Bhagavad Gītā Chapter 2, Verse 19: Krishna to Arjuna — Sāṅkhya-Yoga
Whoever thinks this self is a killer, and whoever thinks it can be killed, both are wrong. It neither kills nor is killed.
Bhāṣyakāra purports
- Śaṅkaraadvaita
Whoever supposes this ātman to be a killer, and whoever supposes it to have been killed, both mistake the body-bound ego-sense (ahampratyaya) for the self — they do not know ātman at all. Because ātman is avikriya (changeless, incapable of modification), it neither performs the act of killing nor undergoes it as patient; superimposing killing-agency onto it is no different from superimposing agency onto the sky.
divergence: Advaita locates the error in avidyā-driven identification of ātman with the body. Agency and patient-hood are vivarta (apparent), not real. No devotional relation to Kṛṣṇa is in view — the teaching is pure tattva-viveka (discernment of truth).
- Rāmānujaviśiṣṭādvaita
The one who thinks this ātman — whose nature has already been declared as eternal and unchanging — to be a cause of killing (hananakāraṇa), and the one who thinks it to have been killed, both fail to understand it truly. Since hanti denotes only the bringing about of bodily separation (śarīraviyogakaraṇa), and since ātman is eternal by its very nature (nityatva), no cause whatsoever can make ātman either the instrument or the recipient of such a separation.
divergence: Rāmānuja preserves the real ontological existence of jīvātman as a viśeṣaṇa (attribute/mode) of Brahman. Unlike Advaita, the jīva genuinely exists and genuinely serves; the error is misidentifying what kind of entity it is, not denying its existence. The śāstra citations (na hiṃsyāt sarvā bhūtāni) anchor the reading in dharmaśāstra as well.
- Madhvadvaita
The ordinary transaction (vyavahāra) of ‘killing' and ‘being killed' is a confusion (bhrānti): jīva is a reflection (pratibimba) of Hari the original (bimba), and a reflection performs no action of its own — it moves only because the original moves. Therefore this ātman neither kills nor is killed, for, as the Bṛhadāraṇyaka Upaniṣad teaches, it only ‘appears to think' (dhyāyatīva) — all action belongs to Hari alone.
divergence: Madhva's pratibimba-vāda makes agency a metaphysical impossibility for the jīva as such. This is sharper than Advaita: not merely that ātman is beyond change, but that any appearance of jīva-agency is ontologically dependent on Hari's independent action. Dvaita is the most polemically explicit school here.
- Vallabhaśuddhādvaita
One who ascribes the status of killer or killed to this ātman is censured here, because the root han (hanti) means causing the separation of a composite, limbed body (sāvayava-śarīra-viyoga) — and ātman has no such body to be separated from. The scripture's prohibition ‘one must not injure all beings' (na hiṃsyāt sarvā bhūtāni) is also intelligible only with reference to the body, not to ātman itself.
divergence: Vallabha's Puṣṭi-mārga reads this as protecting Kṛṣṇa's sovereignty over all manifestation — ātman belongs wholly to Kṛṣṇa, and Kṛṣṇa's prasāda sustains it. Killing and being killed are categories that apply only within the domain of māyā-body, which is itself Kṛṣṇa's līlā. The tone is imperative: recognize this and act in surrender.
- Śrīdharabhakti
Arjuna's grief had two roots: sorrow at the separation from Bhīṣma and others, and distress at his own role as killer. The first grief has been addressed by showing the soul's deathlessness; this verse addresses the second — ātman has neither kartṛtva (agency) nor karmatva (patient-hood) in relation to killing, and therefore no guilt attaches to the warrior who fights in righteous battle.
divergence: Śrīdhara is the most pastorally explicit: his bhāṣya traces both griefs and resolves both. His commentary is pedagogically structured (grief 1 → grief 2), and the devotional register colors his reading — right action in war becomes compatible with bhakti once agency is properly located away from the ātman.
- Madhusūdanaadvaita-bhakti
Even if Arjuna's grief at loss has been answered, the objection remains: where there is no grief, there is not necessarily no sin — one may kill a despised brahmin without grief yet still incur pāpa (demerit). To forestall this, Bhagavān cites the Kaṭha-śruti (hantā cen manyate hantuṃ hataś cen manyate hatam): the tārkika (logician) who grants ātman-agency and the cārvāka who grants ātman-destructibility are both named as the two mistaken parties (ubhau tau na vijānītaḥ), for ātman is neither doer nor done-to.
divergence: Madhusūdana uniquely names the two philosophical opponents — tārkika (Nyāya-Vaiśeṣika school granting jīva-kartṛtva) and Cārvāka (materialist school admitting ātman-nāśa) — and shows that the Kaṭha citation demolishes both simultaneously. The synthesis of Advaita jñāna with Kṛṣṇa-devotion is visible in his framing: Bhagavān is the active teacher deploying śruti as weapon, not merely a theoretical voice.
