We will use this article (especially, the section called "The Tapasya of Love") as a source for understanding the concept of Love, how to gradually get rid of hatred and start loving things around us. Only after understanding and feeling Love can one grasp the concept of God as something extremely intimate to oneself.
For the benefit of readers, I am reproducing the portion of the above article dealing with love:
Of all austerities the most difficult is the austerity of feelings and emotions, the tapasya of love.
Indeed, in the domain of feelings, more perhaps than in any other, man has the sense of the inevitable, the irresistible, of a fatality that dominates him and which he cannot escape. Love (or at least what human beings call love) is particularly regarded as an imperious master whose caprice one cannot elude, who strikes you according to his fancy and forces you to obey him whether you will or not. In the name of love the worst crimes have been perpetrated, the greatest follies committed.
And yet men have invented all kinds of moral and social rules in the hope of controlling this force of love, of making it amenable and docile. But these rules seem to have been made only to be broken; and the restraint they impose on its free activity merely increases its explosive power. For it is not by rules that the movements of love can be disciplined. Only a greater, higher and truer power of love can subdue the uncontrollable impulses of love. Only love can rule over love by enlightening, transforming and exalting it. For here too, more than anywhere else, control does not consist of suppression and abolition but of transmutation - a sublime alchemy. This is because, of all the forces at work in the universe, love is the most powerful, the most irresistible. Without love the world would fall back into the chaos of inconscience.
Consciousness is indeed the creatrix of the universe, but love is its saviour. Conscious experience alone can give a glimpse of what love is, of its purpose and process. Any verbal transcription is necessarily a mental travesty of something which eludes all expression in every way. Philosophers, mystics, occultists, have all tried to define love, but in vain. I have no pretension of succeeding where they have failed. But I wish to state in the simplest possible terms what in their writings takes such an abstract and complicated form. My words will have no other aim than to lead towards the living experience, and I wish to be able to lead even a child to it.
Love is, in its essence, the joy of identity; it finds its ultimate expression in the bliss of union. Between the two lie all the phases of its universal manifestation.
At the beginning of this manifestation, in the purity of its origin, love is composed of two movements, two complementary poles of the urge towards complete oneness. On one hand there is the supreme power of attraction and on the other the irresistible need for absolute self-giving. No other movement could have better bridged the abyss that was created when in the individual being consciousness was separated from its origin and became unconsciousness.
What had been projected into space had to be brought back to itself without, however, annihilating the universe which had thus been created. That is why love burst forth, the irresistible power of union.
It brooded over the darkness and the inconscience; it was scattered and fragmented in the bosom of unfathomable night. And then began the awakening and the ascent, the slow formation of Matter and its endless progression. It is indeed love, in a corrupted and darkened form, that is associated with all the impulses of physical and vital Nature, as the urge behind all movement and all grouping, which becomes quite perceptible in the plant kingdom. In trees and plants, it is the need to grow in order to obtain more light, more air, more space; in flowers, it is the offering of their beauty and fragrance in a loving efflorescence. Then, in animals, it is love that lies behind hunger and thirst, the need for appropriation, expansion, procreation, in short, behind every desire, whether conscious or not. And among the higher species, it is in the self-sacrificing devotion of the female to her young. This brings us quite naturally to the human race in which, with the triumphant advent of mental activity, this association reaches its climax, for it has become conscious and deliberate. Indeed, as soon as terrestrial development made it possible, Nature took up this sublime force of love and put it at the service of her creative work by linking and mixing it with her movement of procreation. This association has even become so close, so intimate, that very few human beings are illumined enough in their consciousness to be able to dissociate these movements from each other and experience them separately. In this way, love has suffered every degradation, it has been debased to the level of the beast.
From then on, too, there clearly appears in Nature's works the will to rebuild, by steps and stages and through ever more numerous and complex groupings, the primordial oneness. Having made use of the power of love to bring two human beings together to form the biune group, the origin of the family, after having broken the narrow limits of personal egoism, changing it into a dual egoism, Nature, with the appearance of children, brought forth a more complex unit, the family. And in course of time, with multifarious associations between families, individual interchanges and mingling of blood, larger groupings were formed: clans, tribes, castes, classes, leading to the creation of nations. This work of group formation proceeded simultaneously in the various parts of the world, crystallising in the different races. And little by little, Nature will fuse these races too in her endeavour to build a real and material foundation for human unity.
In the consciousness of most men, all this is the outcome of chance; they are not aware of the existence of a global plan and take circumstances as they come, for better or for worse according to their temperament: some are satisfied, others discontented.
Among the contented, there is a certain category of people who are perfectly adapted to Nature's ways: these are the optimists. For them the days are brighter because of the nights, colours are vivid because of the shadows, joy is more intense because of suffering, pain gives a greater charm to pleasure, illness gives health all its value; I have even heard some of them say that they are glad to have enemies because it made them appreciate their friends all the more. In any case, for all these people, sexual activity is one of the most enjoyable of occupations, satisfaction of the palate is a delight of life that they cannot go without; and it is quite normal to die since one is born: death puts an end to a journey which would become tedious if it were to last too long.
In short, they find life quite all right as it is and do not care to know whether it has a purpose or a goal; they do not worry about the miseries of others and do not see any need for progress.
Never try to "convert" these people; it would be a serious mistake. If they were unfortunate enough to listen to you, they would lose the balance they have without being able to find a new one. They are not ready to have an inner life, but they are Nature's favourites; they have a very close alliance with her, and this realisation should not be needlessly disturbed.
To a lesser degree, and above all, in a less durable way, there are other contented people in the world whose contentment is due to the magic effect of love. Each time an individual breaks the narrow limitations in which he is imprisoned by his ego and emerges into the open air, through self-giving, whether for the sake of another human being or his family, his country or his faith, he finds in this self-forgetfulness a foretaste of the marvellous delight of love, and this gives him the impression that he has come into contact with the Divine. But most often it is only a fleeting contact, for in the human being love is immediately mixed with lower egoistic movements which debase it and rob it of its power of purity. But even if it remained pure, this contact with the divine existence could not last for ever, for love is only one aspect of the Divine, an aspect which here on earth has suffered the same distortions as the others.
Besides, all these experiences are very good and useful for the ordinary man who follows the normal way of Nature in her stumbling march towards the future unity. But they cannot satisfy those who want to hasten the movement, or rather, who aspire to belong to another line of more direct and rapid movement, to an exceptional movement that will liberate them from ordinary mankind and its interminable march, so that they may take part in the spiritual advance which will lead them along the swiftest paths towards the creation of the new race, the race that will express the supramental truth upon earth. These rare souls must reject all forms of love between human beings, for how ever beautiful and pure they may be, they cause a kind of short circuit and cut off the direct connection with the Divine.
For one who has known love for the Divine, all other forms of love are obscure and too mixed with pettiness and egoism and darkness; they are like a perpetual haggling or a struggle for supremacy and domination, and even among the best they are full of misunderstanding and irritability, of friction and incomprehension.
Moreover, it is a well-known fact that one grows into the likeness of what one loves. Therefore if you want to be like the Divine, love Him alone. Only one who has known the ecstasy of the exchange of love with the Divine can know how insipid and dull and feeble any other exchange is in comparison. And even if the most austere discipline is required to arrive at this exchange, nothing is too hard, too long or too severe in order to achieve it, for it surpasses all expression.
This is the marvellous state we want to realise on earth; it is this which will have the power to transform the world and make it a habitation worthy of the Divine Presence. Then will pure and true love be able to incarnate in a body that will no longer be a disguise and a veil for it. Many a time, in order to make the discipline easier and to create a closer and more easily perceptible intimacy, the Divine has sought, in his highest form of love, to assume a physical body similar in appearance to the human body; but each time, imprisoned within the gross forms of Matter, he was able to express only a caricature of himself. And in order to manifest in the fullness of his perfection he waits only for human beings to have made some indispensable progress in their consciousness and in their bodies; for the vulgarity of man's vanity and the stupidity of his conceit mistake the sublime divine love, when it expresses itself in a human form, for a sign of weakness and dependence and need.
And yet man already knows, at first obscurely, but more and more clearly as he draws nearer to perfection, that love alone can put an end to the suffering of the world; only the ineffable joy of love in its essence can sweep away from the universe the burning pain of separation. For only in the ecstasy of the supreme union will creation discover its purpose and its fulfillment.
That is why no effort is too arduous, no austerity too rigorous if it can illumine, purify, perfect and transform the physical substance so that it may no longer conceal the Divine when he takes on an outer form in Matter. For then this marvellous tenderness will be able to express itself freely in the world, the divine love which has the power of changing life into a paradise of sweet joy.
This, you will say, is the culmination, the crown of the effort, the final victory; but what must be done in order to achieve it? What is the path to be followed and what are the first steps on the way?
Since we have decided to reserve love in all its splendour for our personal relationship with the Divine, we shall replace it in our relations with others by a total, unvarying, constant and egoless kindness and goodwill that will not expect any reward or gratitude or even any recognition. However others may treat you, you will never allow yourself to be carried away by any resentment; and in your unmixed love for the Divine, you will leave him sole judge as to how he is to protect you and defend you against the misunderstanding and bad will of others.
You will await your joys and pleasures from the Divine alone. In him alone will you seek and find help and support. He will comfort you in all your sorrows, guide you on the path, lift you up if you stumble, and if there are moments of failure and exhaustion, he will take you up in his strong arms of love and enfold you in his soothing sweetness.
To avoid any misunderstanding, I must point out here that because of the exigencies of the language in which I am expressing myself, I am obliged to use the masculine gender whenever I mention the Divine. But in fact the reality of love I speak of is above and beyond all gender, masculine or feminine; and when it incarnates in a human body, it does so indifferently in the body of a man or a woman according to the needs of the work to be done.
In summary, austerity in feelings consists then of giving up all emotional attachment, of whatever nature, whether for a person, for the family, for the country or anything else, in order to concentrate on an exclusive attachment for the Divine Reality. This concentration will culminate in an integral identification and will be instrumental to the supramental realisation upon earth.
This leads us quite naturally to the four liberations which will be the concrete forms of this achievement. The liberation of the feelings will be at the same time the liberation from suffering, in a total realisation of the supramental oneness.
The mental liberation or liberation from ignorance will establish in the being the mind of light or gnostic consciousness, whose expression will have the creative power of the Word.
The vital liberation or liberation from desire gives the individual will the power to identify itself perfectly and consciously with the divine will and brings constant peace and serenity as well as the power which results from them.
Finally, crowning all the others, comes the physical liberation or liberation from the law of material cause and effect. By a total self-mastery, one is no longer a slave of Nature's laws which make men act according to subconscious or semi-conscious impulses and maintain them in the rut of ordinary life. With this liberation one can decide in full knowledge the path to be taken, choose the action to be accomplished and free oneself from all blind determinism, so that nothing is allowed to intervene in the course of one's life but the highest will, the truest knowledge, the supramental consciousness.
