eṣa tasyāśramaḥ puṇyo ya eṣo'gre virājate |
kṣānta uṣyātra ṣaḍrātraṃ prāpnoti sugatiṃ naraḥ || 18 ||

"Lomasa said, The lotus-eyed king did all that exactly in the way prescribed to him. And when his sins were worked off, he was set free together with the priest. O king! Fond of the priest as he was, he won all those blessings to which he had entitled himself by his meritorious acts and shared everything with the family priest. This is his hermitage which looketh lovely before our eyes. Any one would attain the blessed regions, if he should spend six nights here controlling his passions. O king of kings! O leader of the tribe of Kurus! Here, free from excitement and self-controlled, we must spend six nights. Be thou ready therefor.'"
