First there comes a description of cosmic existence in the Vedantic image of the aswattha tree. This tree of cosmic existence has no beginning and no end, nanto na chadih, in space or in time; for it is eternal and imperishable, avyaya. The real form of it cannot be perceived by us in this material world of man’s embodiment, nor has it any apparent lasting foundation here; it is an infinite movement and its foundation is above in the supreme of the Infinite. Its principle is the ancient sempiternal urge to action, pravritti, which for ever proceeds without beginning or end fromthe original Soul of all existence, adyam purusham… yatah pravrittih prasrita puranı. Therefore its original source is above, beyond Time in the Eternal, but its branches stretch down below and it extends and plunges its other roots, well-fixed and clinging roots of attachment and desire with their consequences of more and more desire and an endlessly developing action, plunges them downward here into the world of men. The hymns of the Veda are compared to its leaves and the man who knows this tree of the cosmos is the Veda-knower. And here we see the sense of that rather disparaging view of the Veda or at least of the Vedavada, which we had to notice at the beginning. For the knowledge the Veda gives us is a knowledge of the gods, of the principles and powers of the cosmos, and its fruits are the fruits of a sacrifice which is offered with desire, fruits of enjoyment and lordship in the nature of the three worlds, in earth and heaven and the world between earth and heaven. The branches of this cosmic tree extend both below and above, below in the material, above in the supraphysical planes; they grow by the gunas of Nature, for the triple guna is all the subject of the Vedas, traigunyavishaya vedah. The Vedic rhythms, chandamsi, are the leaves and the sensible objects of desire supremely gained by a right doing of sacrifice are the constant budding of the foliage. Man, therefore, so long as he enjoys the play of the gunas and is attached to desire, is held in the coils of Pravritti, in the movement of birth and action, turns about constantly between the earth and the middle planes and the heavens and is unable to get back to his supreme spiritual infinitudes. This was perceived by the sages. To achieve liberation they followed the path of Nivritti or cessation from the original urge to action, and the consummation of this way is the cessation of birth itself and a transcendent status in the highest supracosmic reach of the Eternal. But for this purpose it is necessary to cut these longfixed roots of desire by the strong sword of detachment and then to seek for that highest goal whence, once having reached it, there is no compulsion of return to mortal life. To be free from the bewilderment of this lower Maya, without egoism, the great fault of attachment conquered, all desires stilled, the duality of joy and grief cast away, always to be fixed in wide equality, always to be firm in a pure spiritual consciousness, these are the steps of the way to that supreme Infinite. There we find the timeless being which is not illumined by sun or moon or fire, but is itself the light of the presence of the eternal Purusha. I turn away, says the Vedantic verse, to seek that original Soul alone and to reach him in the great passage. That is the highest status of the Purushottama, his supracosmic existence.
But it would seem that this can be attained very well, best even, pre-eminently, directly, by the quiescence of Sannyasa. Its appointed path would seem to be the way of the Akshara, a complete renunciation of works and life, an ascetic seclusion, an ascetic inaction. Where is the room here, or at least where is the call, the necessity, for the command to action, and what has all this to do with the maintenance of the cosmic existence, lokasangraha, the slaughter of Kurukshetra, the ways of the Spirit in Time, the vision of the million-bodied Lord and his highvoiced bidding, “Arise, slay the foe, enjoy a wealthy kingdom”? And what then is this soul in Nature? This spirit too, this Kshara, this enjoyer of our mutable existence, is the Purushottama; it is he in his eternal multiplicity, that is the Gita’s answer. “It is an eternal portion of me that becomes the Jiva in a world of Jivas.” This is an epithet, a statement of immense bearing and consequence. For it means that each soul, each being in its spiritual reality is the very Divine, however partial its actual manifestation of him in Nature. And it means too, if words have any sense, that each manifesting spirit, each of the many, is an eternal individual, an eternal unborn and undying power of the one Existence. We call this manifesting spirit the Jiva, because it appears here as if a living creature in a world of living creatures, and we speak of this spirit in man as the human soul and think of it in the terms of humanity only. But in truth it is something greater than its present appearance and not bound to its humanity: it was a lesser manifestation than the human in its past, it can become something much greater than mental man in its future. And when this soul rises above all ignorant limitation, then it puts on its divine nature of which its humanity is only a temporary veil, a thing of partial and incomplete significance. The individual spirit exists and ever existed beyond in the Eternal, for it is itself everlasting, sanatana. It is evidently this idea of the eternal individual which leads the Gita to avoid any expression at all suggestive of a complete dissolution, laya, and to speak rather of the highest state of the soul as a dwelling in the Purushottama, nivasishyasi mayyeva. If when speaking of the one Self of all it seems to use the language of Adwaita, yet this enduring truth of the eternal individual, mamanshah sanatanah, adds something which brings in a qualification and appears almost to accept the seeing of the Visishtadwaita,— though we must not therefore leap at once to the conclusion that that alone is the Gita’s philosophy or that its doctrine is identical with the later doctrine of Ramanuja. Still this much is clear that there is an eternal, a real and not only an illusive principle of multiplicity in the spiritual being of the one divine Existence.
This eternal individual is not other than or in any way really separate from the Divine Purusha. It is the Lord himself, the Ishwara who by virtue of the eternal multiplicity of his oneness —is not all existence a rendering of that truth of the Infinite?— exists for ever as the immortal soul within us and has taken up this body and goes forth from the transient framework when it is cast away to disappear into the elements of Nature. He brings in with him and cultivates for the enjoyment of the objects of mind and sense the subjective powers of Prakriti, mind and the five senses, and in his going forth too he goes taking them as the wind takes the perfumes from a vase. But the identity of the Lord and the soul in mutable Nature is hidden from us by outward appearance and lost in the crowding mobile deceptions of that Nature. And those who allow themselves to be governed by the figures of Nature, the figure of humanity or any other form, will never see it, but will ignore and despise the Divine lodged in the human body. Their ignorance cannot perceive him in his coming in and his going forth or in his staying and enjoying and assumption of quality, but sees only what is there visible to the mind and senses, not the greater truth which can only be glimpsed by the eye of knowledge. Never can they have sight of him, even if they strive to do so, until they learn to put away the limitations of the outward consciousness and build in themselves their spiritual being, create for it, as it were, a form in their nature. Man, to know himself, must be kritatma, formed and complete in the spiritual mould, enlightened in the spiritual vision. The Yogins who have this eye of knowledge, see the Divine Being we are in their own endless reality, their own eternity of spirit. Illumined, they see the Lord in themselves and are delivered from the crude material limitation, from the form of mental personality, from the transient life formulation: they dwell immortal in the truth of the self and spirit. But they see him too not only in themselves, but in all the cosmos. In the light of the sun that illumines all this world they witness the light of the Godhead which is in us; the light in the moon and in fire is the light of the Divine. It is the Divine who has entered into this form of earth and is the spirit of its material force and sustains by his might these multitudes. The Divine is the godhead of Soma who by the rasa, the sap in the Earth-mother, nourishes the plants and trees that clothe her surface. The Divine and no other is the flame of life that sustains the physical body of living creatures and turns its food into sustenance of their vital force. He is lodged in the heart of every breathing thing; from him are memory and knowledge and the debates of the reason. He is that which is known by all the Vedas and by all forms of knowing; he is the knower of Veda and the maker of Vedanta. In other words, the Divine is at once the Soul of matter and the Soul of life and the Soul of mind as well as the Soul of the supramental light that is beyond mind and its limited reasoning intelligence.
Thus the Divine is manifest in a double soul of his mystery, a twofold power, dvavimau purushau; he supports at once the spirit of mutable things that is all these existences, ksharah sarvani bhutani, and the immutable spirit that stands above them in his imperturbable immobility of eternal silence and calm. And it is by the force of the Divine in them that the mind and heart and will of man are so powerfully drawn in different directions by these two spirits as if by opposing and incompatible attractions one insistent to annul the other. But the Divine is neither wholly the Kshara, nor wholly the Akshara. He is greater than the immutable Self and he is much greater than the Soul of mutable things. If he is capable of being both at once, it is because he is other than they, anyah, the Purushottama above all cosmos and yet extended in the world and extended in the Veda, in self-knowledge and in cosmic experience. And whoever thus knows and sees him as the Purushottama, is no longer bewildered whether by the world-appearance or by the separate attraction of these two apparent contraries. These at first confront each other here in him as a positive of the cosmic action and as its negative in the Self who has no part in an action that belongs or seems to belong entirely to the ignorance of Nature. Or again they challenge his consciousness as a positive of pure, indeterminable, stable, eternal self-existence and as its negative of a world of elusive determinations and relations, ideas and forms, perpetual unstable becoming and the creating and uncreating tangle of action and evolution, birth and death, appearance and disappearance. He embraces and escapes them, overcomes their opposition and becomes allknowing, sarvavid, a whole-knower. He sees the entire sense both of the self and of things; he restores the integral reality of the Divine; he unites the Kshara and the Akshara in the Purushottama. He loves, worships, cleaves to and adores the supreme Self of his and all existence, the one Lord of his and all energies, the close and far-off Eternal in and beyond the world. And he does this too with no single side or portion of himself, exclusive spiritualised mind, blinding light of the heart intense but divorced from largeness, or sole aspiration of the will in works, but in all the perfectly illumined ways of his being and his becoming, his soul and his nature. Divine in the equality of his imperturbable self-existence, one in it with all objects and creatures, he brings that boundless equality, that deep oneness down into his mind and heart and life and body and founds on it in an indivisible integrality the trinity of divine love, divine works and divine knowledge. This is the Gita’s way of salvation.
And is that not too after all the real Adwaita which makes no least scission in the one eternal Existence? This utmost undividing Monism sees the one as the one even in the multiplicities of Nature, in all aspects, as much in the reality of self and of cosmos as in that greatest reality of the supracosmic which is the source of self and the truth of the cosmos and is not bound either by any affirmation of universal becoming or by any universal or absolute negation. That at least is the Adwaita of the Gita. This is the most secret Shastra, says the Teacher to Arjuna; this is the supreme teaching and science which leads us into the heart of the highest mystery of existence. Absolutely to know it, to seize it in knowledge and feeling and force and experience is to be perfected in the transformed understanding, divinely satisfied in heart and successful in the supreme sense and objective of all will and action and works. It is the way to be immortal, to rise towards the highest divine nature and to assume the eternal Dharma.
