Bhagavad Gita 2.21
वेदाविनाशिनं नित्यं य एनमजमव्ययम् । कथं स पुरुषः पार्थ कं घातयति हन्ति कम् ॥
vedāvināśinaṃ nityaṃ ya enam ajam avyayam | kathaṃ sa puruṣaḥ pārtha kaṃ ghātayati hanti kam ||
Translation
O son of Pṛthā, how can the one who knows this to be indestructible, eternal, unborn, and unchanging — how can such a one slay, or cause to be slain, whom?
Reflection
What cathedral of feeling have you built on a foundation that does not hold?
Read this verse in its chapter: Chapter Two
A rhetorical question with no rhetorical softness. Kaṃ ghātayati hanti kam. Whom does he cause to slay; whom does he slay. The doer and the done-to have both dissolved. Krishna is not saying killing is fine. He is saying that the act, looked at clearly, does not have the metaphysical weight Arjuna has assigned to it. The verse is sharp. Arjuna built a cathedral of grief on a foundation that, on inspection, does not exist as he believed. The cathedral does not vanish; the foundation gets named.
