Bhagavad Gita · Chapter 2: The Path of Understanding
Bhagavad Gita 2.21
वेदाविनाशिनं नित्यं य एनमजमव्ययम् ।
कथं स पुरुषः पार्थ कं घातयति हन्ति कम् ॥
vedāvināśinaṃ nityaṃ ya enamajamavyayam | kathaṃ sa puruṣaḥ pārtha kaṃ ghātayati hanti kam ||
One who knows this self to be indestructible, eternal, unborn, and unchanging: how, Arjuna, can that person kill anyone, or cause anyone to be killed?
Modern context
Krishna puts the conclusion as a question so that Arjuna has to answer it himself: if you truly knew the self to be indestructible, in what sense could you destroy anyone? Good teachers often end an argument with a question, because a conclusion we reach ourselves stays with us.
