tvayā dāyādavānasmi tvaṃ me vaṃśakaraḥ sutaḥ |
pauravo vaṃśa iti te khyātiṃ loke gamiṣyati || 45 ||

[paragraph continues] On the other hand, like sacrificial butter poured into the fire, they flame up with indulgence. Even if one enjoyed the whole Earth with its wealth, diamonds and gold, animals and women, one may not yet be satiated. It is only when man doth not commit any sin in respect of any living thing, in thought, deed, or speech, it is then that he attaineth to purity as that of Brahman. When one feareth nothing, when one is not feared by anything, when one wisheth for nothing, when one injureth nothing, it is then that one attaineth to the purity of Brahman.' The wise monarch seeing this and satisfied that one's appetites are never satiated, set his mind at rest by meditation, and took back from his son his own decrepitude. And giving him back his youth, though his own appetites were unsatiated, and installing him on the throne, he spoke unto Puru thus, 'Thou art my true heir, thou art my true son by whom my race is to be continued. In the world shall my race be known by thy name.'
