One who thinks this Self is a slayer and one who thinks it is slain — both of these do not know. This Self neither slays nor is slain.
Synthesis
This verse and the next (2.20) form the philosophical pinnacle of the atma-jnana section. The Self is beyond the categories of agent and patient — it is neither a slayer nor capable of being slain. This is not a dismissal of moral concern about killing but a precise metaphysical statement: the categories of action (killing) and suffering (being killed) belong to the realm of bodies, not to the Self. Shankara reads this as the clearest possible refutation of the empirical self's claim to ultimate agency — what 'kills' is the body-mind complex, not the eternal witness. The Bhakti tradition uses this verse carefully: it does not mean one may kill carelessly, but that in righteous battle undertaken as God's instrument, the devotee-warrior is not the ultimate agent. Tilak's reading is militantly practical: soldiers paralyzed by the thought that they are killers are confused about the nature of the Self. Vivekananda extended this to a universal principle: we are not the doers of any action in the ultimate sense — and this recognition frees us from both pride and guilt.

Shankara explains that both — the one who considers the Atman to be the killer and the one who considers it capable of being killed — are equally ignorant. The Atman is pure consciousness, not an agent. Agency (kartritva) and patienthood (bhoktritva) belong to the empirical self conditioned by avidya. The real Self is the witness — the unchanging awareness in which action and suffering appear, but which itself neither acts nor suffers.

Excessive guilt and excessive pride both rest on the same illusion — that you are the ultimate author of what happens. Recognizing that agency is more complex and distributed can free you from both self-punishment and self-inflation.
