Cluster 0226 — BG 6.15 — The Kundalini Ascent: Suṣumnā, Cakra-Piercing, and the Samarasa of Sky-into-Sky

Original (Sanskrit): युञ्जन्नेवं सदात्मानं योगी नियतमानसः । शान्ति निर्वाणपरमां मत्संस्थामधिगच्छति ॥१५॥

Constantly yoking the self thus, the yogī of restrained mind attains the peace — culminating in nirvāṇa — that abides in Me.

This single śloka is the culmination-verse of the first arc of chapter 6. The technical-yoga unfolding that opened with the prepared seat (BG-6.11-12) and proceeded through body-straightness and the brahmacarya-vrata (BG-6.13-14) here delivers its terminal fruit: the nirvāṇa-paramā śānti that is mat-samsthā — peace that abides in Kṛṣṇa himself. And on the authority of that one word, adhigacchati ("he attains"), Jñāneśvar opens the longest and most explicitly Nāth-tantric stretch in the entire Dnyāneśvarī. Where the Sanskrit says only "attains," the Marathi unfolds the how of the attainment as a step-by-step ascent of the kuṇḍalinī through the suṣumnā: the body becomes a sky-walker, the elements dissolve into one another, the rising power loses one name and takes another, she pierces the crown, embraces the formless Śiva, and even the last subtle sky is exhausted in the merger called samarasa. Then the commentator's own speech fails before what he has described, the verse turns through a sudden burst of devotional vision, and it closes with Arjuna's anxious question — am I even qualified for this? — and Kṛṣṇa's quietly radical answer.

The 52 ovis of this cluster (6.293 through 6.344) fall into a clear arc. First the ascent proper (6.293-6.310): khecara, the bhūta-laya cascade, the kuṇḍalinī-to-mārutī naming-shift, the cakra-piercing, the embrace in the brahmarandhra, and the sky-into-sky merger. Then the via-negativa stretch (6.311-6.322) where speech, thought, and even space recede. Then the bhakti pivot (6.323-6.327) that saves the whole from pure negation. And finally the closing dialogue (6.328-6.344) on the question of yogyatā — fitness for the path. What follows walks that arc thematically rather than ovi-by-ovi.

The body disappears: the khecara-state

ऐकें शक्तीचें तेज जेव्हां लोपे । तेथ देहाचें रूप हारपे । मग तो डोळ्यांमाजीं लपे । जगाचिया ॥२९३॥

The first experiential mark of constant yoking, as the Marathi reads it, is not a feeling but a disappearance. "Listen — when the radiance of the śakti withdraws (lōpe), there the body's form is lost (hārape); then he hides within the eye of the world (jagāchiyā ḍōḷyāmmājīm lapē)." The śakti here is unambiguously the kuṇḍalinī. When her tejas, her radiance, turns inward instead of animating the visible body, the rūpa — the seeable form — falls away. The world's eye can no longer find him, even though the world remains visible to him. This is the standard Nāth-haṭha description of the antardhāna-siddhi, the invisibility that accompanies advanced kuṇḍalinī-stabilization. BG-6.15's yuñjan evam sadā — "yoking thus constantly" — authorizes precisely this constancy under which the radiance turns inward; the Haṭha-yoga-pradīpikā's image of the awakened kuṇḍalī climbing upward supplies the frame, here described from the world's side: as she climbs, her light leaves the body and the body vanishes.

एऱ्हवीं आधिलाचि ऐसें । सावयव तरी दिसे । परी वायूचें कां जैसें । वळिलें होय ॥२९४॥ नातरी कर्दळीचा गाभा । बुंथी सांडोनी उभा । कां अवयवचि नभा । उदयला तो ॥२९५॥

The paradox is then sharpened. The form is still articulated as before — sāvayava tarī dise, it still appears limb-by-limb, the joint-structure is recognizable — "but as though rolled out of wind" (vāyūchēm vaḷilēm). The shape persists; the density is gone. Two further images render the same wind-body. First the banana-pith: kardaḷīchā gābhā buntī sāṇḍōnī ubhā — the soft inner pith of the banana-plant, which has no woody stem, standing upright once all its leaf-sheaths are stripped away. Essence without husk. Then a second image: avayava-chi nabhā udayalā — limb-articulation alone, risen up into the sky — a form that has joints without mass, articulation without weight. Both are precise Marathi renderings of the vāyu-deha, the wind-body that follows the dissolution of the lower elements as the kuṇḍalinī ascends. The pṛthvī-portion has already dissolved (the cascade of 6.299 will name it directly); what stands is a phantom that keeps the body's outline.

तैसें होय शरीर । तैं तें म्हणिजे खेचर । हें पद होतां चमत्कार । पिंडजनीं ॥२९६॥

And now the technical name arrives. "When the body becomes thus, then it is called khechara (sky-walker); this position, when it occurs, is a wonder among embodied beings (camatkāra piṇḍa-janīm)." Khecara — literally sky-moving — is a central Nāth-Siddha term for the attainment in which the body is no longer earth-bound; the khecarī-mudrā and the khecara-pada are core haṭha-yogic categories. Jñāneśvar's phrasing keeps the attainment firmly piṇḍa-janīm, "among the body-born" — the khecara-state belongs to the living body, not to a disembodied condition. This is the first explicit Nāth-siddhi technical-name in the cluster, the marker that we have entered the most overtly Nāth-tantric stretch of the whole work.

The siddhis as footprints left behind

देखें साधकु निघोनि जाये । मागां पाउलांची वोळ राहे । तेथ ठायीं ठायीं होये । अणिमादिक ॥२९७॥ परि तेणें काय काज आपणयां । अवधारीं ऐसा धनंजया । लोप आथी भूतत्रया । देहींचा देहीं ॥२९८॥

As the sādhaka rises, "he goes forth (nighōnī jāyē), and behind him a row of footprints remains (māgām pāuḷāmchī voḷ rāhē); there, place by place (ṭhāyīm ṭhāyīm), the aṇimādika arise." Aṇimādika is the technical prefix for the eight great siddhis — aṇimā, mahimā, laghimā, prāpti, prākāmya, īśitva, vaśitva, kāmāvasāyitā. They are figured here not as goals but as residue: footprints the ascending yogī leaves behind him as he climbs. The Yoga-sūtra's own warning frames the reading — the powers are upasarga, obstacles, "siddhis only in the extroverted state"; when celestials invite, the yogī takes no pride, lest he fall back. So Jñāneśvar immediately dismisses them: "but what use is that to oneself? Attend thus, Dhanañjaya" (parī tēṇēm kāya kāja āpaṇayām). The siddhis bloom at the spots he has already passed. The reader is being told, gently but firmly, not to stop at the footprints — the mat-samsthā of BG-6.15 lies further up.

And with that dismissal comes the announcement of the next operation: lōpa āthī bhūta-trayā dehīmchā dehīm — "the dissolution of the three elements is within the body, of the body." The doubled locative insists on it: this is not a metaphor for transcending the body but a process occurring inside the body. The bhūta-traya — the three lower mahābhūtas (earth, water, fire) — are about to dissolve.

The bhūta-laya cascade: element folding into element

पृथ्वीतें आप विरवी । आपातें तेज जिरवी । तेजातें पवनु हरवी । हृदयामाजीं ॥२९९॥ पाठीं आपण एकला उरे । परि शरीराचेनि अनुकारें । मग तोही निगे अंतरें । गगना मिळे ॥३००॥

Then comes one of the most technically precise laya-yoga passages in the corpus. "Water dissolves earth (pṛthvī-tēm āp viravī); fire absorbs water (āpā-tēm tēja jiravī); wind steals away fire, within the heart (tēja-tēm pavanu haravī hṛdayāmājīm)." Each gross element dissolves serially into the next-subtler one — the canonical bhūta-laya cascade of the Sāmkhya-Yoga and tantric traditions, the reverse-traversal of the evolutionary sequence by which the elements arose. The cascade is anchored in the hṛdaya, the heart-cakra. Then 6.300 completes it: wind alone remains (āpaṇa ēkalā urē), "but with the resemblance of the body" (śarīrāchēnī anukārēm) — pavana keeps the body's outer shape as a phantom-form — "and then it too departs inwardly and merges into the sky" (tōhi nigē antarēm gaganā miḷē). Four elements have now folded away; only ākāśa, the sky, remains as the substrate of the form.

This is the operational mechanism by which the deha resolves into its elements en route to the mat-samsthā state. It is worth noting that the same first step — water-and-earth kneaded into one — appeared earlier, at the kuṇḍalinī-arousal stage of the previous cluster; here it returns as merely one term of a far longer sequence. The arousal named the first step; the ascent names the whole cascade.

When the name "kuṇḍalinī" departs and "mārutī" takes over

ते वेळीं कुंडलिनी हे भाष जाये । मग मारुती ऐसें नाम होये । परि शक्तिपण तें आहे । जंव न मिळे शिवीं ॥३०१॥

Once the bhūta-laya is complete, the most explicit Nāth-tantric naming-instruction in the whole work arrives. "At that time the word kuṇḍalinī departs (kuṇḍalinī hē bhāṣa jāyē); then mārutī becomes the name (mag mārutī aisēm nāma hōyē); but her śakti-status remains (parī śakti-paṇa tēm āhē) until she merges into Śiva (jamva na miḷē śivīm)." This is a three-stage doctrine with all four terms named outright. Kuṇḍalinī names one stage — the coiled-serpent condition at the mūlādhāra. Mārutī — pure wind — names the next: she is now the suṣumnā-rising prāṇa, no longer coiled. And śakti itself persists as a status only until the final śiva-merger at the brahmarandhra. The name changes as the condition changes; "kuṇḍalinī" is not an eternal name but a stage-name. The Haṭha-yoga-pradīpikā's foundational image — the serpent-power upholding all yoga-tantras as the serpent-lord upholds the earth — is here operationally unfolded into this three-stage ascent, with the śakti-into-Śiva union of the Śiva-Samhitā waiting at the top.

Leaving jālandhara, piercing the ka-kārānta, riding the Omkāra

मग जालंधर सांडी । ककारांत फोडी । गगनाचिये पाहाडीं । पैठी होय ॥३०२॥ ते ॐ काराचिये पाठी । पाय देत उठाउठी । पश्यंतीचिये पाउटी । मागां घाली ॥३०३॥

Now the most explicit cakra-ascent in the corpus: three overt Nāth technical-events in one ovi. "Then she leaves jālandhara behind (jālandhara sāṇḍī); she breaks through the ka-kārānta (ka-kārānta phōḍī); she enters the sky-mountain (gaganāchiyē pāhāḍīm paiṭhī hōya)." The jālandhara-bandha is the chin-lock that seals the breath at the throat; she has passed beyond the throat-cakra, so she leaves it behind — the bandhas are developmental stations, not permanent fixtures. The ka-kārānta is the "terminus of the ka-syllable" — in the phonetic-yogic mapping where the alphabet maps onto internal cakras, the consonant-series ends at the brahmarandhra at the crown; ka-kārānta phōḍī is the brahmarandhra-piercing. And the gaganāchī pāhāḍ, the sky-mountain, is the sahasrāra-region she now enters.

The next ovi names the same ascent on its speech side. "She sets her foot upon the back of the Omkāra and rises one upon another (Omkārāchiyē pāṭhī pāya dēta uṭhā-uṭhī); the paśyantī-step she sets behind her (paśyantīchiyē pāuṭī māgām ghālī)." The Omkāra is the foundational parā-vāk of all utterance, the ladder she climbs. Paśyantī is the third of the four levels of speech — vaikharī (articulated), madhyamā (mental), paśyantī (the seeing-speech where the word is intuited as image), and parā (the unmanifest source). Passing paśyantī, she has traversed the three lower levels and approaches the unmanifest parā. The cakra-ascent is simultaneously a purification of speech: the locus-side (jālandhara, ka-kārānta, sahasrāra) and the vāc-side (Omkāra, paśyantī) are two faces of the same climb.

The river enters the ocean: tan-mātras filling the sky

पुढां तन्मात्रा अर्धवेरी । आकाशाच्या अंतरीं । भरती गमे सागरीं । सरिता जेवीं ॥३०४॥

The cascade now reaches its subtle stratum. "Then the tan-mātras, up to half (tan-mātrā ardhavērī), within the interior of the sky (ākāśāchyā antarīm), fill it — it seems as a river filling into the sea (bharatī gamē sāgarīm saritā jēvīm)." The tan-mātras are the subtle perceptive elements — sound, touch, form, taste, smell — that lie between the gross elements and the inner faculties. Here they fill the ākāśa the way a river fills the sea. The qualifier ardhavērī, "up to half," is exact: this is a partial merger, the tan-mātras flowing into the sky as a river flows into the ocean before becoming sea. The canonical samarasa image — the river entering the ocean — is here used not for the final merger but for this midway event. The Bṛhadāraṇyaka's salt-lump dissolving in water supplies the underlying dissolution-doctrine. In the bhakti register, Tukaram's most-celebrated samarasa abhang (2474, per the frontmatter's tukaram_parallel — the salt-into-water, camphor-into-flame, one-flame text) names the same river-into-ocean dissolution-into-the-medium, though Tukaram frames it as jīva-into-Deva where Jñāneśvar frames it as tan-mātra-into-ākāśa.

The embrace in the brahmarandhra: sō'ham-bhāva spreads its arms

मग ब्रह्मरंध्रीं स्थिरावोनी । सोऽहंभावाच्या बाह्या पसरुनी । परमात्मलिंगा धांवोनी । आंगा घडे ॥३०५॥

This is the climactic event of the cluster. "Then, becoming stable in the brahmarandhra (brahmarandhrīm sthirāvōnī), spreading the arms of the sō'ham-bhāva (sō'ham-bhāvāchyā bāhyā pasarunī), running to the paramātma-linga (paramātma-lingā dhāvōnī), her form meets and fits with it (āngā ghaḍē)." Three overt technical-events. The brahmarandhra is the cranial aperture at the crown, the terminus of the suṣumnā in the sahasrāra; she stabilizes there. The sō'ham-bhāva — "I am That," the foundational mahā-vākya identification, the meditative form of aham brahmāsmi and of the hamsa breath-mantra rising in the suṣumnā — is here astonishingly anthropomorphized: the bhāva is given arms which she spreads in an embracing posture. And the paramātma-linga — the formless-form of the paramātman, imaged through the linga, the classical aniconic marker of Śiva — is the target she runs to and merges with. This is the explicit śakti-Śiva yāmala, the union; the "until she merges into Śiva" of 6.301 is here fulfilled. In the bhakti key, the frontmatter notes Tukaram 2917 (the bhakti-non-dualism text — "you speak with my mouth; I in you; the difference only in naming") as a thematic parallel: the same non-dual fruit, named in the sahaja-vinōda mode rather than the tantric-laya mode.

The curtain falls: samarasa exhausts even the sky

तंव महाभूतांची जवनिका फिटे । मग दोहींसि होय झटें । तेथ गगनासकट आटे । समरसीं तिये ॥३०६॥ पैं मेघाचेनि मुखीं निवडिला । समुद्र कां वोघीं पडिला । तो मागुता जैसा आला । आपणपयां ॥३०७॥ तेवीं पिंडाचेनि मिषें । पदीं पद प्रवेशे । तें एकत्व होय तैसें । पंडुकुमरा ॥३०८॥

After the embrace, the substrate of perception itself evaporates. "Then the curtain of the mahābhūtas falls away (mahā-bhūtāñchī jāvanikā phiṭē); then the two have a sudden striking-together (dōhīmsī hōya jhāṭēm); there, even the sky is exhausted in that samarasa (gaganāsakaṭa āṭē samarasīm tiyē)." The mahābhūtas were a jāvanikā, a curtain, an occluding fabric; it falls. The "two" — śakti and Śiva, jīva and paramātman, the ascending form and the paramātma-linga — meet in an immediate conjunction. And even gagana, the last subtle element that had remained, is āṭē — exhausted, completely poured out — in the samarasa. This is the laya-yoga technical term for the final substance-into-substance merger where even the subtlest remaining element is swallowed. Here Jñāneśvar's technical vocabulary aligns verbally, not merely thematically, with Tukaram's most-celebrated samarasa text (2474): both use samarasa itself as the name for the final non-residual merger.

Then two images close the merger-doctrine. First the cloud-and-sea cycle: the sea, "selected by the mouth of the cloud" (meghāchēni mukhīm niravadiḷā), fallen in streams, returns at last to itself (māguṭā jaisā ālā āpaṇapayām). The apparent-other was always the self; the departure was always a detour. And then its direct application: "similarly, through the pretext of the piṇḍa, the pada enters into the pada — that oneness becomes, O son of Pāṇḍu" (tēvīm piṇḍāchēnī miṣēm padīm pada pravēśē tēm ēkatva hōya). The body, the piṇḍa, was the miṣa — the pretext, the staged occasion — by which the paramātman traversed an apparent arc to re-enter itself. This is the philosophical warrant for the entire embodied-yoga path: the body is not an obstacle to be discarded but a pretext-vehicle whose whole function is to enable the return-to-self. BG-6.15's mat-samsthām adhigacchati is here rendered as exactly this: pada entering pada, the yogī entering the very station of Kṛṣṇa that he never truly left.

Sky into sky: the realization is by becoming, not by knowing

आतां दुजें हन होतें । कीं एकचि हें आइतें । ऐशिये विवंचनेपुरतें । उरेचिना ॥३०९॥ गगनीं गगन लया जाये । ऐसें जें कांहीं आहे । तें अनुभवें जो होये । तो होऊनि ठाके ॥३१०॥

After the merger, even the question collapses. "Now — was there a second? Or was this one ready from the start? — for the purpose of such an inquiry, nothing at all remains over (aiśiyē vivancanē-puratēm urē-chīnā)." The advaita-vicāra finds no foothold: there is no two from which to ask "was there ever two," and no separate one from which to ask "was it always one." The very instrument of inquiry presupposed the duality it was meant to investigate, and that duality is gone.

And the positive formulation: "Sky goes to dissolution into sky (gaganīm gagana layā jāyē) — whatever such-thing there is, whoever becomes it by experience, becomes it and stands as it (anubhavēm jō hōyē tō hōūnī ṭhākē)." Even ākāśa is laya'd into ākāśa — the last self-referential dissolution, no residue at the most subtle stratum. And the access to it is not cognition but identity: the realization is not-knowable but becomable. The only way to reach it is to become it. The Chāndogya's image of the serene one who, having reached the supreme light, "fully becomes by his own form," and the Yoga-sūtra's samāpatti — knowledge by the meditator's being colored into identity with the object — both stand behind this. Knowledge here is by becoming, not by content.

Speech turns back: the via-negativa stretch

आतां महाशून्याचिया डोहीं । जेथ गगनसीचि थावो नाहीं । तेथ तागा लागेल काई । बोलाचा इया ? ॥३१५॥

Having described all this, the commentator's own speech now fails before it — and Jñāneśvar makes that failure itself the subject of a long stretch (6.311-6.322). The mātu, the talk of that place, cannot be grasped by the hand of speech; the realization belongs to anubhava, not to samvāda, conversation. The vaikharī — the articulated, lowest level of speech — has "stood far off" (vaikharī durī ṭhēlī); where the ascending yogī passed paśyantī on the way up, the would-be speaker finds even vaikharī receded on the way to expression: two inverse traversals of the same fourfold vāc-hierarchy. Behind the eyebrow-creeper (the ājñā-cakra), even the body of the ma-kāra — the closing m of Om, which would naturally arise at the brow — does not establish itself, because the solitary prāṇa has already overrun it as it strains up into the sky. Then the lamp of speech sets (śabdāchā divō māvaḷalā), as the sun sets; and beyond even that, the exhaustion of ākāśa comes on.

And the most radical formulation: "Now, in the deep pool of the mahā-śūnya (mahā-śūnyāchiyā ḍōhīm), where even the sky has no footing — there, what mooring-line of speech could ever reach (tāgā lāgēla kāī bōlāchā)?" The mahā-śūnya, the great void, is the Nāth-Mādhyamika term for the terminal locus beyond ākāśa, a bottomless ḍōha (pool) into which speech can drop no measuring-line. The realization cannot be caught in letters or reached by the ear; it arrives only when fortune (daiva) grants it, and then one must simply stand as it, having become it. Speech recedes, the lifespan of sankalpa ends, even the wind of vichāra cannot enter. This is the canonical via-negativa triad against the three instruments of cognition — language, will, and reasoning.

जें उन्मनियेचें लावण्य । जें तुर्येचें तारुण्य । अनादि जें अगण्य । परमतत्त्व ॥३२०॥

Yet the negation is not the last word. Jñāneśvar names the parama-tattva positively, pairing the Nāth and Vedānta terminal-states: "that which is the radiance (lāvaṇya) of the unmanī-state, that which is the youthful-vigor (tāruṇya) of the turyā — beginningless, uncountable, the supreme-principle." Unmanī — the no-mind state, the terminal goal of haṭha-yoga — and turyā — the fourth state beyond waking, dream, and deep sleep — are both named outright, and the parama-tattva is named as the very loveliness and vigor that make these states what they are. This pairing of the haṭha unmanī and the Vedāntic turyā is a characteristic paramparā-synthesis. The supreme principle is then named as the root of the universe, the fruit of the yoga-tree (yoga-drumāchēm phaḷa — the cluster naming itself: yoga is a tree, this realization is its fruit), the pure caitanya of ānanda, the frontier of form, the solitude of mokṣa, the place where beginning and end have dissolved, the seed of the mahābhūtas, the tejas of the great tejas — and, finally, "my own essential form" (nija svarūpa mājhē), as the Kṛṣṇa-voice resumes with the pārtha vocative, drawing on BG-10.39's "the seed of all beings, that I am" and BG-15.12's "that tejas, know it as mine."

The bhakti pivot: the four-armed form blooms in devotees' eyes

ते हे चतुर्भुज कोंभेली । जयाची शोभा रूपा आली । देखोनि नास्तिकीं नोकिलीं । भक्तवृंदें ॥३२४॥

Then the cluster turns, suddenly and decisively, away from pure negation. The parama-tattva just named through this whole via-negativa stretch is — this very caturbhuja, the four-armed form. "This four-armed one has sprouted (chaturbhuja kōmbhelī), whose beauty has come into form; the groves of devotees, seeing it, the nāstikas reviled (nāstikīm nōkilīm bhakta-vṛndēm)." The realized formless form blooms as the saguṇa, four-armed Vaiṣṇava figure — and it blooms only in the eyes of devotees. The bhakta-vṛnda, the grove of the faithful, sees what the nāstika cannot. This is the bhakti-eruption that rescues the cluster from ending in bare void, the same bhakta-eye that Tukaram (2787, per the frontmatter) names in the redemption-of-the-fallen, visible only to devotion's sight.

परब्रह्माचेनि रसें । देहाकृतीचिये मुसें । वोतींव जाहले तैसे । दिसती आंगें ॥३२७॥

And the doctrine of the embodied realized one — the jīvan-mukta — is given its most beautiful image. Those who have done this sādhana in the body "appear, in their very bodies, as though cast out of the molten essence of para-brahman, poured into the mould of the body-form" (para-brahmāchēnī rasēm dēhākrtīchiyē musēm vōtīmva jāhalē). The rasa is the liquid essence; the muse is the mould; the realized body is a casting of para-brahman-essence into the deha-shape. The piṇḍa-as-pretext of 6.308 is here developed into the piṇḍa-as-mould: the body is not discarded but becomes a transparent statue of para-brahman, a vessel that has taken the very shape of the realized essence.

"Am I even qualified?" — the democratization of yogyatā

आतां कृष्णा तुवां सांगितला योगु । तो मना तरी आला चांगु । परि न शकें करूं पांगु । योग्यतेचा ॥३३३॥

The cluster then closes, over its final stretch, with Arjuna's anxiety. Having heard the whole ascent, he confesses: "Now, Kṛṣṇa, the yoga you have told — it has pleased my mind well; but I cannot manage the pāngu of yogyatā" — I cannot lay claim to the fitness such a path seems to require. He frames the worry sharply: if it can be practiced only by the fit, and fitness is some elite prerequisite I lack, then is the whole thing closed to me? He even offers a fallback — if natural ability would do, he would gladly practice this easy path; but if not, he must ask what to do without it.

Kṛṣṇa's answer is quietly radical. "This work is indeed the final goal (nirvāṇa); but even ordinary, lesser things — do they ever reach completion without the adhikāra being placed?" Then he dismantles the premise. Yogyatā, fitness, is not a separate inborn endowment one either has or lacks; yogyatā is subordinate to attainment — for fitness is made in the very undertaking, the way a thing begun bears its fruit. There is no readymade stock of fitness lying about, no quarry of qualification to be mined. The one criterion is given plainly: "let a man become for a moment dispassionate (viraktu), restrained in the ways of the body (dehadharmīm niyatu) — is he not then exactly the rightful one (adhikāriya)?" By so small a turning, "fitness is yours too" (yogyapaṇa tūtēmhi jōḍē). And the converse, stated as the cluster's terminal line: "to the unrestrained (aniyatā), there is no yogyatā at all." Fitness is not birthright but the fruit of niyama — restraint — the very niyata-mānasaḥ ("of restrained mind") that BG-6.15 named as the yogī's own qualifier. The path is not closed to anyone who will undertake the restraint.

Cluster summary

Core teaching. BG-6.15 — "the constantly-yoked yogī of restrained mind attains the peace, culminating in nirvāṇa, that abides in Me" — is unfolded as the corpus's most explicit kuṇḍalinī-ascent. The śakti's radiance withdraws and the body becomes invisible (khecara); the four lower elements dissolve cascade-wise into the sky; the name kuṇḍalinī yields to mārutī as she rises in the suṣumnā; she leaves the jālandhara-bandha, pierces the ka-kārānta (brahmarandhra), rides on the Omkāra's back and steps past paśyantī; she stabilizes in the brahmarandhra and embraces the paramātma-linga with the arms of sō'ham-bhāva; the curtain of the elements falls and the samarasa exhausts even the sky. The realization that follows is reached by becoming, not by knowing — sky dissolving into sky. After a via-negativa stretch in which speech, will, and reasoning all turn back before the mahā-śūnya, the cluster pivots through the bhakti-vision of the four-armed form blooming in devotees' eyes and the jīvan-mukta as a casting of para-brahman-essence in the body-mould — and closes with Arjuna's anxiety about yogyatā and Kṛṣṇa's answer that fitness is not an elite prerequisite but arises in the very undertaking of restraint.

Chapter-arc position. This is the culmination-śloka of chapter 6's first arc — the technical-yoga arc that opened with the prepared seat (BG-6.11-12) and proceeded through body-straightness and the brahmacarya-vrata (BG-6.13-14). BG-6.15 delivers the terminal fruit (nirvāṇa-paramā śānti, mat-samsthā), and Jñāneśvar uses the delivery to give his longest and most explicit kuṇḍalinī-ascent, cakra-piercing, and samarasa-completion stretch in the entire corpus (6.293-6.310), with a density of Nāth-tantric technical vocabulary — kuṇḍalinī, mārutī, jālandhara, ka-kārānta, brahmarandhra, sō'ham-bhāva, paramātma-linga, paśyantī, mahā-śūnya, unmanī, turyā, samarasa — unmatched elsewhere. The closing yogyatā-dialogue (6.326-6.344) then bridges directly to BG-6.16, where Kṛṣṇa will specify what niyata — restraint — operationally means in food, sleep, and effort: "yoga is not for the over-eater, nor for the one who eats nothing." The ascent will not be repeated; the chapter now returns to the regimen of restraint that makes a yogī fit.
