Believing yourself to be conversant with morality, you are observing it in a way which but indicates your ignorance of it. You believe yourself to be virtuous but you know not, O Partha, that it is a sin to slay living beings.
अविज्ञानाद् भवान् यच्च धर्म रक्षति धर्मवित्। प्राणिनां त्वं वधं पार्थ धार्मिको नावबुध्यसे॥
