yathā kuntī tathā mādrī viśeṣo nāsti me tayoḥ |
mātṛbhyāṃ samamicchāmi nakulo yakṣa jīvatu || 73 ||

Therefore, let Nakula, O Yaksha, revive! Let men know that the king is always virtuous! I will never depart from my duty. Let Nakula, therefore, revive! My father had two wives, Kunti and Madri. Let both of them have children. This is what I wish. As Kunti is to me, so also is Madri. There is no difference between them in my eye. I desire to act equally towards my mothers. Therefore, let Nakula live?' The Yaksha said,--'Since abstention from injury is regarded by thee as higher than both profit and pleasure, therefore, let all thy brothers live, O bull of Bharata race!"
