Verse
पापमेवाश्रयेदस्मान् हत्वैतानाततायिनः ।तस्मान्नार्हा वयं हन्तुं धार्तराष्ट्रान्स्वबान्धवान् ।स्वजनं हि कथं हत्वा सुखिनः स्याम माधव ॥
Sin will take hold of us in slaying them. though they are the aggressors. So it is not fit that we kill the sons of Dhritarashtra, our kinsmen; indeed how may we be happy, O Madhava, killing our own people?
