piṇḍodakapradānena naraḥ karmaṇyavasthitaḥ //

The king said to her. “Why dost thou deal thus, O foolish one, with the temperament of my child, by giving him a michievous education as thou didst before to my other sons. If thou shouldest do what pleases me, if my word should be accepted, then restrain this son within the path of activity. So the path of action will not lead to utter destruction, O lady; and so the piṇḍa offering to the pitṛs will not cease, O virtuous one. The pitṛs dwell in the Devaloka, they are also born as brutes, they become men likewise, and they reside within the class of elements. By offering the piṇḍa and water a man, busied in the ceremonies, ever nourishes them, O fine-browed one, both the righteous and the unrighteous, those worn out with hunger, those harassed by thirst; he nourishes the gods likewise and guests. The gods, mankind, the pitṛs, departed spirits, goblins, and guhyakas, birds, worms and insects live upon man indeed. Therefore, O slender-limbed, cause my son to acquire thoroughly the whole duty of kṣatriyas, as regards this life and life in the next world.”
