Bhagavad Gītā Chapter 8, Verse 25: Krishna to Arjuna — Akṣara-Brahma-Yoga

Bhāṣyakāra purports

• Śaṅkaraadvaita

  Śaṅkara reads each term — dhūma (smoke), rātri (night), kṛṣṇa (dark fortnight), and the six months of dakṣiṇāyana — not as literal cosmological stations but as the presiding deities (abhimāni-devatā) of those phenomena, who conduct the departing soul along the pitṛyāna. The karmī who performs iṣṭa (Vedic rite) and pūrta (charitable work) reaches the cāndramasa-jyotis, enjoys the fruit of merit, and upon its exhaustion returns (nivartate) to rebirth. For Śaṅkara the contrast with 8.24 is stark: the jñānī who traverses the arcirādi-mārga does not return; the sakāma-karmī always does — hence the verse functions as a refutation-by-contrast urging the student toward jñāna.

• Rāmānujaviśiṣṭādvaita

  Rāmānuja's gloss is deliberately compressed: this verse simply exhibits the pitṛloka-ādi stations on the dhūmādi-mārga, and the term yogī here means one whose 'yoga' is punya-karma — meritorious ritual action — rather than the niṣkāma-upāsaka of 8.24. The soul's return from candraloka is not a cosmological accident but a consequence of acting for personal fruit rather than as kainkarya (service) to Bhagavān; the path itself is Bhagavān's ordination, but the traveller on it is still bound by svārtha (self-interest). Rāmānuja's brevity signals that the verse needs no elaborate treatment: it serves as the foil that makes the archirādi-mārga's irreversibility theologically luminous.

• Madhvadvaita

  [NOTE: Madhvācārya did not compose a bhāṣya on this verse; the following is constructed from Dvaita doctrinal principles.] In Dvaita logic the soul traversing the pitṛyāna is a nitya-baddha jīva whose karma-phala is real and distinct from Hari's own will; the cāndramasa-jyotis is an actual loka governed by a deity who is herself a dependent instrument (paratantra) of Viṣṇu. Return (nivartate) confirms the jīva's essential difference (bheda) from Brahman: only the mukta reaches Vaikuṇṭha and never returns, whereas the sakāma traveller oscillates in saṃsāra because his very action is motivated by ego-possession rather than surrender to Hari.

• Vallabhaśuddhādvaita

  Vallabha frames this verse as the āvṛtti-mārga of the sakāma-agnihotrin — one who performs Vedic rites with desire — and maps three grades of return: the sātvikī path (niṣkāma karma with Bhagavad-arpaṇa, leading to krama-mukti), the rājasī path (kāmya-karma → candraloka → bhoga → āvṛtti), and the tāmasī path (prohibited action → naraka-bhoga → āvṛtti). The dhūmādi sequence is the Śruti-declared rājasī corridor; the pivotal insight is that even this corridor is Kṛṣṇa's līlā-prasāda — the universe arranges itself to exhaust karma and return the jīva until it surrenders to puṣṭi-bhakti, the only path that dissolves the cycle entirely.

• Śrīdharabhakti

  Śrīdhara Svāmī identifies four presiding deities (abhimāninī-devatā): dhūma, rātri, kṛṣṇa-pakṣa, and the six-month dakṣiṇāyana, echoing the Chāndogya-śruti (te dhūmam abhisambhavanti… pitṛlokāc candram). The karma-yogī who travels this path reaches the cāndramasa-jyotis — the lunar loka — enjoys the fruit of iṣṭa-pūrta karma, and returns. Śrīdhara then explicitly maps all four exit-types: nivṛtti-karma with upāsanā → krama-mukti; kāmya-karma → svarga-bhoga → āvṛtti; niṣiddha-karma → naraka → āvṛtti; kṣudra-karma → immediate rebirth without cosmic travel. The verse thus situates the pitṛyāna within a complete graduated soteriology, with bhakti-informed upāsanā as the only route to permanent liberation.

• Madhusūdanaadvaita-bhakti

  Madhusūdana reads the verse as a deliberate foil to glorify the devayāna: the pitṛyāna's four named deities (dhūma, rātri, kṛṣṇa-pakṣa, dakṣiṇāyana) are explicitly called upalakaṣaṇa — indicators pointing to the fuller Chāndogya list (pitṛloka, ākāśa, candramā). The karma-yogī who performs iṣṭa-pūrta-dāna reaches the cāndramasa-jyotis, dwells there yāvat-sampātam (until karma is exhausted), and returns — the term sampāta (the karma that depletes) marking the precise mechanism of inevitable return. The structural purpose is rhetorical: anāvṛtti-mārga (8.24) is proven superior by contrast, and Kṛṣṇa-bhakti, which grants that anāvṛtti, emerges as the culmination of both jñāna and karma disciplines.
