Bhagavad Gītā Chapter 8, Verse 26: Krishna to Arjuna — Akṣara-Brahma-Yoga

Bhāṣyakāra purports

• Śaṅkaraadvaita

  These two cosmic paths — śuklā (bright, luminous with jñāna) and kṛṣṇā (dark, devoid of it) — are eternal because saṃsāra itself is beginningless. Śaṅkara insists the paths belong specifically to adhikārins (qualified practitioners) of jñāna-karma, not to all beings indiscriminately. By the bright path one attains anāvṛtti (non-return to rebirth); by the dark one returns again — and since Brahman alone is real, 'return' is re-immersion in avidyā-driven cycle.

  divergence: Śaṅkara: 'ज्ञानप्रकाशकत्वात् शुक्ला तदभावात् कृष्णा' — bright because it illumines, dark through absence of that illumination; 'शाश्वते नित्ये संसारस्य नित्यत्वात्' — eternal because saṃsāra is eternal.

• Rāmānujaviśiṣṭādvaita

  The bright path is arcirādi-gati (the path of flame, light, day, etc.) and the dark is dhūmādi-gati (smoke, night, etc.); Rāmānuja explicitly roots both in Chāndogya 5.10, confirming śruti-sanction. Those who worship Bhagavān with śraddhā and tapas in the forest travel the bright path to Brahmaloka and beyond; those performing iṣṭāpūrta in the village return by the dark. The distinction is not merely ritual but ontological — the bright path leads to Bhagavān's own realm, while the dark perpetuates dependent jīva existence.

  divergence: Rāmānuja: 'शुक्लया अनावृत्तिं यान्ति कृष्णया तु पुनः आवर्तन्ते' and Chāndogya citation 5.10.1 and 5.10.3 — shruti confirms both paths as śāśvata.

• Madhvadvaita

  *Śukla-kṛṣṇe gatī* — the bright and dark *gatī*s (paths) — are *śāśvate* (eternal), not contingent constructions. The *jagat* (world of transmigrating beings) is governed by these two paths because *pañca-bheda* (the five-fold real distinction) is never dissolved: *jīva* and *Īśvara* remain ontologically separate in all states. By the bright path, the *jīva* reaches *anāvṛtti* (non-return) — arrival in Viṣṇu's *nitya-dhāma* (eternal abode) — not through any autonomous capacity but through Hari's *anugraha* (grace), which alone breaks the *jīva*'s *paratantra* (eternal dependence on the Lord) loose from *saṃsāra*'s pull. By the dark path, *āvartate punaḥ* (it returns again): *karma* and the absence of *bhakti* as ontological subordination return the *jīva* to rebirth. The two paths are *śāśvata* (eternal and real), not provisional *māyā*-constructs — their eternality reflects the real, graded *taratamya* (ontological hierarchy) that obtains between *svatantra* Hari and all *paratantra* souls.

  divergence: No Madhva or Jayatīrtha bhāṣya survives for this verse; the reading derives directly from core dvaita-siddhānta applied to the mūla — pañca-bheda, taratamya, and Hari-anugraha as the sole basis of anāvṛtti.

• Vallabhaśuddhādvaita

  Vallabha reads the two paths as rooted in the nature of light and darkness themselves: śuklā is prakāśamaya (made of light, of Kṛṣṇa's own svarūpa-śakti), kṛṣṇā is tamomaya (suffused with tamas). The concluding upasaṃhāra (summary) of this mārga-dvaya signals that all path-talk is ultimately Kṛṣṇa's own līlā — the bright path is not earned but gifted as prasāda to those in Bhagavān's puṣṭi (nourishing grace).

  divergence: Vallabha: 'उभयोः प्रकाशतमोमयत्वाद्भेदः' — the distinction between the two paths is grounded in their being made of light and darkness respectively.

• Śrīdharabhakti

  Śrīdhara names the bright path arcirādi (light-series) and the dark dhūmādi (smoke-series), calling them the domains of jñāna-karma-adhikārins respectively, both paths anādi (beginningless) like saṃsāra itself. The bright leads to mokṣa as nivṛtti; the dark to punar-āvṛtti (re-return). Śrīdhara's balanced voice holds both paths as śāśvata-sammata — eternally recognized by śruti — without privileging one over the other, leaving open that the genuine bhakta transcends the binary.

  divergence: Śrīdhara: 'एते गती मार्गौ ज्ञानकर्माधिकारिणो जगतः शाश्वतेऽनादी संमते संसारस्यानादित्वात्' — both paths are beginningless and śruti-sanctioned.

• Madhusūdanaadvaita-bhakti

  Madhusūdana reads śuklā as ज्ञानप्रकाशमयी (luminous with jñāna-light) and kṛṣṇā as ज्ञानहीनतमोमयी (darkness born of jñāna-absence) — explicitly linking epistemological illumination to the cosmological path. He broadens the adhikāra to include 'all who know the śāstra' (शास्त्रज्ञस्य), not just specialists. His synthesis holds: the bright path is for saguṇa-vidyā and karma practitioners who nonetheless orient toward Brahman, while the dark path captures all who act without that orientation — the synthesis leaves bhakti as the fastest route to śuklā-gati.

  divergence: Madhusūdana: 'ज्ञानप्रकाशमयत्वात् ... ज्ञानहीनत्वेन तमोमयत्वात्' and 'सगुणविद्याकर्माधिकारिणोः जगतः सर्वस्यापि शास्त्रज्ञस्य' — jñāna-light vs jñāna-absence as the operative distinction.
