipient of the grace of God. And once the grace of God has descended upon him, all his sorrows are at an end. As snow melts in the sunshine, all pain vanishes when the grace of God shines upon him and he is said to be stable in spirit. But if a man is not stable-minded, how can he think good thoughts ? Without good thoughts there is no peace, and without peace there is no happiness. Where a stable-minded man sees things clear as daylight, the unstable man distracted by the turmoil of the world is as good as blind. On the other hand what is pure in the eyes of the worldly wise looks unclean to and repels the stable-minded man. Rivers continuously flow into the sea, but the sea remains unmoved; in the same way all sense objects come to the yogi, but he always remains calm like the sea. Thus one who abandons all desires, is free from pride and selfishness and behaves as one apart, finds peace. This is the condition of a perfect man of God, and he who is established therein even at the final hour is saved (lit set free, mukta).'
