Now let us try to understand more clearly why it was that the ancient man of science was taught that the first step to true knowledge, or wisdom, was the unfolding of the Self. What is life or consciousness – for the two terms are synonymous? It is the power to answer to vibrations, the power to respond – that is consciousness. Evolution is the unfolding of a continually increasing power to respond. The whole universe is full of the vibrations of Íshvara, of God. He sustains and moves the whole. Consciousness is the power in us to answer to those vibrations. All powers lie hidden within us as the oak tree lies hidden in the acorn. But it is in the process of evolution that the sapling slowly grows out of the seed. In Eternity, in the Now, all is existent, perfect; in Time only is there succession, the unfolding of one thing after another. In the changeless Point everything is present: Space is but the field for diverse sequences. Hence Time and Space are the basic illusions, and are yet the fundamental conditions of thinking. Keep, I pray you, that definition of consciousness in mind, for it will govern the remainder of our study.

The Self in man, being in the image of God, is triple as the Self, the Divine, is triple. I need not stop to argue this. You know it from that great literature which lies at the foundation of all Hindu Philosophy. Whether you speak in abstract terms and say with the Upanishad that Brahman is threefold, whether you speak of Him as Sat-chit-ânanda, or whether, instead of using philosophical, abstract terms, you say He is manifest as Íshvara in the Trimûrti as Mahâdeva, Vishnu and Brahmâ, it matters not. You may take the concrete form or the abstract, the fundamental idea is the same: that the Divine Self in manifestation is triple, and therefore in every great religion God is spoken of as a Trinity. If this were not so, the relationship between God and man would remain for ever unintelligible, for man shows a triplicity as he evolves. The human reflection of that triple Divine Self is the triple Self in man.

One by one are the Divine aspects unfolded as manifestation proceeds. The lowest, if I may dare to use such a term, is the aspect which is first brought into activity for the building of the universe. So also in man the intelligence awakens and becomes active, the lowest aspect of the human Self. That is the reflection of Brahmâ, of the Universal Mind, the creative energy from which all comes forth; and you may find in yourselves, as you evolve, that creative faculty of imagination which, working at present in subtle matter, will, when man is perfect, work in grosser matter as well; for the imaginative power in man is the reflection of the power that in God created the universe. Brahmâ meditated, and all forms came forth; and in the creative power of mind lies every possibility of form. So in man is later evolved the next aspect, that of A'nanda, where unity is recognised instead of diversity. Chit, in man, is the intelligence that knows, that separates and divides and analyses, and it has to do with the multiplicity of forms and with their inter-relations; A'nanda is the wisdom that realises the unity of all things, and that accomplishes union, thus finding the joy that lies at the very heart of life; last of all in human evolution, is developed the third and highest aspect of Deity, Self-Existence, the Unity that lies beyond union, and this can be developed in man only because man is one with the Eternal in his nature. By this evolution, in ages to come, through the countless kalpas that lie in front, Íshvara after Íshvara arises, each as the fruitage of a universe, to carry on still more mightily the will of the "One without a second," and to manifest something of that perfection to the whole of the then manifested nature. Such, very roughly, is the course of human evolution into divinity, and this is carried on by races succeeding one another; as we come to the higher Root-races of man, to those that we speak of as the Fifth, in which we are, the Sixth, that shall succeed us, and the Seventh that finishes this cycle of human evolution, we learn that the characteristic of each of these three Root-races is that each gradually develops that aspect of God which belongs to it in the due sequence of evolution. The Fifth is developing the aspect of Chit, Intelligence, the mind is being evolved, and all the progress of modern science, so marked in our own days, is but part of the fruitage of that evolution, of that growth of intelligence which looks on the outer world as not itself – as the Not-Self – and seeks to study and understand it. The characteristic attributes belonging to the evolution of the two following races are even now to be reached by special methods, by individuals who are willing to take the pains to make the required sacrifices. That which we know as Yoga is the method by which evolution is quickened in the individual, and all the powers of the Self, up to the threshold of divinity, may by it be brought into manifestation in the man of the present. That is why Yoga training was necessary for the ancient scientist; he must develop in himself the three aspects of God, if he were to understand them as manifested in the universe around him.

Now, at our own stage of evolution, it is specially the life of Brahmâ – or the Brahmâ aspect of God – with which the human mind is coming into touch, because the mind in man is the reflection of the universal mind in Kosmos. That life is the life that is the force in the atom, that vivifies every atom, nay, that brings the atom into existence, as we shall see, and remains during the whole of the growth of the universe as the fundamental life that keeps those atoms as active particles building up innumerable forms. Only as the life of Brahmâ, the aspect of Brahmâ, is developed in the human Self will man be able to study the workings of that life in the atomic forms that are filled by it; and it is very significant that some of the greatest problems of modern science are now turning on the nature of the atom, and that scientists are asking, what is it? Is it matter or force? Is it a particle or a vortex? Never will that question be answered with certainty until man has developed in himself the power to respond to the life that thrills in the atom, until, developing intelligence within himself to the fullest point, he is able to answer by that intelligence to the vibrations of the atomic life outside him. We have defined consciousness as the power to answer to vibrations, and if man is to measure life, if he is to know the underlying causes of phenomena, he must develop in himself the power to respond to that life outside him; and in the perfection of human intelligence – the reflection of the Brahmâ aspect of God – lies the only possibility of solution for this much debated problem in science. I said it was significant, for this problem belongs to the Fifth race, and the Western world is at present peopled largely by the fifth sub-race of the great Fifth. Thus it takes to the very highest point the concrete mind of man, that marvellous activity of the intellect, that swift and yet patient study, bringing about the achievements that modern science is performing. All these are a testimony of the truth of the ancient teaching that sub-race after sub-race arises, each one with its own work to do, and we should look on the work of each sub-division of humanity as good in itself: each should not be regarded as an isolated and hostile expression, but as part of the Divine manifestation, expressing that portion which it is destined to express.

Looking thus, then, on the problem of the life that exists in the atom, we find that in order to understand it, we must develop the pure intellect in man; but to understand the life that clothes itself in organic forms, to unravel the secrets which will explain to us why one is formed thus and another thus, the next great aspect of the Self must be developed within us – that of the all-pervading life of Vishnu, that sustains the world as the mighty supporter of everything, the basis, the foundation of the whole. There alone is unifying energy and there the root from which all divisions have arisen; only as we realise this aspect of unifying energy in the Self will the secrets of organised forms in nature unravel themselves before our eyes. This work is that of the Sixth Root-race, and those who would ante-date their evolution must develop Sixth-race powers in themselves by Yoga. Remains one mightier problem, subtlest and most difficult of all, that of the life of the human spirit, of man evolving into God. The mysteries of that life may only be understood when the human Self, which comes forth from the Father of all – from the mighty One who is sometimes the Destroyer, sometimes the Creator, but always the Regenerator, the name that includes them both, Mahâdeva, the mighty God who is Sat, Existence – has developed the aspect of Sat, of pure Existence, thus becoming the triple Unity, a Logos, an Íshvara. That is the work of the Seventh Root-race, and when that is accomplished, then only will the final problems of the human spirit lie open before our gaze.

The scientific man of antiquity, then, began by that self-attention, unfolding in himself one by one all those potentialities under a suitable Guru, passing from step to step till he reached the highest, and ever worshipping the Mahâguru, the Guru of the universe. Having unfolded his highest powers, he began to study life, life in its outpouring, not life in its manifold and veiled manifestations in the lower worlds. Hence the lofty point at which he started, no less than the arising of Íshvara enveloped in Mâyâ.

What is Íshvara? What is Mâyâ? There is the first great problem. Let us reverently address ourselves to it. The philosophers of India have answered these questions in different ways, each one containing part of the eternal truth. Íshvara is that mighty centre of consciousness that exists unchanged in the bosom of the One Existence. There are innumerable such Centres of Consciousness, of which you may remember your own Svâmi Subba Rao wrote as existing in the bosom of the One Existence. Íshvara in manifestation is like a lamp, a light enclosed in a shade. Íshvara, enveloped in Mâyâ, brings forth a universe and is enclosed, as it were, in the universe of which He is the Light. Breaking the shade, the light shines forth in every direction. Dissolving the universe, He still remains. The centre remains, but the circumference that circumscribed it is gone. So is that mighty centre when the universe vanishes; He alone remains, holding His centre unshaken in the very act of merging in, expanding into, the Infinite, the Absolute, the Super-Consciousness, the One. Let us think of Him as an eternal centre of self-consciousness, able to merge in super-consciousness and to again limit Himself to self-consciousness.

What, then, is Mâyâ? Mâyâ is prepared in every case by the merging in Íshvara of the whole of the universe which is come to its ending. As one loka rolls up and merges in the one above it, all forms in the loka thus merged disappear, but the consciousness that ensouled those forms does not vanish; a modification of consciousness remains, a modification expressing itself by a vibratory power – not a vibration, but a power to vibrate in a particular way; and though the form vanishes as the loka is merged in the one above it – because the matter disappears, being disintegrated into finer matter – in consciousness there remains the power to vibrate in the way in which it had vibrated in the grosser matter, and power persists although the forms caused by such vibrations disappear, for lack of material sufficiently coarse to respond to such vibrations. As one region passes into the next, this process is repeated over and over and over again, and loka after loka vanishes. The forms are gone, the vibrations are gone, only the modifications in consciousness capable of giving rise to similar vibrations remain until finally, when Íshvara – whose consciousness was the one consciousness in the universe, whose life was the one life, who supported every form, who made the possibility of every separated existence – gathers up His universe into Himself ere He merges Himself in the One, everything has vanished that we know as form, nothing remains save the centre of consciousness. There remains in Íshvara the power of vibrating in particular fashions, resulting from the evolution of His universe, in endless multiplicity of vibrations; when He merges Himself in the One Existence all has vanished as form, but powers remain in these subtle modifications, preserved in that unchangeable centre in the mightiness of the One Life. Is that only a dream?

There was a great teacher, Vâsiṣhtha. He taught Râmâ, as you will remember, and in the record of his teaching there are hints on some of the mysteries of life. If you keep what I have now said in mind, if I have succeeded by the clumsy words which are all that the human tongue can utter on these great problems, in clarifying at all your thoughts, then just listen to that same thought as expressed by Sûryadeva, when he was speaking of the same thing – the ending and the new beginning of a universe. We have only to add to what I have already said, that when Íshvara arises in order that a new universe may be formed, He throws His life into these modifications that had apparently disappeared, and the Mâyâ in which He arises, enveloped and circumscribed, is His own re-vivified memory, which can never be separated from Himself; He draws in His consciousness, under the impulse of the Great Breath, limiting it to self-consciousness, and turning His attention to the contents of that self-consciousness, its powers start into activity, and that is Mâyâ. So it is written: "Thereafter, Thou, O Lord, intent on [maintaining] the reign of night, fixed within the Self, having indrawn that order of things, [or universe.]… To-day, Thou hast awakened, and art most joyfully desirous of again throwing out [manifesting] the universe in mighty gradations [hierarchies of beings]." [Yoga Vâsiṣhtha, lxxxvii, 7, 8.] These nights and days are the "Nights and Days of Brahmâ," the inbreathing and outbreathing of the One Existence, and Mâyâ is this indrawn "order of things" that remains fixed through the Night, and starts forth as Íshvara awakens at the coming of Day. That is Mâyâ and if you take up the definitions given in the different schools, you will find that this includes and illumines every one of them, that it shows you what is meant by illusion, and explains to you what is implied in dreaming. The joyful throwing out into manifestation of all the powers that are remembered by Íshvara the moment His attention is turned to His own Self, that memory-prompted "desire" which arises in the bosom of the Eternal, is the root of the coming universe. Now this thought will prove to you the key of much ancient teaching. You have, in the Universal Mind full of ideas which are not yet concreted into phenomena, the world of ideas of Plato, the invisible world of the Hebrew Kabbalah; in every great teaching you find the same thought expressed. If, instead of being fettered by words, as for the most part we are, and if, instead of repeating phrases that carry with them no idea in the mind of the repeater, we would try to read the thought that underlies the words, we should find the Hindu philosophy in every modern philosophy that is worthy of the name, and see the traces of ancient India in Greece and in Rome, in Germany and in the England of to-day.

What is the next stage? The Life-Breath goes forth. Íshvara, the Centre of all, enveloped in Mâyâ sends forth His breath; as that vibrating breath falls on the enveloping Mâyâ, Mâyâ becomes Prakriti, or Matter – rather, perhaps, Mûlaprakriti, the root of matter. As that breath, with its triple vibratory force falls on this matter, it throws it into three modifications, or "attributes" – Tamas, inertia, or better, stability; Rajas, activity, vigour; Sattva, a difficult word to translate: I am inclined to translate it as Harmony; for this reason, that wherever there is pleasure, Sattva is present. Without harmony no pleasure can anywhere exist. All pleasure is due to harmonious vibration, and that quality of harmonious inter-related vibrations is the quality that Sattva gives to matter. These three fundamental qualities of matter – answering to three fundamental modifications in the consciousness of Íshvara – inertia, activity, and harmony, these are the famous three Gunas without which Prakriti cannot manifest. Fundamental, essential, and unchangeable, they are present in every particle in the manifested universe, and according to their combinations is the nature of each particle.
