BG-2.17 — The Imperishable, by Which All This Is Pervaded

BG-2.17

अविनाशि तु तद्विद्धि येन सर्वमिदं ततम् । विनाशमव्ययस्यास्य न कश्चित्कर्तुमर्हति ॥१७॥

"Know THAT to be indestructible by which all this is pervaded. No one is able to effect the destruction of this inexhaustible One."

This is the positive culmination of the Gītā's first great argument — the immortal-Self teaching (BG-2.11-30) by which Kṛṣṇa lifts Arjuna out of his battlefield collapse. Having said in BG-2.16 that the unreal has no being and the real never ceases to be, the verse here names that imperishable real: the Self that pervades everything, which no one is competent to destroy. Two negative epithets — avināśi (imperishable) and avyaya (inexhaustible) — flank one positive predicate — yena sarvam idam tatam (by which all-this is woven-through). Jñāneśvar answers the verse's central imperative — viddhi, KNOW! — with the method that obeys it: सारासार-विचार, the discrimination of essence from non-essence. Three ovis, no ornament: discriminate (2.133), see the pervasion (2.134), name the deathlessness (2.135).

Ovi 2.133

Original (Marathi): देखें सारासार विचारितां । भ्रांति ते पाहीं असारता । तरी सार तें स्वभावता । नित्य जाणें ॥१३३॥ Voice: krishna-to-arjuna (the imperative जाणें "KNOW" renders the Sanskrit विद्धि — Kṛṣṇa's epistemic command continuing the immortal-Self instruction of BG-2.11-30)

Word-by-word gloss

Marathi	Meaning
देखें	look / behold (attention-imperative)
सारासार विचारितां	when one discriminates essence from non-essence (sāra/asāra)
भ्रांति ते पाहीं असारता	delusion (bhrānti) — see — is the non-essence (asāratā)
तरी सार तें स्वभावता	then the essence (sāra), by its own nature (svabhāvatā)
नित्य जाणें	know it as eternal (nitya)

Literal translation

English: Look — when you discriminate the essence from the non-essence, delusion, see, is the non-essence; then the essence, by its very nature, know to be eternal.

मराठी (आधुनिक): बघ — सार आणि असार यांचा विचार केलास तर, भ्रम हाच असार आहे हे दिसेल; मग जे सार आहे ते स्वभावतःच नित्य आहे, असं जाण.

Sanskrit-root note

sāra-asāra-vicāra — sāra (pith, essence, what-remains) + a-sāra (pithless) + vicāra (discriminative inquiry); the same viveka-operation that Vedānta calls nitya-anitya-vastu-viveka, the discrimination of the eternal from the non-eternal, here named directly.

Metaphor-unfold

No extended metaphor in this ovi. सारासार-विचार is a doctrinal term of discrimination, not a sustained image.

Nāth-yogic layer

No Nāth-yogic referent in this ovi. This is Sānkhya/Vedānta viveka-discrimination, not cakra or kuṇḍalinī esotericism.

Cross-references

Internal: Brackets the cluster with 2.135 — the viveka here isolates exactly the imperishable-deathless essence that 2.135 names in full (सर्वगतु, जन्मक्षयातीतु).
Tukaram parallel: Abhang 20 — तुका म्हणे चित्तीं बैसला अनंत । दिसों नेदी नित्य अनित्य तें ("Tuka says: the Infinite has sat in the heart; it does not let the permanent and the impermanent be seen as separate"). The same नित्य/अनित्य axis this ovi turns on — but inverted in its resolution. Jñāneśvar uses the discrimination to isolate the imperishable (separate सार from असार); Tukaram reports its experiential dissolution once the Infinite is seated in the heart (the two no longer seen as separate). Same axis, opposite operation — viveka here, its non-dual completion there. (Line verified verbatim against corpus/0020.md.)
Source citation: Bhagavad Gītā 2.17 — विद्धि...अविनाशि ("KNOW...the imperishable"); the सारासार-विचार discrimination is Jñāneśvar's gloss on how the viddhi imperative is obeyed — knowing the imperishable requires separating the नित्य essence from the अनित्य delusion.

Modern application

When grief or panic has fused the changing thing with the whole of what you love. Someone is dying, a phase is ending, a body is failing — and the mind, undiscriminating, treats all of it as perishing. सारासार-विचार is the act of asking, inside the grief: what here is actually the असार (the part that was always going to change), and what is the सार (the part that never began and so cannot end)?
When your sense of self is welded to something destructible. A title, a role, a reputation, the body's appearance. The terror of losing it is the terror of losing yourself — because you have not yet performed the discrimination that shows the self is not the destructible layer.
When you must separate signal from noise under pressure. The manager flooded with information, the analyst drowning in data: सारासार-विचार is the same disciplined operation in a secular key — the deliberate sorting of the load-bearing essence from the delusion that mimics it.

Sādhanā

Today, take one specific fear of loss you are carrying. On a single line, write the perishable part (असार) and the imperishable part (सार) of what it concerns — for example, "the role will end (असार) / the capacity to begin again does not (सार)." Just one sorting. Notice which side the fear was secretly attached to.

Arc

2.133 supplies the method of knowing the imperishable (discriminate essence from delusion); 2.134 turns to what that essence is by its world-function — the three-worlds are only its expansion.

Ovi 2.134

Original (Marathi): हा लोकत्रयाकारु । तो जयाचा विस्तारु । तेथ नाम वर्ण आकारु । चिन्ह नाहीं ॥१३४॥ Voice: krishna-to-arjuna (continuing the immortal-Self exposition; the verse-element येन सर्वमिदं ततम् is being rendered)

Word-by-word gloss

Marathi	Meaning
हा लोकत्रयाकारु	this form of the three worlds (loka-traya-ākāra)
तो जयाचा विस्तारु	is the expansion / spreading-out (vistāra) of THAT
तेथ नाम वर्ण आकारु	there, name (nāma), colour (varṇa), form (ākāra)
चिन्ह नाहीं	(and) mark / sign (cihna) are not

Literal translation

English: This three-world form is the expansion of THAT; there, name, colour, form, and mark have no place.

मराठी (आधुनिक): हे त्रैलोक्याचं रूप म्हणजे त्या (परमतत्त्वा)चाच विस्तार आहे; पण त्या (मूळ तत्त्वा)त नाव, रंग, आकार, खूण असं काहीच नाही.

Sanskrit-root note

vistāra = vi (apart) + √stṛ (to spread); a near-cognate of the Gītā's own tatam (from √tan, to stretch) — Jñāneśvar renders the Sanskrit "pervaded / stretched-through" with the Marathi "expansion / spread-out," keeping the spreading-image exact.

Metaphor-unfold

No extended metaphor in this ovi. विस्तारु ("expansion") renders the Sanskrit ततम् ("stretched-through") as a single doctrinal verb of pervasion, not a sustained unfolding image.

Nāth-yogic layer

No Nāth-yogic referent in this ovi. लोकत्रय ("three worlds") is cosmological-Vedāntic, not a reference to yogic body-loci; the formlessness named here (नाम वर्ण आकारु चिन्ह नाहीं) is apophatic Self-description, not cakra-esotericism.

Source citations:
Bhagavad Gītā 2.17 — येन सर्वमिदं ततम् ("by which all this is pervaded"); रendered जयाचा विस्तारु ("whose expansion the three-worlds are"). The closing तेथ नाम वर्ण आकारु चिन्ह नाहीं is Jñāneśvar's apophatic amplification — the pervader is formless, the named-and-formed cosmos being only its expansion.
Bṛhadāraṇyaka Upaniṣad 4.4.22 (echo) — the महान् अज आत्मा, the great unborn Self who is sarveśvara / sarvasya vaśī, the lord-and-controller pervading all (sa vā eṣa mahānaja ātmā...). The pervading-Self-of-which-all-is-the-expansion resonates with that all-pervading immortal ātman. Kept at echo: Jñāneśvar names no source, and the Marathi renders the Gītā's ततम् directly.

Modern application

When you confuse the expression of a thing with the thing itself. A person's reputation, a company's brand, a tradition's outward forms — all of it नाम-वर्ण-आकार, name-colour-form — is the विस्तार, the spreading-out, not the source. Mistaking the spread for the source is how we grieve a brand-change as a death.
When you need to act on the formless behind the formful. The values behind the role, the intent behind the words, the love behind the gestures — the source that has "no name, colour, form, or mark" but of which all the visible particulars are the expansion. Leading or loving at the source rather than at the surface.
When the world's sheer multiplicity feels meaningless. The three-worlds, all of it, as one thing's expansion — not a random scatter of forms but the spreading-out of a single formless ground. A reframe for the vertigo of a too-large, too-various world.

Sādhanā

Today, pick one thing you tend to identify with its outer form — your job title, your home, a relationship's familiar rituals. For sixty seconds, ask: what is the formless thing of which this visible form is only the विस्तार, the expansion? Name the source under the form, once.

Arc

2.134 establishes the essence as the formless pervader whose expansion the cosmos is; 2.135 names it by its two great negative-epithets — all-pervading, beyond birth-and-decay — and seals the imperishability: even a slaying never befalls it.

Ovi 2.135

Original (Marathi): जो सर्वदा सर्वगतु । जन्मक्षयातीतु । तया केलियाहि घातु । कदा नोहे ॥१३५॥ Voice: krishna-to-arjuna (sealing the immortal-Self teaching; rendering अविनाशि + अव्यय + विनाशम्...न कश्चित्कर्तुमर्हति)

Word-by-word gloss

Marathi	Meaning
जो सर्वदा सर्वगतु	which is always (sarvadā) all-pervading (sarva-gata)
जन्मक्षयातीतु	beyond birth-and-decay (janma-kṣaya-atīta)
तया केलियाहि घातु	to it, even if a slaying / striking-down (ghāta) be done
कदा नोहे	it never (kadā) befalls / never comes to be

Literal translation

English: That which is forever all-pervading, beyond birth and decay — even if a slaying be aimed at it, destruction never befalls it.

मराठी (आधुनिक): जे नेहमी सर्वव्यापी आहे, जन्म आणि क्षय यांच्या पलीकडे आहे — त्याच्यावर घाव घातला तरी त्याचा नाश कधीच होत नाही.

Sanskrit-root note

janma-kṣaya-atīta = janma (birth) + kṣaya (waning, decay) + atīta (gone-beyond); this compound glosses the Gītā's avyaya ("without-diminution," a-vyaya, from vi-i "to wane") — both name the Self as that which never decreases.

Metaphor-unfold

No extended metaphor in this ovi. घातु ("a slaying / striking-down") is the literal Sanskrit vināśa (destruction) rendered concretely, not an unfolded image.

Nāth-yogic layer

No Nāth-yogic referent in this ovi. सर्वगतु (all-pervading) and जन्मक्षयातीतु (beyond birth-decay) are Vedāntic ātman-epithets; the deathless-Self formula here is Upaniṣadic, not Nātha-yogic.

Cross-references

Internal: Closes the viveka-bracket with 2.133 — the discrimination of 2.133 isolates exactly the imperishable-pervading-deathless essence that this ovi names in full.

Source citations:
Bhagavad Gītā 2.17 — अविनाशि + अव्यय and विनाशमव्ययस्यास्य न कश्चित्कर्तुमर्हति, रendered सर्वगतु / जन्मक्षयातीतु / केलियाहि घातु कदा नोहे. सर्वगतु glosses the pervasion, जन्मक्षयातीतु glosses अव्यय, केलियाहि घातु कदा नोहे glosses no-one is competent to destroy it.
Kaṭha Upaniṣad 1.2.18 (direct-paraphrase) — अजो नित्यः शाश्वतोऽयं पुराणो न हन्यते हन्यमाने शरीरे ("unborn, eternal, everlasting, ancient — it is not slain when the body is slain"). This ovi's जन्मक्षयातीतु...केलियाहि घातु कदा नोहे is a near-literal Marathi rendering of that deathless-Self formula, imported to gloss BG-2.17's अविनाशि/अव्यय.
Bhagavad Gītā 2.20 (paraphrase) — न जायते म्रियते वा...अजो नित्यः...न हन्यते हन्यमाने शरीरे recurs verbatim just three verses ahead; Jñāneśvar's केलियाहि घातु कदा नोहे already draws on this "not-slain-when-the-body-is-slain" claim while still commenting on 2.17. The avināśi of 2.17 and the na hanyate of 2.20 are one doctrine.

Modern application

When the fear of death (yours or another's) is at its rawest. This is the verse's literal first reading and its bhakti-core: the indweller is not what is struck down. The grief is real; the claim is that its deepest object — the Self — is precisely the thing a घात, a blow, cannot reach. केलियाहि घातु कदा नोहे: even the slaying does not land where it seems to.
When you over-identify with a destructible role or reputation under attack. A public takedown, a failure, a loss of standing can feel annihilating. The discrimination of this cluster says: something in you is सर्वगतु, all-pervading, जन्मक्षयातीतु, beyond what was born — and that something is untouched by the blow that fell on the role.
When you are tempted to act as if everything is at stake in one outcome. The verse re-scopes the stakes: the perishable layer is genuinely at risk; the imperishable is not — and clarity about which is which is exactly what frees decisive action (the ground BG-2.18's "therefore fight" will stand on).

Sādhanā

Today, in one quiet minute, locate one thing in you that you can honestly say was never born and cannot be struck — not a belief about it, but the bare witnessing-awareness reading these words right now. Rest attention on that for the length of three breaths. Note that the blows of the day fall on the role, not on the one noticing them.

Arc

2.135 seals the cluster on the deathless, all-pervading Self; the next śloka (BG-2.18) pivots from the indestructible indweller to the perishable bodies it wears — "these bodies of the eternal embodied-One are said to have an end" — turning the immortal-Self doctrine toward its practical conclusion: grieve neither for the imperishable (which cannot die) nor for the perishable (which was always going to).

Cluster summary

Core teaching: BG-2.17 names the imperishable Self as the object the Gītā commands Arjuna to know — indestructible, by which all-this-cosmos is pervaded, the inexhaustible One no one is competent to destroy. Jñāneśvar renders the verse in three surgical ovis: discriminate essence from delusion and the essence is by-nature eternal (2.133); the three-worlds are only its formless expansion, where name and form have no place (2.134); ever all-pervading and beyond birth-and-decay, even a slaying never befalls it (2.135). The whole cluster answers Arjuna's collapse: you grieve for what cannot perish.

Chapter arc position: This is the positive culmination of the immortal-Self teaching (BG-2.11-30) by which Kṛṣṇa first lifts Arjuna out of grief in adhyāya 2 (Sānkhya-yoga). Having distinguished real from unreal in BG-2.16, the Gītā here names the imperishable real, and Jñāneśvar supplies the सारासार-विचार discrimination that the verse's viddhi ("KNOW!") demands. The Vedāntic deathless-Self formula it imports (Kaṭha 1.2.18 / BG-2.20: न हन्यते हन्यमाने शरीरे) shows the cluster reaching forward to the same doctrine the chapter will restate three verses on.

Connects to BG-2.18: अन्तवन्त इमे देहा नित्यस्योक्ताः शरीरिणः — the Gītā turns from the imperishable indweller to the perishable bodies it wears: these bodies of the eternal embodied-One are said to have an end. Where BG-2.17 establishes what cannot be destroyed, BG-2.18 names what is bound to die anyway — and on this double ground (grieve neither for the deathless nor for the doomed) the explicit "therefore fight" of the immortal-Self argument will rest.
