Bhagavad Gītā Chapter 2, Verse 31: Krishna to Arjuna — Sāṅkhya-Yoga
Look at your own dharma and do not tremble, for a warrior has no higher good than a battle that is righteous.
Bhāṣyakāra purports
- Śaṅkaraadvaita
Śaṅkara reads the svadharma argument as secondary scaffolding: yuddha (battle) is the kṣatriya's svābhāvika (natural) dharma — not because varṇa-obligation is ultimate, but because it aligns action with the ātman's own nature (ātmasvābhāvya), clearing the path for jñāna. The verse thus addresses the surface-level bhrama (confusion) of one who conflates personal grief with a universal prohibition on violence, before the deeper ātma-vicāra dissolves the agent altogether. For Śaṅkara, the śreyas (highest good) that no alternative to yuddha can supply is not victory but the niṣkāma state that dharmic action, when performed without trembling, makes possible.
- Rāmānujaviśiṣṭādvaita
Rāmānuja reads yuddha as a full analogue of Vedic yajña: just as the agni-ṣomīya (Vedic Soma sacrifice) involves prāṇi-māraṇa (killing of an animal) that is nonetheless dharmic by śruti-injunction, so too this battle — svadharma avekṣya (considered in light of one's own dharma) — is an act of kainkarya (service) to Bhagavān, not violence. The Yajur-Veda passage he cites (na vā u etanmriyase, 4.6.9.43) guarantees the slain a sугебhi (auspicious path), parallel to the verse's own promise of elevated rebirth. For Rāmānuja, the śreyas (highest good) that no alternative can furnish is the kṣatriya's complete fulfilment of the svabhāva-ja (nature-born) duties enumerated at 18.43 — śaurya (valour), tejā (energy), dhṛti (firmness), dākṣya (skill), and appalāyana (non-flight in battle) — each of which is itself a face of Bhagavān's guṇa.
- Madhvadvaita
*Sva-dharma* (one's own assigned station) is not self-authored: for the *paratantra* *jīva* (the eternally dependent individual self), it is Hari's *svabhāva-kṛta vyavasthā* (nature-constituted ordering) that fixes the *kṣatriya*'s function as warfare. *Vikampitum* — to waver — is therefore not mere timidity but a refusal of the station Bhagavān has assigned according to *taratamya* (graded ontological hierarchy). The mūla's declaration — *dharmyād dhi yuddhāc chreyo 'nyat kṣatriyasya na vidyate* — carries full ontological weight: because the *jīva*'s very being is *paratantra*, there is genuinely no higher good available to it outside the function allotted by Hari. To abandon *yuddha* is not a private moral failure but a rupture in the *pañca-bheda* (the five-fold real distinction) order, a refusal of *bhakti* expressed through action. *Sva-dharma*, rightly seen, is the *kṣatriya jīva*'s mode of ontological subordination to *svatantra* Hari.
divergence: Bucket changed from B to C: no Madhva or Jayatīrtha bhāṣya prose exists for this verse. The reading is voiced directly from Dvaita *siddhānta* applied to the mūla.
- Vallabhaśuddhādvaita
Vallabha reads the verse as a correction of Arjuna's dharmabhraṃśa (falling away from dharma): the vepathus (trembling) and romāñca (horripilation) described in 1.29 were symptoms of a dharma-niṣṭha (one grounded in dharma) forgetting his station, and the present verse restores him by pointing to svadharma as Kṛṣṇa's own prasāda-rūpa (form of grace). In Puṣṭi-mārga, neither the varṇa-argument nor the ātma-argument is the deepest ground; the deepest ground is that Kṛṣṇa himself is both the ādeśa (command) and the śakti (power) to execute it, so the kṣatriya who fights without vikampana (trembling) is already flowing in the current of Kṛṣṇa's līlā (divine play). The śreyas is thus neither jñāna nor duty-fulfilment but the grace-sustained anupraveśa (entry) into Kṛṣṇa's own desire.
- Śrīdharabhakti
Śrīdhara anchors the verse between two of Arjuna's prior complaints — the vepathus-romāñca (trembling-horripilation) of 1.29 and the na śreyo'nupaśyāmi (I see no good in killing kinsmen) of 1.31 — and shows that both dissolve before the double argument of 2.31: ātmā cannot be destroyed (so the trembling is unfounded), and the yuddha is dharmānapeta (not departing from dharma, i.e., fully lawful). The phrase dharmyād yuddha (battle grounded in dharma) is rendered by Śrīdhara as nyāyya (just/proper), a juridical term meaning the action conforms to both śāstra and svabhāva. For the bhakti-philological school, śreyas (highest good) here carries a double valence: it names the kṣatriya's this-worldly excellence and simultaneously points, through the grammar of the comparative, toward the path of bhakti that the Gītā will fully disclose.
- Madhusūdanaadvaita-bhakti
Madhusūdana frames the verse at the hinge of two remedies: the upādhitraya-viveka (discrimination of the three adjuncts — gross body, subtle body, avidyā) was the ātmajñāna remedy for Arjuna's sādhāraṇa-bhrama (universal confusion); now the present verse addresses his asādhāraṇa-bhrama (personal confusion specific to him) — the appearance that his yuddha is adharma because of its hiṃsā-bahulya (preponderance of violence). Madhusūdana cites Parāśara and Manu to establish that kṣatriya-yuddha is praja-rakṣaṇa (protection of subjects) and brāhmaṇa-śuśrūṣā (service to brāhmaṇas), making it not merely permitted but praśastatara (more commended) than any alternative. The advaita-bhakti synthesis lies in the structure: Śaṅkara's non-dual ātman dissolves the agent; Kṛṣṇa as Bhagavān furnishes the compassionate command; together they leave Arjuna neither a karmin bound by duty nor a jñānin above it, but a devotee who acts from the clarity of both.
