Bhagavad Gītā Chapter 2, Verse 48: Krishna to Arjuna — Sāṅkhya-Yoga
Stand firm in yoga, act without clinging to outcomes, Arjuna, and meet success and failure with the same mind. That evenness of spirit is what yoga means.
Bhāṣyakāra purports
- Śaṅkaraadvaita
Established in yoga (yogasthaḥ — poised in the equanimity that IS yoga), perform actions for Īśvara alone, Dhanaṃjaya, having abandoned saṃga (attachment, the adhesion of ego to result). Śaṅkara is precise: siddhi here means the attainment of sattva-śuddhi (purity of mind that matures into jñāna), and asiddhi is its frustration — both must leave you unmoved, sama (equal, identical in weight). This equanimity is not a mood but the very definition Kṛṣṇa now supplies: samatvaṃ yoga ucyate — sameness-toward-outcomes is what the word yoga names here, preparing the sādhaka for the jñāna that alone is liberation.
- Rāmānujaviśiṣṭādvaita
Rāmānuja opens with the relational field Arjuna must release — rājya, bandhu (kingdom, kinsmen) — the particular objects of saṃga that chain the will to outcomes. Standing in yoga (yogasthaḥ), he says, means the mind has achieved citta-samādhāna (composed settledness) as its own intrinsic form (samatva-rūpam), not a forced suppression but an organically stable equipoise. In that composure, victory and defeat in battle — the siddhi-asiddhi of the warrior's kainkarya (devoted service) — become genuinely equal, because the action's purpose is already fulfilled in its offering to Bhagavān.
- Madhvadvaita
Madhva reads yogasthaḥ as upāya-sthaḥ — 'abiding in the means,' meaning the jīva (soul, eternally distinct from Hari) stations itself within the approved instrument of Hari's worship. Saṃga is glossed with surgical economy as phala-sneha, affection for the fruit, which is severed not by abstraction but by the jīva's recognition that it cannot own what belongs to Hari. Siddhi and asiddhi are then cosmologically equal because both outcomes are Hari's disposition of his own sovereignty — the dependent jīva's equanimity is not achieved but yielded into.
- Vallabhaśuddhādvaita
Vallabha pivots the entire verse on the phrase mad-yoga-sthaḥ — abiding in My yoga, meaning immersed in the Lord's own bliss-form (phala-svarūpa yoga). The abandonment of saṃga toward fruits is not renunciation in the austere sense but the natural stance of one who has received Kṛṣṇa's prasāda-śakti (grace-power): outcomes lose their grip because the recipient already overflows with what the fruit pretended to offer. Mano-nirodha (the stilling implied by samatva) happens as a consequence of this flooding grace, not as an effort the sādhaka manufactures.
- Śrīdharabhakti
Śrīdhara defines yogasthaḥ directly as paramaiśvara-ekaparatā — single-pointed refuge in the Supreme Lord alone, making yoga here an abidance in devotional relationship rather than a mental technique. Saṃga is unpacked with characteristic philological care as kartṛtva-abhinivelśa, the ego-insistence that 'I am the doer,' which must be released alongside fala-tṛṣṇā (thirst for results) so that action becomes kevalam-Īśvarārpaṇa (pure offering to the Lord). The sādhus (realized beings), he adds, call this samatva yoga precisely because the mind achieves citta-samādhāna-rūpatva — the form of composed-mind settledness — through Īśvara-ekāśraya alone.
- Madhusūdanaadvaita-bhakti
Madhusūdana holds both poles simultaneously: saṃga is defined as both phala-abhilāṣa (desire for results) and kartṛtva-abhinivelśa (ego-insistence on doership), and their joint renunciation enables kevalam-Īśvara-ārādhana-buddhyā karmāṇi kurvit — action performed under the sole cognitive frame of worship of Īśvara. He then does what the Bhāṣyakāra (Śaṅkara) himself notes: the second half of the verse (samatvaṃ yoga ucyate) is the explicit commentary on the first half's yogasthaḥ, resolving any apparent redundancy — yoga in the imperative instruction is definitionally identical with this very samatva of siddhi-asiddhi, and the range widens from the battle's jaya-ajaya to all seen and unseen results (dṛṣṭa-adṛṣṭa-sarva-phala-parityāga).
