Sanskrit Concept-Root Atlas

Executive summary

The Bhagavad Gita does not merely use Sanskrit; it thinks in Sanskrit. Its key terms carry compressed philosophical, psychological, and yogic force that no single translation can fully render. Dharma holds and sustains. Karma does and binds. Yoga joins and integrates. Buddhi awakens and decides. Yajna offers and transforms. Tyaga releases. Moksha frees. Each root-word is a small teaching that opens into the large one.

This matters because the Gita’s argument is not static. The terms do not sit in a glossary at a fixed definition; they develop as the dialogue moves. Dharma begins as the field of crisis, narrows to Arjuna’s personal law, and finally yields to the Divine. Karma starts as obligation, becomes recognisable as bondage, and is then re-founded as sacrifice. Yoga widens from equality-of-mind to the union of the whole being with Krishna. Following the term is following the doctrine.

Sri Aurobindo’s reading makes the morphological heritage of these words a doorway, not a destination. The root-sense opens a conceptual gate; the Gita’s use of the word in its verses constitutes the teaching that passes through that gate. The atlas below traces fourteen such terms — from dharma at the opening field of battle to smriti at the closing recovery of memory — as a continuous movement of the soul toward liberation and surrender.

Key takeaways

• Each key Sanskrit term encodes a direction of movement, not merely a static category.
• The terms develop across the Gita’s chapters — tracking that development is itself a reading of the teaching.
• Root-sense opens the conceptual gate; the Gita’s verses constitute the doctrine that walks through it.
• The final sequence — saranam, moksha, smriti — is relational, not merely philosophical: it ends in surrender, release, and recovered memory.
• Inner renunciation (tyaga) is consistently privileged over outer abandonment (sannyasa); the Gita chooses transformed action over quietism.
• The gunas, prakriti, and purusha supply the diagnostic grammar of Nature, making it possible to see clearly and act freely.

Words That Move

The Gita’s Sanskrit terms are not decorative vocabulary appended to a teaching that could as well be stated in any language. They are concept-engines, and their root-senses are part of the argument.

Translation gives meaning, but root-sense gives movement. When Krishna uses the word dharma, he is drawing on a term whose root means to hold and sustain — and that holding function is precisely what is at stake through the whole first chapter and the crisis that opens the second. When he uses yoga, he draws on a root meaning to yoke and join — and that joining is the very act the teaching is trying to accomplish in Arjuna’s divided being. The words are doing philosophical work that parallels and reinforces the verse content.

What follows is an atlas of fourteen such terms, arranged in the order in which they become central to the Gita’s unfolding argument. For each, the root-sense is given first, then the doctrinal movement the term enacts across the text. Taken together, they form a second itinerary of the teaching — one that runs in parallel with the pedagogical sequence of chapters and discloses the same arc: from crisis to foundation, from foundation to action, from action to sacrifice, from sacrifice to surrender.

Sri Aurobindo’s insistence throughout the Essays on the Gita is that these words must not be flattened into their lowest or most habitual sense. Karma is not just ‘the law of cause and effect’ in a popular metaphysical sense; yoga is not merely a system of postures; dharma is not reducible to duty in an exclusively social register. Each term carries the whole weight of the Gita’s integral vision.

The method

A term is a compressed teaching.

1. Why Sanskrit Terms Matter

Language is not neutral to doctrine. When the Gita uses a word like buddhi, it summons not only a meaning but a history of philosophical use, a cluster of related terms, and a sense of the kind of activity being described. Translation necessarily narrows this field. The English word ‘intellect’ does not carry buddhi’s root sense of awakening; ‘reason’ carries none of the moral-discriminative force that buddhi exercises in the Gita’s ethical and yogic arguments.

The same holds for every key term. Dharma rendered simply as ‘duty’ loses the ontological weight of the holding-and-sustaining function that gives the word its philosophical depth. Karma rendered as ‘fate’ or ‘the fruits of past actions’ loses the radical insistence of the Gita that karma is primarily the present activity of action itself — and that this activity can be transformed at its root, not merely managed at its surface.

Sri Aurobindo’s translations in the Essays on the Gita are consistently alert to this problem. He keeps the Sanskrit terms in play even when giving English equivalents, precisely because the morphological field of the original word is carrying part of the argument. What looks like a translation choice is often a doctrinal decision.

The terms also develop within the Gita. To read dharma at 1·1 and then again at 18·66 is to trace a movement: from the field of conflict where dharma is a battleground, through Arjuna’s own svadharma as the specific law of his nature, to the final instruction to abandon all dharmas and take refuge in Krishna alone. The word has not changed its meaning, but its meaning has deepened and then exceeded itself.

Language and doctrine

Translation gives meaning, but root-sense gives movement.

2. Dharma: The Law That Holds

The root dhri — to hold, to sustain — establishes dharma as the foundational law that supports both being and right action. The field of Kurukshetra is called the dharmakshetra, the field of dharma, from the Gita’s very first verse 1·1: the setting is already defined by this term, already charged with the question of what law holds and what it means for it to fail.

Arjuna’s crisis in the first chapter is precisely a crisis of dharma: the law of the warrior, the law of the family, the law of the righteous man all appear to contradict one another. He cannot find the single holding principle that would tell him what to do. He appeals to Krishna as one who cannot see clearly 2·7: ‘My being is afflicted with the weakness of pity; my mind confused about dharma.’ The disciple is born at the moment when the ordinary dharma-structures have collapsed and the deeper law has not yet been disclosed.

As the teaching unfolds, dharma differentiates. There is the universal moral law, the caste-function, the natural law of one’s own being (svadharma), and ultimately the supreme law of surrender. At 3·35 Krishna states that one’s own svadharma, however imperfect, is better than another’s well-performed dharma — a statement not of social conservatism but of the principle that action must arise from the soul’s actual nature rather than from imitation of another’s path.

The arc ends at 18·66, where Krishna asks Arjuna to abandon all dharmas and take refuge in him alone. Dharma holds until the Divine becomes the holder. The term has not been negated; it has been fulfilled and transcended.

The arc of dharma

Dharma holds until the Divine becomes the holder.

3. Karma: Action As Doing And Becoming Bound

The root kri — to do, to make — establishes karma as action in the most fundamental sense: what is done, and what accrues to the doer. The Gita’s radical intervention is to show that the bondage is not in the action itself but in the relationship of the ego to the action. Action performed with desire for its fruits binds; action performed as yajna, as offering, does not.

The famous verse 2·47 establishes the principle: the right to action is yours, but never the fruits of that action. This is not indifference to outcome but the removal of the ego-claim that makes outcome the measure and motive of action. When outcome ceases to be the aim, action is freed from the cycle by which every doing generates more compelled doing.

Yet action cannot simply be abandoned. 3·5 makes the point explicit: no one can remain even for a moment without action; Nature herself compels it. The apparent escape of inaction is therefore an illusion. What is needed is the transformation of action’s basis, not its cessation. 3·9 names that transformation: work done as sacrifice, as yajna, is free from the chain of bondage.

At 4·18 Krishna introduces one of the most concentrated formulations: one who sees inaction in action and action in inaction is wise among men. The one who has truly transformed the basis of action leaves no karma-trace — not because action stops, but because ego-ownership of action ceases. The final instruction at 18·57 — surrender all actions to Krishna — is the completion of this movement.

The movement of karma

The Gita does not abolish karma; it transforms its basis.

4. Yoga: The Joining Power

The root yuj — to join, to yoke — reveals yoga as a principle of integration rather than a set of techniques. To practise yoga in the Gita’s sense is to bring the divided and scattered parts of one’s being into a single directed orientation. The many forms of yoga named in the Gita — buddhiyoga, karmayoga, jnanayoga, bhaktiyoga — are not competing paths but different facets of this one movement of integration.

2·48 gives the foundational definition: ‘Be steadfast in yoga, O Arjuna; perform action abiding in yoga, abandoning attachment, being equal in success and failure — samatvam yoga uchyate: equanimity is called yoga.’ Yoga is first of all this condition of inner equality, the poise from which action can proceed without being disturbed or deflected by result.

2·50 extends this to the field of works: the yoga-practitioner abandons both good and evil actions here in this life. This is not moral indifference but the transcendence of the ego-driven pair of seeking good results and avoiding bad ones — the condition that makes truly free and God-directed action possible. At 6·20–23 the vision of yoga deepens into the still, collected state of consciousness in which the mind rests in the Self and knows the infinite joy that transcends the senses.

Throughout the Essays on the Gita, Sri Aurobindo insists that the Gita’s yoga is integral — it does not require the abandonment of action or the world. The goal is not a retreat from engagement but a transformation of the one who engages. At 18·57 the final movement is named: yoga of consciousness means surrendering all actions to Krishna and making him the goal of the intellect.

The joining

Yoga is not technique alone; it is the right poise of the whole being.

5. Buddhi: The Awakened Intelligence

The root budh — to awaken — establishes buddhi as the intelligence that discerns and decides by virtue of being awake to reality. It is not reason in the merely logical sense but the highest cognitive-discriminative faculty of the human being: the power that sees through appearances, distinguishes the real from the unreal, and makes the decisive choices of life.

At 2·39–41 Krishna sets the buddhi of sankhya — clear metaphysical knowledge — beside the buddhi of yoga — the disciplined orientation of intelligence toward action and the divine. The buddhi that yoga requires is not many-branching and uncertain; it is vyavasayatmika, resolute and unified. The person of many-branching intelligence — constantly revisiting, constantly qualifying, never arriving at a settled orientation — cannot act freely.

The movement of buddhi through the Gita is from confusion to discernment, and then from discernment to surrender. At 18·57 the fully developed buddhi does not merely analyse and conclude; it resorts to Krishna, makes Krishna its final refuge. The intelligence that has awakened fully no longer claims to be the ultimate judge of reality; it offers its discernment back to the source of consciousness.

This arc matters for the Essays on the Gita because Sri Aurobindo consistently refuses to read the Gita’s yoga as anti-intellectual or as a bypassing of discrimination. The buddhi is not suppressed but fulfilled — raised to its highest function, which is ultimately the function of surrender to the greater Light.

Buddhi’s arc

The awakened intelligence is the bridge from confusion to surrender.

6. Atman: The Immortal Self

The word atman carries no derivative root-sense that needs explanation: it is the Self, the ultimate subject of experience, the ground of being that underlies and outlasts all personal formation. The Gita’s first use of atman-knowledge is therapeutic: Arjuna grieves for what cannot be destroyed. The great teaching of 2·11–25 removes the metaphysical ground of that grief by establishing that the Self is unborn, undying, indestructible, beyond sword and fire and water and wind.

But atman does not remain at the level of metaphysical consolation. As the teaching deepens, the knowledge of one’s own Self opens into the knowledge of the universal Self. At 6·29 the yogi who has achieved equality sees the Self in all beings and all beings in the Self — the narrow individual atman of the early chapters has expanded into the cosmic vision of atmanam sarvabhutesu.

This movement from the individual to the universal to the supreme is characteristic of the Gita’s integral approach. Self-knowledge first cures sorrow; then it widens perception; then it opens into the recognition of the Purushottama who stands beyond both individual and universal.

The widening of Atman

Self-knowledge first cures sorrow, then widens perception.

7. Yajna: Sacrifice As The Secret Of Works

Yajna — sacrifice, the act of offering — is the Gita’s key to the transformation of work. The root-sense of sacrificial offering reaches back to the Vedic fire-ritual in which something valued is placed into the fire for the gods; the Gita re-reads this ancient act as the universal principle by which action is diverted from ego-possession to divine consecration.

At 3·9 Krishna establishes that action in the world other than sacrifice is bondage. This is not a retreat into ritualism but a radical re-evaluation of what action essentially is. Every act performed with the ego’s claim upon its fruit binds the doer; every act performed as offering to the Divine frees the doer. The fire of yajna burns the binding element — the attachment — while releasing the energy of the action into its cosmic purpose.

4·23–33 extends the principle: all action is yajna for one who has seen rightly. The sacrifice of knowledge, which burns the karma-material entirely, is the highest of all sacrifices. The practitioner who understands this no longer performs external rituals as such but transforms every moment of engaged action into an act of consecration.

At 9·27 Krishna states the supreme form of this principle directly: whatever you do, whatever you eat, whatever you offer, whatever austerity you perform — do that as an offering to me. The boundary between sacred act and ordinary life dissolves; all activity becomes the substance of the sacrifice.

The work of yajna

Sacrifice is the spiritualisation of activity.

8. Tyaga And Sannyasa

The opening of Chapter 18 records Arjuna asking for a clear distinction between sannyasa — renunciation in the sense of abandoning works — and tyaga — renunciation in the sense of relinquishing the fruits of works. This is not a minor terminological query; it goes to the heart of the Gita’s practical teaching. Can one simply lay down action? Or is the laying-down something that must happen inwardly while action continues outwardly?

The root of tyaga — tyaj, to abandon — emphasises the act of letting go, of releasing one’s hold on something. The root of sannyasa — sam + ni + as, to lay down, to put aside completely — emphasises the external gesture of complete withdrawal. The Gita consistently privileges tyaga over sannyasa as a spiritual principle. At 5·1–6 Krishna points out that both paths lead to the highest good, but the way of works combined with inner renunciation is easier to travel and no less complete.

At 18·1–12 the distinction is sharpened further. The relinquishment of obligatory works is not approved; yajna, dana (giving), and tapas (austerity) are to be performed, not abandoned, even by one who seeks liberation. But the fruits of these works are to be released entirely. The tyagi — the one who has truly relinquished — performs action with a mind freed from clinging to outcome.

Sri Aurobindo reads this as the Gita’s decisive rejection of the quietist reading of spiritual life. The inner movement is what matters; outer abandonment without inner freedom is no freedom at all. Outer action with inner freedom is the Gita’s characteristic synthesis.

Tyaga and Sannyasa

The Gita chooses inward release over external quietism.

9. Guna: The Strands Of Nature

The word guna means a strand or quality, with the sense of a thread twisted into a cord. The three gunas — sattva (clarity, light, harmony), rajas (energy, passion, restlessness), and tamas (inertia, obscurity, heaviness) — are the operational strands of prakriti, Nature’s formative power. Everything in the natural world and in the human being is composed of these three in varying proportions.

3·27 makes the diagnostic use plain: all actions are performed by the gunas of Nature. The person who is deluded by the ego-sense thinks ‘I am the doer’; but the gunas are doing. This is not a counsel of passivity but an invitation to see through the ego’s ownership-claim. Once the gunas are seen clearly, the one who sees is no longer entirely governed by them.

14·5 names the binding function: sattva, rajas, and tamas — born of Nature — bind the incarnate soul in the body. Even sattva binds, with its attachment to knowledge and happiness. The Gita’s aim is not to maximise sattva but to transcend the gunas altogether — to reach the trigunatita, the state beyond all three strands.

The detailed mapping of gunas across 17·1–28 and 18·19–40 extends this diagnostic language to faith, food, sacrifice, charity, austerity, knowledge, action, doer, understanding, will, and happiness — every register of human activity is analysed by its guna-composition. The effect is to give the practitioner a complete discriminative vocabulary for understanding the quality of their own actions and inner states.

Guna analysis

The gunas are the diagnostic language of the lower nature.

10. Prakriti And Purusha

Prakriti — Nature, the formative and executive power of manifestation — and Purusha — the conscious being, the soul, the witness — are the two poles of the classical Sankhya metaphysics that underlies much of the Gita’s psychological analysis. Prakriti works; Purusha witnesses. Together they constitute the field of experience.

The Gita’s treatment of this pair at 7·4–5 introduces a distinction not present in orthodox Sankhya: the lower prakriti of the eight-fold material Nature (earth, water, fire, air, ether, mind, buddhi, ahankara) and the higher prakriti of the conscious self, the jiva who sustains the world. This is already a move beyond the Sankhya dyad, hinting at the synthesis that will come.

13·2–3 deepens this: the field (kshetra) and the knower of the field (kshetrajna) correspond to prakriti and Purusha, but Krishna identifies himself as the kshetrajna in all fields — the supreme Witness present in every creature, not a passive observer but the ground of all knowing.

15·16–18 completes the movement with the doctrine of the Purushottama. There are two Purushas in the world — the perishable, who is all these creatures, and the imperishable, who stands above — but there is a third, the highest Person, the Purushottama, who pervades and sustains all. The Sankhya distinction between prakriti and Purusha is not abolished but exceeded. Soul and Nature are distinguished so that they can be divinely reconciled in the supreme Person who is the source and master of both.

Prakriti and Purusha

Soul and Nature are distinguished so they can be divinely reconciled.

11. Svabhava And Svadharma

Svabhava — literally ‘own becoming’ or ‘own nature’ — and svadharma — the sustaining law proper to that nature — are among the most practically charged terms in the Gita. Together they answer the question of what action actually belongs to a given person: not what social category demands, not what another’s ideal prescribes, but what the soul’s own deepest nature requires.

The crisis of 2·7 is partly a svabhava-crisis: Arjuna’s warrior nature is obscured by grief and by a moral argument built from the outside. He has temporarily lost contact with the law of his own being. Krishna’s whole pedagogical effort can be read as restoring Arjuna to his svabhava — the warrior-kshatriya self whose proper action is action on the field of dharma, not withdrawal from it.

3·35 gives the principle explicitly: better one’s own svadharma, even if performed imperfectly, than the svadharma of another performed well. This is not social conservatism but a statement about the integrity of action: action that arises from the soul’s genuine nature, however flawed in execution, has a quality that borrowed action, however skillful, cannot possess.

By 18·45–48 the principle is applied to the four varnas — each person attains perfection by worshipping through their own work the one from whom all beings originate. The social form of svadharma is thereby grounded in a deeper spiritual principle. And at 18·59–60 the argument comes home to Arjuna directly: even if he refuses, his own nature will compel him. What appears as choice is already determined by svabhava. True action grows from the soul’s law, and then is offered beyond itself.

Svabhava and Svadharma

True action grows from the soul’s law, then is offered beyond itself.

12. Saranam: Refuge

The word saranam — refuge — appears near the end of the Gita and marks a decisive shift in the register of its teaching. The earlier terms — dharma, karma, yoga, buddhi — all name something the practitioner does or develops or knows. Saranam names a relationship into which the practitioner enters: the relation of taking shelter, of relying on another as one’s ultimate support.

18·62 prepares the ground: ‘Go to him for refuge with all your being, O Arjuna; by his grace you will attain supreme peace and the eternal resting-place.’ The movement here is not of intellectual achievement or even of spiritual effort in the ordinary sense, but of the whole being turning toward and resting in the Divine.

18·66 makes saranam the culminating term of the Gita’s entire argument. Abandon all dharmas; come to me alone for refuge. I will release you from all sin and evil; do not grieve. The word ‘dharmas’ here includes all the frameworks of obligation, rule, and law that the Gita has been building for seventeen chapters. All of them are now exceeded — not negated, but transcended — in the act of total refuge.

Sri Aurobindo reads this not as an abrupt reversal of everything that came before but as its natural culmination. The disciplines of yoga, the clarity of buddhi, the transformation of karma into yajna, the refinement of tyaga — all of these were preparing the ground for this relational act. The final Sanskrit concept is not abstract; it is the posture of the soul before the Divine.

Saranam

The final Sanskrit concept is relational, not abstract.

13. Moksha: Release

The root muc — to release, to let go — establishes moksha as the condition of one who has been freed. It is not something the soul achieves alone, as if liberation were a peak climbed by individual effort; the Gita’s formulation at 18·66 makes it explicit that Krishna will release Arjuna from all sin and evil. Release comes by surrender to the Divine as much as — or more than — by the soul’s own attainment.

This framing of moksha is characteristic of the Gita’s theism. The liberation of the soul is not an impersonal logical consequence of metaphysical knowledge, as in some readings of Advaita; it is the act of the Divine Presence moving in the soul that has opened itself to receive it. Moksha is the Divine’s act as much as the soul’s attainment.

At the same time, the Gita does not wait for moksha to become practically relevant only at the end of the teaching. The whole arc of karma transformed into yajna, of buddhi unified and then surrendered, of the gunas transcended — this is the movement toward moksha already in progress throughout every chapter. Liberation is not a future state but a present direction of movement.

Release

Moksha is the Divine’s act as much as the soul’s attainment.

14. Smriti: The Return Of Memory

The final term is smriti — memory, the root smri meaning to remember or to recollect. At 18·73, the Gita’s closing exchange, Arjuna says: ‘nasto moha smritir labdha — my delusion is gone; I have regained my memory.’ This is the teaching’s last word from the disciple, and it is charged with significance.

Arjuna does not say ‘I have received new information’ or ‘I have mastered a new system.’ He says he has remembered. What the teaching has restored is not something external that was previously absent but something internal that was obscured. The soul’s knowledge of itself and of the Divine — its true orientation, its right relationship to action and to the Supreme — was always there. The Gita’s entire movement has been the removal of what obscured it.

Smriti as the endpoint of the teaching establishes the Gita’s characteristic epistemology: liberation is not the acquisition of something new but the recovery of what the soul already is. The whole pedagogical sequence — from rebuke to self-knowledge to sacrifice to surrender — was a long act of remembering. And now that memory is restored, Arjuna can act.

Smriti

The end of the Gita is not new information, but recovered soul-knowledge.

In Sum

The Gita’s Sanskrit is alive with movement. These fourteen terms — from dharma at the opening field to smriti at the close — are not a glossary appended to a teaching that could be stated without them. They are the teaching’s inner skeleton. Their root-senses enact the doctrines they carry: dharma holds until what holds it is exceeded; karma does and binds until it is freed into offering; yoga joins until what is joined becomes complete; buddhi awakens until it is given back to the Light; yajna sacrifices until all of life is sacrifice; tyaga releases; moksha frees; smriti recovers.

To trace these words across the Gita’s chapters is therefore to trace a second itinerary of the teaching alongside the pedagogical sequence. Both itineraries arrive at the same place: the soul that has been instructed, purified, and freed enough to take full refuge in the Divine and to act from that refuge without grief or bondage.

Sri Aurobindo’s consistent insistence in the Essays on the Gita is that this movement is integral: it does not arrive at liberation by subtracting action or world or self, but by transforming the basis and orientation of all three. The Sanskrit terms are the carriers of that integral claim. To understand them in their morphological depth and their doctrinal development is to understand why the Gita is not merely a scriptural teaching but, as Sri Aurobindo puts it, a scripture of spiritual life and action — alive in every word.

To follow the development of these Sanskrit terms is to follow the teaching itself — from the crisis of dharma at Kurukshetra to the recovery of memory and free action at the teaching’s close.
