What is Individualisation?
Individualisation, is the capacity to take up all experiences and organise them around the divine centre. 
One can't merge one's ego in the Divine before becoming completely individualised.
The Reason for Individualisation
In creating the universe as it was, the Will was an individual projection—individual, you understand, a scattering: instead of being a unity containing all, it was a unity made of innumerable small unities which are individualisations, that is, things that feel themselves separated. And the very fact of being separated from all others is what gives you the feeling that you are an individual. Otherwise you would have the feeling that you were a fluid mass. For example, instead of being conscious of your external form and of everything in your being which makes of you a separate individuality, if you were conscious of the vital forces which move everywhere or of the inconscient that is at the base of all, you would have the feeling of a mass moving with all kinds of contradictory movements but which could not be separated from each other; you would not have the feeling of being an individual at all: you would have the feeling of something like a vibration in the midst of a whole. Well, the original Will was to form individual beings capable of becoming conscious once again of their divine origin. Because of the process of individualisation one must feel separate if one is to be an individual. The moment you are separated, you are cut off from the original consciousness, at least apparently, and you fall into the inconscient. For the only thing which is the Life of life is the Origin, if you cut yourself off from that, consciousness naturally is changed into unconsciousness. And then it is due to this very unconsciousness that you are no longer aware of the truth of your being.... It is a process. You cannot argue whether it is inevitable or evitable; the fact is it is like that.
Nature of Individualisation
First one must become a conscious, well-knit, individualised being, who exists in himself, by himself, independently of all his surroundings, who can hear anything, read anything, see anything without changing. He receives from outside only what he wants to receive; he automatically refuses all that is not in conformity with his plan and nothing can leave an imprint on him unless he agrees to receive the imprint. Then one begins to become an individuality! When one is an individuality, one can make an offering of it.
Individuality Before Self-Offering
So long as one does not exist, one can give nothing. And for the separative ego to disappear, as you say, one must be able to give oneself entirely, totally without reservation. And to be able to give oneself, one must first exist. And to exist one must be individualised.
When the Fruit is Ripe..
And then, later, one offers all this to the Divine. Years of work are needed. You must not only...(silence)... become conscious of yourself, conscious in all details, but you must organise what you call "yourself" around the psychic centre, the divine centre of your being, so that it would make a single, coherent, fully conscious being. And as this divine centre is itself already consecrated (Mother makes a gesture of offering) entirely to the Divine, if everything is organised harmoniously around it, everything is consecrated to the Divine. And so, when the Divine thinks it proper, when the time has come, when the work of individualisation is complete, then the Divine gives you permission to let your ego merge in Him, to live henceforward only for the Divine.
The Awakening of Responsibility
Surely, One has a big responsibility, it is to fulfil a special mission that one is born upon earth. Only, naturally, the psychic being must have reached a certain degree of development; otherwise it could be said that it is the whole earth which has the responsibility. The more conscious and individualised one becomes, the more should one have the sense of responsibility. But this is what happens at a given moment; one begins to think that one is here not without reason, without purpose. One realises suddenly that one is here because there is something to be done and this something is not anything egoistic. This seems to me the most logical way of entering upon the path—all of a sudden to realise, "Since I am here, it means that I have a mission to fulfil. Since I have been endowed with a consciousness, it is that I have something to do with that consciousness—what is it?"
The Individualistic and Communal Impulses
The Dangers From the Collective
To be individualised in a collectivity, one must be absolutely conscious of oneself. And of which self?—the Self which is above all intermixture, that is, what I call the Truth of your being. And as long as you are not conscious of the Truth of your being, you are moved by all kinds of things, without taking any note of it at all. Collective thought, collective suggestions are a formidable influence which act constantly on individual thought. And what is extraordinary is that one does not notice it. One believes that one thinks "like that", but in truth it is the collectivity which thinks "like that". The mass is always inferior to the individual. Take individuals with similar qualities, of similar categories, well, when they are alone these individuals are at least two degrees better than people of the same category in a crowd. There is a mixture of obscurities, a mixture of unconsciousness, and inevitably you slip into this unconsciousness. To escape this there is but one means: to become conscious of oneself, more and more conscious and more and more attentive.
Collective Prerequisite for Its Progress
The Safety That It Provides
To live without a fortress is extremely difficult—people have the feeling that they are not living, that they are not individualised, that they are floating about. It is extremely difficult to live in something infinitely vast, moving, constantly changing, perpetually in progress, not to be held by anything to which one can cling, saying "I am this; this is my way of thinking." It is very difficult, one must not try it too soon; there are those whose mind gets deranged by it.
The Need for Education
It's indispensable for you to have a frame in which you can learn how to form yourself. If you did your work of individualisation, of total formations, by yourself, all alone in a corner, nothing at all would be asked of you. But you don't do it, you wouldn't do it, there's not a single child who would do it, he wouldn't even know how to do it, where to begin. If a child were not taught how to live, he could not live, he wouldn't know how to do anything, anything. I don't want to speak about disgusting details, but even the most elementary things he would not do properly if he were not taught how to do them. Therefore, one must, step by step... That is to say, if everyone had to go through the whole experience needed for the formations of an individuality, he would be long dead before having begun to live! This is the contribution—accumulated through centuries—of those who have had the experience and tell you, "Well, if you want to go quickly, to know in a few years what has been learnt through centuries, do this!" Read, learn, study and then, in the material field, you will be taught to do this in this way, that in that way, this again in this way (gestures). Once you know a little, you can find your own method, if you have the genius for it! But first one must stand on one's own feet and know how to walk. It is very difficult to learn it all alone. It's like that for everyone. One must form oneself. Therefore, one needs education. 
An individualised mind is something extremely rare, which comes only after a long education; 
Birds of a same Feather…
There are many souls upon earth, human beings... Obviously, those who have a certain culture, a certain development, a certain individualisation gather together usually: instinctively they get together, form groups. And so one can find in space and time a number—not considerable but still sufficiently large—of cultured beings who are united, but one must not believe that this gives the exact proportion of the culture and development of human beings. It is only like a sort of foam that has been brought up and is on the surface. But even among these latter, even among these beings who are already a selection, there is hardly one in a thousand who is a truly individual being, conscious of himself, united with his psychic being, governed by his inner law and, consequently, almost if not totally free from external influences; for, being conscious, when these influences come, he sees them: those that seem to him to harmonise with his inner development and normal growth he accepts; those which are opposed he refuses. And so, instead of being a chaos—or in any case a frightful mixture—they are organised beings, individual, conscious of themselves, walking through life knowing where they want to go and how they want to.
The True Individual and the Limitation of Labels
When we speak of an individual we mean ordinarily an individualisation of mental, vital, physical being separate from all other beings, incapable of unity with them by its very individuality. If we go beyond these three terms of mind, life and body, and speak of the soul or individual self, we still think of an individualised being separate from all others, incapable of unity and inclusive mutuality, capable at most of a spiritual contact and soul-sympathy. It is therefore necessary to insist that by the true individual we mean nothing of the kind, but a conscious power of being of the Eternal, always existing by unity, always capable of mutuality. It is that being which by self-knowledge enjoys liberation and immortality.
The Purusha and His World-Material
Crystallization and De-crystallization in Individualisation
“..the suppleness needed to follow the movement of Becoming; suppleness, that is, the capacity for de-crystallisation—the whole period of life spent in individualisation is a period of conscious and deliberate crystallisation, which later has to be undone. Becoming a conscious and individual being is a constant crystallization—constant and deliberate—of all things; and afterwards one must make the opposite movement, constantly, and also, even more so, deliberately. At the same time, one must not lose the benefit, in the consciousness, of what one has acquired by individualisation.”
Individualisation of Animals
Except for very rare cases, the animals are not individualised and when they die they return to the spirit of the species.(The Mother; 6 August, 1966)
What is the Ego?
The ego was created for the work of individualisation; when the work is achieved, it is not unusual for the ego to accept its own dissolution.
...before speaking of merging one's ego in the Divine, one must first know a little what one is. The ego is there. Its necessity is that you become conscious, independent beings, individualised—I mean in the see of independent—that you may not be the public square where everything goes criss-cross! That you may exist in yourselves. That is why there is an ego. It is like that; that is why also there is a skin, like that... though truly, even physical forces pass through the skin. There is a vibration which goes a certain distance. But still, it's the skin that prevents us from blending into one another. 
In order to become a conscious, individualised being, one needs his ego; that is why it is there. It is only when one has realised his own individuality sufficiently, has become a conscious, independent being with its own reality, that he no longer needs the ego. And at that time one can make an effort to get rid of it.
Before Its Formation
“...the first state of your being is a state of an almost total mixture with all things from outside, and that there is almost no individualisation, that is, specialisation which makes you a different being. You are moved—a kind of form which is your physical being is moved—by all the common universal forces, vital forces or mental forces, which go through your form and put it in motion.
The Paradox of the Ego
The ego is what helps us to individualise ourselves and what prevents us from becoming divine. It is like that. Put that together and you will find the ego. Without the ego, as the world is organised, there would be no individual, and with the ego the world cannot become divine.
It’s the Helper and the Hurdle
Certainly, if one were to lose one's ego too soon, from the vital and mental point of view one would again become an amorphous mass. The ego is surely the instrument for individualisation, that is, until one is an individualised being, constituted in himself, the ego is an absolutely necessary factor. If one had the power of abolishing the ego ahead of time, one would lose one's individuality. But once the individuality has been formed, the ego becomes not only useless but harmful. And only then comes the time when it must be abolished. But naturally, as it has taken so much trouble to build you, it does not give up its work so easily, and it asks for the reward of its efforts, that is, to enjoy the individuality.
When we have passed beyond individualising, then we shall be real Persons. Ego was the helper; Ego is the bar.
So, for everyone—except for those who are born free, and this is obviously very rare—for everyone this state of reason, of effort, desire, individualisation and solid physical balance in accordance with the ordinary mode of living is indispensable to begin with, until the time one becomes a conscious being, when one must give up all these things in order to become a spiritual being.
...to begin with, a tremendous labour is required to individualise oneself, and afterwards one must demolish all that has been done in order to progress. (The Mother; 20 February, 1957)
When It’s Mastered
It’s not the Cause of Individuality
It is purposely, mind you, that I have not mentioned the ego as one of the causes of the sense of individuality. For the ego being a falsehood and an illusion, the sense of individuality would itself be false and illusory (as Buddha and Shankara affirm), whereas the origin of individualisation being in the Supreme Himself, the ego is only a passing deformation, necessary for the moment, which will disappear when its utility is over, when the Truth-Consciousness will be established.(The Mother; 3 March, 1951)

Diversity in Unity, That Leads to Unity in Diversity
And that is the great mystery of creation, for it is the same consciousness, the Consciousness is one. But the very moment this Consciousness manifests itself, exteriorises itself, deploys itself, it divides itself into innumerable fragments for the need of expansion, and each one of these fragmentations has been the beginning, the origin of an individual being. The origin of every individual form is the law of this form or the truth of this form. If there were no law, no truth of each form, there would be no possibility of individualisation. It would be something extending indefinitely; there would be perhaps points of concentration, assemblages, but no individual consciousness. Each form then represents one element in the changing of the One into the many. This multiplicity implies an innumerable quantity of laws, elements of consciousness, truths which spread out into the universe and finally become separate individualities. So the individual being seems constantly to go farther and farther away from its origin by the very necessity of individualisation. But once this individualisation, that is, this awareness of the inner truth is complete, it becomes possible, by an inner identification, to re-establish in the multiplicity the original unity; that is the raison d'être of the universe as we perceive it. The universe has been made so that this phenomenon may take place. The Supreme has manifested Himself to Himself so as to become aware of Himself.
Divine Life is a Practical Mutuality Founded in Essential Unity
The Psychic and Individualisation
The Evolution of the Psychic
This is what happens. Let us take a divine spark which, through attraction, through affinity and selection, gathers around it a beginning of psychic consciousness (this work is already very perceptible in animals—don't think you are exceptional beings, that you alone have a psychic being and the rest of creation hasn't. It begins in the mineral, it is a little more developed in the plant, and in the animal there is a first glimmer of the psychic presence). Then there comes a moment when this psychic being is sufficiently developed to have an independent consciousness and a personal will. And then after innumerable lives more or less individualised, it becomes conscious of itself, of its movements and of the environment it has chosen for its growth. Arriving at a certain state of perception, it decides—generally at the last minute of the life it has just finished upon earth—the conditions in which its next life will be passed. Here I must tell you a very important thing: the psychic being can progress and form itself only in the physical life and upon earth. As soon as it leaves a body, it enters into a rest which lasts for a more or less long time according to its own choice and its degree of development—a rest for assimilation, for a passive progress so to say, a rest for passive growth which will allow this same psychic being to pass on to new experiences and make a more active progress. But after having finished one life (which usually ends only when it has done what it wanted to do), it will have chosen the environment where it will be born, the approximate place where it will be born, the conditions and the kind of life in which it will be born, and a very precise programme of the experiences through which it will have to pass to be able to make the progress it wants to make.
The soul is the eternal essence at the centre of the psychic being. The soul is in fact like a divine spark which puts on many states of being of increasing density, down to the most material; it is inside the body, within the solar plexus, so to say. These states of being take form and develop, progress, become individualised and perfected in the course of many earthly lives and form the psychic being. When the psychic being is fully formed, it is aware of the consciousness of the soul and manifests it perfectly.
The essence of the soul is divine, but the soul (the psychic being) grows through all the forms of evolution; it becomes more and more individualised and increasingly conscious of itself and its origin. 
The Psychic and its Gradations
It is always pure. But it is either more or less individualised and independent in its action. What is psychic in the being is always pure, by its very definition, for it is that part of the being which is in contact with the Divine and expresses the truth of the being. But this may be like a spark in the darkness of the being or it may be a being of light, conscious, fully formed and independent. There are all the gradations between the two.(The Mother; 16 December, 1953)
The Growth of the Psychic Presence Into the Psychic Being
With regard to the evolution upwards, it is more correct to speak of the psychic presence than the psychic being. For it is the psychic presence which little by little becomes the psychic being. In each evolving form there is this presence, but it is not individualised. It is something which is capable of growth and follows the movement of the evolution. It is not a descent of the involution from above. It is formed progressively round the spark of Divine Consciousness which is meant to be the centre of a growing being which becomes the psychic being when it is at last individualised. It is this spark that is permanent and gathers round itself all sorts of elements for the formation of that individuality; the true psychic being is formed only when the psychic personality is fully grown, fully built up, round the eternal divine spark; it attains its culmination, its total fulfilment if and when it unites with a being or personality from above. 
The Progress of the Psychic Over Many Births
Rebirth and the Constancy of the Psychic Being
“...there is a common misconception about rebirth. People believe that it is they who are reincarnated, yet this is a palpable error, though it is true that parts of their being are amalgamated with others and so act through new bodies. Their whole being is not reborn, because of the simple fact that what they evidently mean by their "self" is not a real individualised entity but their exterior personality, the personality composed of the outward name and form. Hence it is wrong to say that A is reborn as B: A is a personality organically distinct from B and cannot be said to have reincarnated as B. You would be right only if you said that the same line of consciousness uses both A and B as the instruments of its manifestation. For, what does remain constant is the psychic being which is not the outward personality at all, but something deep within, something which is not the exterior name and form.”
Interdependence of the Earth and the Psychic Being
It is only upon earth that the psychic being gets its experiences to individualise itself. Hence there is an almost absolute interdependence between the psychic world and the earth. 
The Psychic Presence in the Vital World
Full Individualisation and the End of Psychic Progress
But this sort of progress has an end. There comes a time when the being is fully developed, fully individualised, fully master of itself and its destiny. When this being or one of these psychic beings has reached that stage and takes birth in a human being, that makes a very great difference: the human being, so to say, is born free. He is not tied to circumstances, to surroundings, to his origin and atavism, like ordinary people. He comes into the world with the purpose of doing something, with a work to carry out, a mission to fulfill. From this point of view his progress in growth has come to an end, that is, it is not indispensable for him to take birth again in a body. Till then rebirth is a necessity, for it is through rebirth that he grows; it is in the physical life and in a physical body that he gradually develops and becomes a fully conscious being. But once he is fully formed, he is free, in this sense that he can take birth or not, at will. So there, one kind of progress stops.
Organization to Develop a Particular Attitude to the Divine
The aim of the psychic being is to form an individual being, individualised, "personalised" around the divine centre. Normally, all the experiences of the external life (unless one does yoga and becomes conscious) pass without organising the inner being, while the psychic being organises these experiences serially. It wants to realise a particular attitude towards the Divine. Hence it looks for all favourable experiences in order to have the complete series of opportunities, so to say, which will allow it to realise this attitude towards the Divine. 
The Psychic in the Realm of Matter
If there were no psychic in Matter, it would not be able to have any direct contact with the Divine. And it is happily due to this psychic presence in Matter that the contact between Matter and the Divine can be direct and all human beings can be told, "You carry the Divine within you, and you have only to enter within yourself and you will find Him." It is something very particular to the human being or rather to the inhabitants of the earth. In the human being the psychic becomes more conscious, more formed, more conscious and more independent also. It is individualised in human beings. But it is a speciality of the earth. It is a direct infusion, special and redeeming, in the most inconscient and obscure Matter, so that it might once again awake through stages to the divine Consciousness, the divine Presence and finally to the Divine Himself. It is the presence of the psychic which makes man an exceptional being..
The Psychic Being and its Relationship With Truth
The soul individualises itself and progressively transforms itself into a psychic being. (The Mother; 28 July, 1960)
The Physical, Vital and Mental
The Importance of the Body in Individualisation
If your body were not made in the rigid form it is—for it is terribly rigid, isn't it?—well, if all that were not so fixed, if you had no skin, here, like this, solid, if externally you were the reflection of what you are in the vital and mental fields, it would be worse than being a jelly-fish! Everything would fuse into everything else, like this... Oh, what a mess it would be! That is why it was at first necessary to give a very rigid form. Afterwards we complain about it. We say, "The physical is fixed, it is a nuisance; it lacks plasticity, it lacks suppleness, it hasn't that fluidity which can enable us to merge into the Divine." But this was absolutely necessary, for without this... if you simply went out of your body (most of you can't do it because the vital being is hardly more individualised than the physical), if you came out of your body and went into the vital world, you would see that all things there intermingle, they are mixed, they divide; all kinds of vibrations, currents of forces come and go, struggle, try to destroy one another, take possession of each other, absorb each other, throw each other out... and so it goes on! But it is very difficult to find a real personality in all this. These are forces, movements, desires, vibrations.
The Individualisation of the Subtle Bodies
You know, when you sleep, the inner beings are not concentrated upon the body, they go out and become more or less independent—a limited independence, but independence all the same—and they go to dwell in their own domains. The mind more so, for it is hardly held within the body, it is only concentrated but not contained in the body. The vital also goes beyond the body, but it is more concentrated upon the body. The mind however is such a supple substance that it is sufficient to think about a person in order to be with that person, at least partially, mentally. If you think strongly of a place, a part of your mind is there; distance, so to say, does not exist. Of course, to have a mind centralised around the body requires good training. Few people have a mind with a well-defined form: it is like clouds which roll, come and go. Even to have a vital with a form similar to that of your physical body, an analogous form, it must be very much individualised, very much centralised. The mind still more; it must be completely individualised, centralised, organised around the psychic centre in order to have a definite form.
There are similar examples, for instance, among musicians. There are pianists who have individualised their hands and made them so wonderfully conscious that these hands are not decomposed—not the physical hands: the hands of the subtle physical and vital—they are not deposed, do not dissolve at the time of death. They remain as instruments to play the piano and always try to incarnate in the hands of someone playing the piano. I have known some cases of people who, as they were about to play, felt as though other hands entered into theirs and started playing really marvellously, in a way they could not have done themselves.
Individualisation of Vital Powers
(The Mother, 10 March, 1951)
“..to the individual vital plane there corresponds a cosmic vital world. When a human being is sufficiently developed he possesses an individualised vital being with organs of sight, hearing, smell, etc. So a person who has a well-developed vital being can see in the vital world with his vital sight, consciously and with the memory of what he has seen. This is what makes a vision.”
Individualisation of the Mental Being
But as soon as the mental being is formed, organised, individualised, and has become a personality, it does not depend, it no longer depends on the body for its existence, and it therefore survives the body. The earth's mental atmosphere is filled with beings, mental personalities which lead an entirely independent existence, even after the disappearance of the body; they can reincarnate in a new body when the soul, that is to say, the true Self, reincarnates, thus carrying with it the memory of its previous lives.
The Subconscient, Conscient and the Superconscient
Inconscient and Individualisation
The inconscient is not individualised and when you go down into the inconscient in yourself, it is the inconscient of matter. One can't say that each individual has his own inconscient, for that would already be a beginning of individualisation...
Transformation of the Inconscient
The light, the consciousness that comes down into this inconscient in order to transform it must necessarily be a consciousness that is close enough to be able to touch it. It is not possible to conceive of a light—the supramental light, for example—that would have the power to individualise the inconscient. But, through a conscious, individualised being, this light can be brought down into the inconscient and gradually make it conscious.
Death and Individualisation
The ordinary mass of men are so closely identified with their bodies that nothing of them survives when the physical disintegrates. Not that absolutely nothing survives—the vital and mental stuff always remains but it is not identical with the physical personality. What survives has not the clear impress of the exterior personality because the latter was content to remain a jumble of impulses and desires, a temporary organic unity constituted by the cohesion and coordination of bodily functions, and when these functions cease their pseudo-unity also naturally comes to an end. Only if there has been a mental discipline imposed on the different parts and they have been made to subserve a common mental ideal, can there be some sort of genuine individuality which retains the memory of its earthly life and so survives consciously. The artist, the philosopher and other developed persons who have organised, individualised and to a certain extent converted their vital being can be said to survive, because they have brought into their exterior consciousness some shadow of the psychic entity which is immortal by its very nature and whose aim is to progressively build up the being around the central Divine Will.
Death as an Aid to Individualisation and Evolution
It was the conditions of matter upon earth that made death indispensable. The whole sense of the evolution of matter has been a growth from a first state of unconsciousness to an increasing consciousness. And in this process of growth dissolution of forms became an inevitable necessity, as things actually took place. For a fixed form was needed in order that the organised individual consciousness might have a stable support. And yet it is the fixity of the form that made death inevitable. Matter had to assume forms; individualisation and the concrete embodiment of life-forces or consciousness-forces were impossible without it and without these there would have been lacking the first conditions of organised existence on the plane of matter. But a definite and concrete formation contracts the tendency to become at once rigid and hard and petrified. The individual form persisted as a too binding mould; it cannot follow the movements of the forces; it cannot change in harmony with the progressive change in the universal dynamism; it cannot meet continually Nature's demand or keep pace with her; it gets out of the current. At a certain point of this growing disparity and disharmony between the form and the force that presses upon it, a complete dissolution of the form is unavoidable. A new form must be created; a new harmony and parity made possible. This is the true significance of death and this is its use in Nature. But if the form can become more quick and pliant and the cells of the body can be awakened to change with the changing consciousness, there would be no need of a drastic dissolution, death would be no longer inevitable.
Death, Desire and Strife - The Trinity of Divided Living
Immortality - The Individualised Expression of the Universal Self
But this is not what Sri Aurobindo calls Immortality. Immortality is a life without beginning or end, without birth or death, which is altogether independent of the body. It is the life of the Self, the essential being of each individual, and it is not separate from the universal Self. And this essential being has a sense of oneness with the universal Self; it is in fact a personified, individualised expression of the universal Self and has neither beginning nor end, neither life nor death, it exists eternally and that is what is immortal. When we are fully conscious of this Self we participate in its eternal life, and we therefore become immortal.
The Individualisation of the Supermind
The individualisation of states of being which have so far never been conscious in man, that is to say, there are superposed states of consciousness, and there are new regions which have never yet been manifested on earth, and which Sri Aurobindo called supramental. It is that, this was the same idea. That is, one must go into the depths or the heights of creation which have never been manifested upon earth, and become conscious of that, and manifest it on earth. Sri Aurobindo called it the Supermind. I simply say these are states of being which were never yet conscious in man (that is, that man has so far never been aware of them). One must get identified with them, then bring them into the outer consciousness, and manifest them in action. 
The Ascent Towards Supermind
The Supramental Manifestation and its Individualisation
The consciousness is like a ladder: at each great epoch there has been one great being capable of adding one more step to the ladder and reaching a place where the ordinary consciousness had never been. It is possible to attain a high level and get completely out of the material consciousness; but then one does not retain the ladder, whereas the great achievement of the great epochs of the universe has been the capacity to add one more step to the ladder without losing contact with the material, the capacity to reach the Highest and at the same time connect the top with the bottom instead of letting a kind of emptiness cut off all connection between the different planes. To go up and down and join the top to the bottom is the whole secret of realisation, and that is the work of the Avatar. Each time he adds one more step to the ladder there is a new creation upon earth.... The step which is being added now Sri Aurobindo has called the Supramental; as a result of it, the consciousness will be able to enter the supramental world and yet retain its personal form, its individualisation and then come down to establish here a new creation. Certainly this is not the last, for there are farther ranges of being; but now we are at work to bring down the supramental, to effect a reorganisation of the world, to bring the world back to the true divine order. It is essentially a creation of order, a putting of everything in its true place; and the chief spirit or force, the Shakti active at present is Mahasaraswati, the Goddess of perfect organisation.
