There is no doubt they (the Pandavas) too are my sons, but Duryodhana has spring from my (own) body. Speaking partially how will you advise me to replace my own body for the sake of others?
असंशयं तेऽपि ममैव पुत्रा दुर्योधनस्तु मम देहात् प्रसूतः। स्वं वै देहं परहेतोस्त्यजोत को नु ब्रूयात् समतामन्ववेक्ष्य॥
