Now the answer comes along three different lines. There are three great classes of facts, each of which contributes to the necessity; and each, foreseen by the Logos, is definitely prepared for as needing a particular manifestation.
The first of these lines arises from what I may perhaps call the nature of things. I remarked at the beginning of this lecture on the fact that our universe, our system, is part of a greater whole, not separate, not independent, not primary, in comparatively a low scale in the universe, our sun a planet in a vaster system. Now what does that imply? As regards matter, Prakṛiti, it implies that our system is builded out of matter already existing, out of matter already gifted with certain properties, out of matter that spreads through all space, and from which every Logos takes His materials, modifying it according to His own plan and according to His own will. When we speak of Mûlaprakṛiti, the root of matter, we do not mean that it exists as the matter we know. No philosopher, no thinker would dream of saying that that which spreads throughout space is identical with the matter of our very elementary solar system. It is the root of matter, that of which all forms of matter are merely modifications. What does that imply? It implies that our great Lord, who brought our solar system into existence, is taking matter which already has certain properties given to it by One yet mightier than Himself. In that matter three guṇas exist in equilibrium, and it is the breath of the Logos that throws them out of equilibrium, and causes the motion by which our system is brought into existence. There must be a throwing out of equilibrium, for equilibrium means Pralaya, where there is not motion, nor any manifestation of life and form. When life and form come forth, equilibrium must have been disturbed, and motion must be liberated by which the world shall be built. But the moment you grasp that truth you see that there must be certain limitations by virtue of the very material in which the Deity is working for the making of the system. It is true that when out of His system, when not conditioned and confined and limited by it, as He is by His most gracious will, it is true that He would be the Lord of that matter by virtue of His union with the mightier Life beyond; but when for the building of the world He limits Himself within His Mâyâ, then He must work within the conditions of those materials that limit His activity, as we are told over and over again.
Now when in the ceaseless interplay of Sattva, Rajas, and Tamas, Tamas has the ascendancy, aided and, as it were, worked by Rajas, so that they predominate over Sattva in the foreseen evolution, when the two combining overpower the third, when the force of Rajas and the inertia and stubbornness of Tamas, binding themselves together, check the action, the harmony, the pleasure-giving qualities of Sattva, then comes one of the conditions in which the Lord comes forth to restore that which had been disturbed of the balanced interworking of the three guṇas and to make again such balance between them as shall enable evolution to go forward smoothly and not be checked in its progress. He re-establishes the balance of power which gives orderly motion, the order having been disturbed by the co-operation of the two in contradistinction to the third. In these fundamental attributes of matter, the three guṇas, lies the first reason of the need for Avatâras.
The second need has to do with man himself, and now we come back in both the second and the third to that question of good and evil, of which I have already spoken. I´shvara, when He came to deal with the evolution of man—with all reverence I say it—had a harder task to perform than in the evolution of the lower forms of life. On them the law is imposed and they must obey its impulse. On the mineral the law is compulsory; every mineral moves according to the law, without interposing any impulse from itself to work against the will of the One. In the vegetable world the law is imposed, and every plant grows in orderly method according to the law within it, developing steadily and in the fashion of its order, interposing no impulse of its own. Nay, in the animal world—save perhaps when we come to its highest members—the law is still a force overpowering everything else, sweeping everything before it, carrying along all living things. A wheel turning on the road might carry with it on its axle the fly that happened to have settled there; it does not interpose any obstacle to the turning of the wheel. If the fly comes on to the circumference of the wheel and opposes itself to its motion, it is crushed without the slightest jarring of the wheel that rolls on, and the form goes out of existence, and the life takes other shapes.
So is the wheel of law in the three lower kingdoms. But with man it is not so. In man I´shvara sets himself to produce an image of Himself, which is not the case in the lower kingdoms. As life has evolved, one force after another has come out, and in man there begins to come out the central life, for the time has arrived for the evolution of the sovereign power of will, the self-initiated motion which is part of the life of the Supreme. Do not misunderstand me—for the subject is a subtle one; there is only one will in the universe, the will of I´shvara, and all must conform itself to that will, all is conditioned by that will, all must move according to that will, and that will marks out the straight line of evolution. There may be swerving neither to the right hand nor to the left. There is one will only which in its aspect to us is free, but inasmuch as our life is the life of I´shvara Himself, inasmuch as there is but one Self and that Self is yours and mine as much as His—for He has given us His very Self to be our Self and our life—there must evolve at one stage of this wondrous evolution that royal power of will which is seen in Him. And from the A´tmâ within us, which is Himself in us, there flows forth the sovereign will into the sheaths in which the A´tmâ is as it were held. Now what happens is this: force goes out through the sheaths and gives them some of its own nature, and each sheath begins to set up a reflection of the will on its own account, and you get the "I" of the body which wants to go this way, and the "I" of passion or emotion which wants to go that way, and the "I" of the mind which wants to go a third way, and none of these ways is the way of the A´tmâ, the Supreme. These are the illusory wills of man, and there is one way in which you may distinguish them from the true will. Each of them is determined in its direction by external attraction; the man's body wants to move in a particular way because something attracts it, or something else repels it: it moves to what it likes, to what is congenial to it, it moves away from that which it dislikes, from that from which it feels itself repelled. But that motion of the body is but motion determined by the I´shvara outside, as it were, rather than by the I´shvara within, by the kosmos around and not by the Self within, which has not yet achieved its mastery of the kosmos. So with the emotions or passions: they are drawn this way or that by the objects of the senses, and the "senses move after their appropriate objects"; it is not the "I," the Self, which moves. And so also with the mind. "The mind is fickle and restless, O Kṛiṣhṇa, it seems as hard to curb as the wind," and the mind lets the senses run after objects as a horse that has broken its reins flies away with the unskilled driver. All these forces are set up; and there is one more thing to remember. These forces reinforce the râjasic guṇa and help to bring about that predominance of which I spoke; all these reckless desires that are not according to the one will are yet necessary in order that the will may evolve and in order to train and develop the man.
Do you say why? How would you learn right if you knew not wrong? How would you choose good if you knew not evil? How would you recognise the light if there were no darkness? How would you move if there were no resistance? The forces that are called dark, the forces of the Râkshasas, of the Asuras, of all that seem to be working against I´shvara—these are the forces that call out the inner strength of the Self in man, by struggling with which the forces of A´tmâ within the man are developed, and without which he would remain in Pralaya for evermore. It is a perfectly stagnant pool where there is no motion, and there you get corruption and not life. The evolution of force can only be made by struggle, by combat, by effort, by exercise, and inasmuch as I´shvara is building men and not babies, He must draw out men's forces by pulling against their strength, making them struggle in order to attain, and so vivifying into outer manifestation the life that otherwise would remain enfolded in itself. In the seed the life is hidden, but it will not grow if you leave the seed alone. Place it on this table here, and come back a century hence, and, if you find it, it will be a seed still and nothing more. So also is the A´tmâ in man ere evolution and struggle have begun. Plant your seed in the ground, so that the forces in the ground press on it, and the rays of the sun from outside make vibrations that work on it, and the water from the rain comes through the soil into it and forces it to swell—then the seed begins to grow; but as it begins to grow it finds the earth around. How shall it grow but by pushing at it and so bringing out the energies of life that are within it? And against the opposition of the ground the roots strike down, and against the opposition of the ground the growing point mounts upward, and by the opposition of the ground the forces are evolved that make the seed grow, and the little plant appears above the soil. Then the wind comes and blows and tries to drag it away, and, in order that it may live and not perish, it strikes its roots deeper and gives itself a better hold against the battering force of the wind, and so the tree grows against the forces which try to tear it out. And if these forces were not, there would have been no growth of the root. And so with the root of I'shvara, the life within us; were everything around us smooth and easy, we would remain supine, lethargic, indifferent. It is the whip of pain, of suffering, of disappointment, that drives us onward and brings out the forces of our internal life which otherwise would remain undeveloped. Would you have a man grow? Then don't throw him on a couch with pillows on every side, and bring his meals and put them into his mouth, so that he moves not limb nor exercises mind. Throw him on a desert, where there is no food nor water to be found; let the sun beat down on his head, the wind blow against him; let his mind be made to think how to meet the necessities of the body, and the man grows into a man and not a log. That is why there are forces which you call evil. In this universe there is no evil; all is good that comes to us from I´shvara, but it sometimes comes in the guise of evil that, by opposing it, we may draw out our strength. Then we begin to understand that these forces are necessary, and that they are within the plan of I´shvara. They test evolution, they strengthen evolution, so that it does not take the next step onward till it has strength enough to hold its own, one step made firm by opposition before the next is taken. But when, by the conflicting wills of men, the forces that work for retardation, to keep a man back till he is able to overcome them and go on, when they are so reinforced by men's unruly wishes that they are beginning, as it were, to threaten progress, then ere that check takes place, there is reinforcement from the other side: the presence pf the Avatâra of the forces that threaten evolution calls forth the presence of the Avatâra that leads to the progress of humanity.
We come to the third cause. The Avatâra does not come forth without a call. The earth, it is said, is very heavy with its load of evil, "Save us, O supreme Lord," the Devas come and cry. In answer to that cry the Lord comes forth. But what is this that I spoke of purposely by a strange phrase to catch your attention, that I spoke of as an Avatâra of evil? By the will of the one Supreme, there is one incarnated in form who gathers up together the forces that make for retardation, in order that, thus gathered together, they may be destroyed by the opposing force of good, and thus the balance may be re-established and evolution go on along its appointed road. Devas work for joy, the reward of Heaven. Svarga is their home, and they serve the Supreme for the joys that there they have. Râkshasas also serve Him, first for rule on earth, and power to grasp and hold and enjoy as they will in this lower world. Both sides serve for reward, and are moved by the things that please.
And in order, as our time is drawing to a close, that I may take one great example to show how these work, let me take the mighty one, Râvana of Lanka,[6] that we may give a concrete form to a rather difficult and abstruse thought. Râvana, as you all know, was the mighty intelligence, the Râkshasa, who called forth the coming of Shrî Râma. But look back into the past, and what was he? Keeper of Viṣhṇu's heaven, door-keeper of the mighty Lord, devotee, bhakta, absolutely devoted to the Lord. Look at his past, and where do you find a bhakta of Mahâdeva more absolute in devotion than the one who came forth later as Râvana? It was he who cast his head into the fire in order that Mahâdeva might be served. It is he in whose name have been written some of the most exquisite stotras, breathing the spirit of completest devotion; in one of them, you may remember—and you could scarcely carry devotion to a further point—it is in the mouth of Râvana words are put appealing to Mahâdeva, and describing Him as surrounded by forms the most repellent and undesirable, surrounded on every side by pisâchas and bhûtas,[7] which to us seem but the embodiment of the dark shadows of the burning ghat, forms from which all beauty is withdrawn. He cries out in a passion of love:
Better wear pisâcha-form, so we
Evermore are near and wait on Thee.
