Patanjali Yoga Sutras CHAPTER II - SADHANA PADA CONCENTRATION - ITS PRACTICE ॥ द्वितीयः साधनपादः ॥
- तपःस्वाध्यायेश्वरप्रणिधानानि क्रियायोगः ॥ १॥ tapahsvadhyayeshvarapranidhanani kriyayogah Mortification, study, and surrendering fruits of work to God are called Kriya Yoga. Those Samadhis with which we ended our last chapter are very difficult to attain; so we must take them up slowly. The first step, the preliminary step, is called Kriya Yoga. Literally this means work, working towards Yoga. The organs are the horses, the mind is the reins, the intellect is the charioteer, the soul is the rider, and this body is the chariot. The master of the household, the King, the Self of man, is sitting in this chariot. If the horses are very strong, and do not obey the reins, if the charioteer, the intellect, does not know how to control the horses, then this chariot will come to grief. But if the organs, the horses, are well controlled, and if the reins, the mind, are well held in the hands of the charioteer, the intellect, the chariot, reaches the goal. What is meant, therefore, by mortification? Holding the reins firmly while guiding this body and mind: not letting the body do anything it likes, but keeping them both in proper control. Study. What is meant by study in this case? Not study of novels, or fiction, or story books, but study of those books which teach the liberation of the soul. Then again this study does not mean controversial 54
Patanjali Yoga Sutras studies at all. The Yogi is supposed to have finished his period of controversy. He has had enough of all that, and has become satisfied. He only studies to intensify his convictions. Vada and Siddhanta. These are the two sorts of Scriptural knowledge, Vada (the argumentative) and Siddhanta (the decisive). When a man is entirely ignorant he takes up the first part of this, the argumentative fighting, and reasoning, pro and con.; and when he has finished that he takes up the Siddhanta, the decisive, arriving at a conclusion. Simply arriving at this conclusion will not do. It must be intensified. Books are infinite in number, and time is short; therefre this is the secret of knowledge, to take that which is essential. Take that out, and then try to live up to it. There is an old simile in India that if you place a cup of milk before a Raja Hamsa (swan) with plenty of water in it, he will take all the milk and leave the water. In that way we should take what is of value in knowledge, and leave the dross. All these intellectual gymnastics are necessary at first. We must not go blindly into anything. The Yogi has passed the argumentative stage, and has come to a conclusion, which is like the rocks, immovable. The only thing he now seeks to do is to intensify that conclusion. Do not argue, he say; if one forces arguments upon you, be silent. Do not answer any argument, but go away free, because arguments only disturb the mind. The only thing is to train the intellect, so what is the use of disturbing it any more. The intellect is but a weak instrument, and can give only knowledge limited by the senses; the Yogi wants to go beyond the senses; therefore the intellect is of no use to him. He is certain of this, and therefore is silent, and does not argue. Every argument throws his mind out of balance, creates a disturbance in the Chitta, and this 55
Patanjali Yoga Sutras disturbance is a drawback. These argumentations and searchings of the reason are only on the way. There are much higher things behind them. The whole of life is not for schoolboy fights and debating societies. By “surrendering the fruits of work to God” is to take to ourselves neither credit nor blame, but to give both up to the Lord, and be at peace. 2. समाधिभावनार्थः क्लेशतनूकरणार्थश्च ॥ २॥ samadhibhavanarthah kleshatanookaranarthashch (They are for) the practice of Samadhi and minimising the pain-bearing obstructions. Most of us make our minds like spoiled children, allowing them to do whatever they want. Therefore it is necessary that there should be constant practice of the previous mortifications, in order to gain control of the mind, and bring it into subjection. The obstructions to Yoga arise from lack of this control, and cause us pain. They can only be removed by denything the mind, and holding it in check, through these various means. 3. अविद्यास्मितारागद्वेषाभिनिवेशाः क्लेशाः ॥ ३॥ avidyasmitaragadveshabhiniveshah kleshaah The pain-bearing obstructions are - ignorance, egoism, attachment, aversion, and clinging to life. These are the five pains, the fivefold tie that binds us down. Of course ignorance is the mother of all the rest. She is the 56
Patanjali Yoga Sutras only cause of all our misery. What else can make us miserable? The nature of the Soul is eternal bliss. What can make it sorrowful except ignorance, hallucination, delusion; all this pain of the soul is simply delusion. 4. अविद्या क्षेत्रम् उत्तरेषां प्रसुप्ततनुविच्छिन्नोदाराणाम् ॥ ४॥ avidya kshetram uttareshan prasuptatanuvichchhinnodaranam Ignorance is the productive field of all them that follow, whether they are dormant, attenuated, overpowered, or expanded. Impressions are the cause of these, and these impressions exist in different degrees. There are the dormant. You often hear the expression “innocent as a baby,” yet in the baby may be the state of a demon or of a god which will come out by and by. In the Yogi these impressions, the Samskaras left by past actions, are attenuated; that is, in a very fine state, and he can control them, and not allow them to become manifest. Overpowered means that sometimes one set of impressions is held down for a while by those that are stronger, but they will come out when that repressing cause is removed. The last state is the expanded, when the Samskaras, having helpful surroundings, have attained to great activity, either as good or evil. 5. अनित्याशुचिदुःखानात्मसु नित्यशुचिसुखात्मख्यातिरविद्या ॥ ५॥ anityashuchiduhkanatmasu nityashuchisukhatmakhyatiravidya 57
Patanjali Yoga Sutras Ignorance is taking that which is non-eternal, impure, painful, and non-Self, for the eternal, pure, happy, Atman (Self). All these various sorts of impression have one source: ignorance. We have first to learn what ignorance is. All of us think that “I am the body,” and not the Self, the pure, the effulgent, the ever blissful, and that is ignorance. We think of man, and see man as body. This is the great delusion. 6. दृग्दर्शनशक्त्योरेकात्मतेवास्मिता ॥ ६॥ drigdarshanashaktyorekatmatevasmita Egoism is the identification of the seer with the instrument of seeing. The seer is really the Self, the pure one, the ever holy, the infinite, the immortal. That is the Self of man. And what are the instruments? The Chitta, or mind-stuff, the Buddhi, determinative faculty, the Manas, or mind, and the Indriyani, or sense organs. These are the instruments for him to see the external world, and the identification of the Self with the instruments is what is called the ignorance of egoism. We say “I am the mind, I am thought; I am angry, or I am happy.” How can we be angry, and how can we hate? We should identify ourselves with the Self; that cannot change. If it is unchangeable, how can it be one moment happy, and one moment unhappy? It is formless, infinite, omnipresent. What can change it? Beyond all law. What can affect it? Nothing in the universe can produce an effect on it, yet, through ignorance, we identify ourselves with the mind-stuff, and 58
Patanjali Yoga Sutras think we feel pleasure or pain. 7. सुखानुशयी रागः ॥ ७॥ sukhanushayi raagah Attachment is that which dwells on pleasure. We find pleasure in certain things, and the mind, like a current, flows towards them, and that, following the pleasure centre, as it were, is attachment. We are never attached to anyone in whom we do not find pleasure. We find pleasure in very queer things sometimes, but the definition is just the same; wherever we find pleasure, there we are attached. 8. दुःखानुशयी द्वेषः ॥ ८॥ duhkhanushayi dveshah Aversion is that which dwells on pain. That, which gives us pain we immediately seek to get away from. 9. स्वरसवाही विदुषोऽपि तथारूढोऽभिनिवेशः ॥ ९॥ svarasavahi vidushopi tatharoodho bhiniveshah Flowing through its own nature, and established even in the learned, is the clinging to life. This clinging to life you see manifested in every animal, and upon it many attempts have been made to build the theory of a future life, because men like their lives so much that they desire a future life also. Of course it goes without saying that 59
Patanjali Yoga Sutras this argument is without much value, but the most curious part of it is that, in Western Countries, the idea that this clinging to life indicates a possibility of a future life applies only to men, but does not include animals. In India this clinging to life has been one of the arguments to prove past experience and existence. For instance, if it be true that all our knowledge has come from experience, then it is sure that that which we never experienced we cannot imagine, or understand. As soon as chickens are hatched they begin to pick up food. Many times it has been seen where ducks have been hatched by hens, that, as soon as they come out of the eggs, they flew to water, and the mother thought they would be drowned. If experience be the only source of knowledge, where did these chickens learn to pick up food, or the ducklings that the water was their natural element? If you say it is instinct, it means nothing—it is simply giving it a word, but is no explanation. What is this instinct? We have many instincts in ourselves. For instance, most of you ladies play the piano, and remember, when you first learned, how carefully you had to put your fingers on the black and the white keys, one after the other, but now, after long years of practice, you can talk with your friends, and your hand goes on just the same. It has become instinct, it becomes automatic, but so far as we know, all the cases which we now regard as automatic are degenerated reason. In the language of the Yogi, instinct is involved reason. Discrimination becomes involved, and gets to be automatic Samskaras. Therefore it is perfectly logical to think that all we call instinct in this world is simply involved reason. As reason cannot come without experience, all instinct is, therefore, the result of past experience. Chickens fear the hawk, and ducklings love the water, and these are both the 60
Patanjali Yoga Sutras result of past experience, and these are both the result of past experience. Then the question is whether that experience belongs to a particular soul, or to the body simply, whether this experience which comes to the duck is the duck's forefather's experience, or the duck's own experience. Modern scientific menhold that it belongs to the body, but the Yogis hold that it is the experience of the soul, transmitted through the body. This is called the theory of reincarnation. We have seen that all of our knowledge, whether we call it perception or reason, or instinct, must come through that one channel called experience, and all that we know call instinct is the result of past experience, degenerated into instinct, and that instinct regenerates into reason again. So on throughout the universe, and upon this has been built one of the chief arguments for reincarnation, in India. The recurring experiences of various fears, in course of time, produce this clinging to life. That is why the child is instinctively afraid, because the past experience of pain is there. Even in the most learned men, who know that this body will go, and who say “never mind: we have hundreds of bodies; the soul cannot die”—even in them, with all their intellectual conviction, we still find this clinging to life. What is this clinging to life? We have seen that it has become instinctive. In the psychological language of Yoga if has become Samskaras. The Samskaras, fine and hidden, are sleeping in the Chitta. All these past experiences of death, all that which we call instinct, is experience become sub-conscious. It lives in the Chitta, and is not inactive, but is working underneath. These Chitta Vrttis, these mind-waves, which are gross, we can appreciate and feel; they can be more easily controlled, but what about these finer instincts? How can they be controlled? When I am angry 61
Patanjali Yoga Sutras my whole mind has become a huge wave of anger. feel it, see it, handle it, can easily manipulate it, can fight with it, but I shall not succeed perfectly in the fight until I can get down below. A man says something very harsh to me, and I begin to feel that I am getting heated, and he goes on until I am perfectly angry, and forget myself, identify myself with anger. When he first began to abuse me I still thought “I am going to be angry.” Anger was one thing and I was another, but when I became angry, I was anger. These feelings have to be controlled in the germ, the root, in their fine forms, before even we have become conscious that they are acting on us. With the vast majority of mankind the fine states of these passions are not even known, the state when they are slowly coming from beneath consciousness. When a bubble is rising from the bottom of the lake we do not see it, or even when it is nearly come to the surface; it is only when it bursts and makes a ripple that we know it is there. We shall only be successful in grappling with the waves when we can get hold of them in their fine casues, and until you can get hold of them, and subdue them before any become gross, there is no hope of conquering any passion perfectly. To control our passions we have to control them at their very roots; then alone shall we be able to burn out their very seed. As fried seeds thrown into the ground will never come up, so these passions will never arise. 10. ते प्रतिप्रसवहेयाः सूक्ष्माः ॥ १०॥ te pratiprasavaheyah sookshmah They, to-be-rejected-by-opposite-modifications, are fine. 62
Patanjali Yoga Sutras How are these fine Samskaras to be controlled? We have to begin with the big waves, and come down and down. For instance, when a big wave of anger has come into the mind, how are we to control that? Just by raising a big opposing wave. Think of love. Sometimes a mother is very angry with her husband, and while in that state the baby comes in, and she kisses the baby; the old wave dies out, and a new wave arises, love for the child. That suppresses the other one. Love is opposite to anger. So we find that by raising the opposite waves we can conquer those which we want to reject. Then, if we can raise in our fine nature those fine opposing waves, they will check the fine workings of anger beneath the conscious surface. We have seen now that all these instinctive actions first began as conscious actions, and became finer and finer. So, if good waves in the conscious Chitta be constantly raised, they will go down, become subtle, and oppose the Samskara forms of evil thoughts. 11. ध्यानहेयास्तद्वृत्तयः ॥ ११ ॥ dhyanaheyastadvrittayah By meditation, their modifications are to be rejected. Meditation is one of the great means of controlling the rising of these big waves. By meditation you can make the mind subdue these waves, and, if you go on practising meditation for days, and months, and years, until it has become a habit, until it will come in spite of yourself, anger and hatred will be controlled and checked. 63
Patanjali Yoga Sutras 12. क्लेशमूलः कर्माशयो दृष्टादृष्टजन्मवेदनीयः ॥ १२॥ kleshamoolah karmashayo drishtadrishtajanmavedaniyah The receptacle of works has its root in these pain-bearing obstructions, and their experience in this visible life, or in the unseen life. By the receptacle of works is meant the sum-total of these Samskaras. Whatever work we do, the mind is thrown into a wave, and, after the work is finished, we think the wave is gone. No. It has only become fine, but it is still there. When we try to remember the thing, it comes up again and becomes a wave. So it was there; if it had not been there, there would not have been memory. So, every action, every thought, good or bad, just goes down and becomes fine, and is there stored up. They are called pain-bearing obstructions, both happy and unhappy thoughts, because according to the Yogis, both, in the long run, bring pain. All happiness which comes from the senses will, eventually, bring pain. All enjoyment will make us thirst for more, and that brings pain as its result. There is no limit to man’s desires; he goes on desring, and when he comes to a point where desire cannot be fulfilled, the result is pain. Therefore the Yogis regard the sum-total of the impressions, good or evil, as pain-bearing obstructions; they obstruct the way to freedom of the Soul. It is the same with the Samskaras, the fine roots of all our works: they are the causes which will again bring effects, either in this life, or in the lives to come. In exceptional cases, when these Samskaras are very strong, they bear fruit quickly; exceptional acts of wickedness, or of 64
Patanjali Yoga Sutras
goodness, bring their fruits in this life. The Yogis even hold that men who are able to acquire a tremendous power of good Samskaras do not have to die, but, even in this life, can change their bodies into god-bodies. There are several cases mentioned by the Yogis in their books. These men change the very material of their bodies; they re-arrange the molecules in such fashion that they have no more sickness, and what we call death does not come to them. Why should not this be? The physiological meaning of foot is assimilation of energy from the sun. This energy has reached the plant, the plant is eaten by an animal, and the animal by us. The science of it is that we take so much energy from the sun, and make it part of ourselves. That being the case, why should there be only one way of assimilating energy? The plant’s way is not the same as ours; the earth’s process of assimilating energy differs from our own. But all assimilate energy in some form or other. The Yogis say that they are able to assimilate energy by the power of the mind alone, that they can draw in as much as they desire without recourse to the orindary methods. As a spider makes his net out of his own substance, and becomes bound in his net, and cannot go anywhere except along the lines of that net, so we have projected out of our own substance this net-work called the nerves, and we cannot work except through the channels of those nerves. The Yogi says we need not be bound by that. Similary, we can send electricity to any part of the world, but we have to send it by means of wires. Nature can send a vast mass of electricity without any wires at all. Why cannot we do the same? We can send mental electricity. What we call mind is very much the same as electricity. It is clear that this nerve fluid has some amount of electricity, because it is polarised, and it answers all electrical directions. We can 65
only send our electricity through these nerve channels. Why not send the mental electricity without this aid? The Yogi says it is perfectly possible and practicable, and that when you can do that you will work all over the universe. You will be able to work with anybody anywhere, without the help of any nervous system. When the soul is acting through these channels we say a man is living and when those channels die the man is said to be said. But when a man is able to act either with or without these channels, birth and death will have no meaning for him. All the bodies in the universe are made up of Tanmatras, and it is only in the arrangement of them that there comes a difference. If you are the arranger you can arrange that body in one way or another. Who makes up this body but you? Who eats the food? If another ate the food for you, you would not live long. Who makes the blood out of it? You, certainly. Who assimilates the blood, and sends it through the veins? You. Who creates the nerves, and makes all the muscles? You are the manufacturer, out of your own substance. You are the manufacturer of the body, and you live in it. Only we have lost the knowledge of how to make it. We have become automatic, degenerate. We have forgotten the process of manufacture. So, what we do automatically has again to be regulated. We are the creators and we have to regulate that creation, and as soon as we can do that we shall be able to manufacture just as we like, and then we shall have neither birth nor death, disease, or anything. 13. सति मूले तद्विपाको जात्यायुर्भोगाः ॥ १३॥ sati moole tadvipako jatyayurbhogah The root being there, the fruition comes (in the form 66
Patanjali Yoga Sutras of) species, life, and expression of pleasure and pain. The roots, the causes, the Samskaras being there, they again manifest, and form the effects. The cause dying down becomes the effect, and the effect becomes more subtle, and becomes the cause of the next effect. The tree bears a seed, and becomes the cause of the next tree, and so on. All our works now, are the effects of past Samskaras. Again, these Samskaras become the cause of future actions, and thus we go on. So this aphorism says that the cause being there, the fruit must come, in the form of species; one will be a man, another an angel, another an animal, another a demon. Then there are different effects in life; one man lives fifty years, another a hundred, and another dies in two years, and never attains maturity; all these differences in life are regulated by these past actions. One man is born, as it were, for pleasure; if he buries himself in a forest pleasure will follow him there. Another man, wherever he goes, pain follows him, everything becomes painful. It is all the result of their own past. According to the philosophy of the Yogis all virtuous actions bring pleasure, and all vicious actions bring pain. Any man who does wicked deeds is sure to reap the fruit of them in the form of pain. 14. ते ह्लादपरितापफलाः पुण्यापुण्यहेतुत्वात् ॥ १४॥ te hladaparitapafalah punyapunyahetutvat They bear fruit as pleasure or pain, caused by virtue or vice. 67
Patanjali Yoga Sutras 15. परिणामतापसंस्कारदुःखैर्गुणवृत्तिविरोधाच्च दुःखम् एव सर्वं विवेकिनः ॥ १५॥ parinamatapasanskaraduhkhairgunnavritti - virodhaccha duhkham eva sarvan vivekinah To the discriminating, all is, as it were, painful on account of everything bringing pain, either in the consequences, or in apprehension, or in attitude caused by impressions, also on account of the counter action of qualities. The Yogis say that the man who has discriminating powers, the man of good sense, sees through all these various things, which are called pleasure and pain, and knows that they are always equally distributed, and that one follows the other, and melts into the other; he sees that men are following an ignis fatuus all their lives, and never succeed in fulfilling their desires. There was never a love in this world which did not know decay. The great king Yudisthira once said that the most wonderful thing in life is that every moment we see people dying around us, and yet we think we shall never die. Surrounded by fools on every side, we think we are the only exceptions, the only learned men. Surrounded by all sorts of experiences of fickleness, we think our love is the only lasting love. How can that be? Even love is selfish, and the Yogi says that, in the end, we shall find that even the love of husbands and wives, and children and friends, slowly decays. Decadence seizes everything in this life. It is only when everything, even love, fails, that, with a flash, man finds out 68
Patanjali Yoga Sutras how vain, how dream-like is this world. Then he catches a glimpse of Vairagyam (renunciation), catches a glimpse of the beyond. It is only by giving up this world that the other comes; never through building on to this one. Never yet was there a great soul who had not to reject sense pleasures and enjoyments to become such. The cause of misery is the clash between difference forces of nature, one dragging one way, and another dragging another, rendering permanent happiness impossible. 16. हेयं दुःखम् अनागतम् ॥ १६॥ heyan duhkham anagatam The misery which is not yet come is to be avoided. Some Karma we have worked out already, some we are working out now in the present, and some is waiting to bear fruit in the future. That which we have worked out already is past and gone. That which we are experiencing now we will have to work out, and it is only that which is waiting to bear fruit in the future that we can conquer and control, so all our forces should be directed towards the control of that Karma which has not yet borne fruit. That is meant in the previous aphorism, when Patanjali says that these various Samskaras are to be controlled by counteracting waves. 17. द्रष्टृदृश्ययोः संयोगो हेयहेतुः ॥ १७॥ drashtridrishyayoh sanyogo heyahetuh The cause of that which is to be avoided is the 69
Patanjali Yoga Sutras
junction of the seer and the seen. Who is the seer? The Self of Man, the PuruSa. What is the seen? The whole of nature, beginning with the mind, down to gross matter. All this pleasure and pain arises from the junction between this PuruSa and the mind. The PuruSa, you must remember, according to this philosophy, is pure; it is when it is joined to nature, and by reflection, that it appears to feel either pleasure or pain. 18. प्रकाशक्रियास्थितिशीलं भूतेन्द्रियात्मकं भोगापवर्गार्थं दृश्यम् ॥ १८॥ prakashakriyasthitishilan bhootendriyatmakan bhogapavargarthan drishyam The experienced is composed of elements and organs, is of the nature of illumination, action and intertia, and is for the purpose of experience and release (of the experiencer). The experienced, that is nature, is composed of elements and organs—the elements gross and fine which compose the whole of nature, and the organs of the senses, mind, etc., and is of the nature of illumination, action, and intertia. These are what in Sanskrit are called Sattva (illumination), Rajas (action), and Tamas (darkness); each is for the purpose of experience and relase. What is the purpose of the whole of nature? That the PuruSa may gain experience. The PuruSa has, as it were, forgotten its mighty, godly, nature. There is a story that the king of the gods, Indra, once became a pig, wallowing in mire; he had a she pig, and a lot of baby pigs, and was very happy. Then some other angels saw his plight,
70
Patanjali Yoga Sutras and came to him, and told him, “You are the king of the gods, you have all the gods command. Why are you here?” But Indra said, “Let me be; I am all right here; I do not care for the heavens, while I have this sow and these little pigs.” The poor gods were at their wits’ end what to do. After a time they decided to slowly come and slay one of the little pigs, and then another, until they had slain all the pigs, and the sow too. When all were dead Indra began to weep and mourn. Then the gods ripped his pig body open and he came out of it, and began to laugh when he realised what a hideous dream he had had; he, the king of the gods, to have become a pig, and to think that the pig-life was the only life! Not only so, but to have wanted the whole universe to come into the pig life! The PuruSa, when it identifies itself with nature, forgets that it is pure and infinite. The PuruSa does not live; it is life itself. It does not exist; it is existence itself. The Soul does not know; it is knowledge itself. It is an entire mistake to say that the Soul lives, or knows, or loves. Love and existence are not the qualities of the PuruSa, but its essence. When they get reflected upon something you may call them the qualities of that something. But they are not the qualities of the PuruSa, but the essence of this great Atman, this Infinite Being, without birth or death, Who is established in His own glory, but appears as if become degenerate until if you approach to tell Him, “You are not a pig,” he begins to squeal and bite. Thus with us all in this Maya, this dream world, where it is all misery, weeping, and crying, where a few golden balls are rolled, and the world scrambles after them. You were never bound by laws, Nature never had a bond for you. That is what the Yogi tells you; have patience to learn it. And the Yogi shows how, by junction with this nature, and identifying itself 71
Patanjali Yoga Sutras with the mind and the world, the Purusa thinks itself miserable. Then the Yogi goes on to show that the way out is through experience. You have to get all this experience, but finish it quickly. We have placed ourselves in this net, and will have to get out. We have got ourselves caught in the trap, and we will have to work out our freedom. So get this experience of husbands and wives, and friends, and little loves, and you will get through them safely if you never forget what you really are. Never forget this is only a momentary state, and that we have to pass through it. Experience is the one great teacher—experiences of pleasure and pain—but know they are only experiences, and will all lead, step by step, to that state when all these things will become small, and the Purusa will be so great that this whole universe will be as a drop in the ocean, and will fall off by its own nothingness. We have to go through these experiences, but let us never forget the ideal. 19. विशेषाविशेषलिङ्गमात्रालिङ्गानि गुणपर्वाणि ॥ १९॥ visheshavisheshalinggamatralinggani gunnaparvani The states of the qualities are the defined, the undefined, the indicated only, and the signless. The system of Yoga is built entirely on the philosophy of the Sankhyas, as I told you in some of the previous lectures, and here again I will remind you of the cosmology of the Sankhya philosophy. According to the Sankhyas, nature is both the material and efficient cause of this universe. In this nature there are three sorts of materials, the Sattva, the Rajas, and the 72
