Krishna challenges Arjuna's logic by asking a rhetorical question. If a person truly knows (veda) that the soul is indestructible (avināśinaṃ) and immutable (avyayam), how can that person be a 'killer' (hanti) or cause someone else to be killed (ghātayati)? Since the soul cannot be killed, the very concept of 'murdering the soul' is a logical impossibility.
