niṣadheṣu mahīpālo vīrasena iti sma ha |
tasya putro'bhavannāmnā nalo dharmārthadarśivān || 39 ||

"Vrihadaswa said, 'O king, O thou that never fallest off, listen attentively with thy brothers, I will narrate the history of a prince more miserable than thyself. There was a celebrated king among the Nishadhas, named Virasena. He had a son named Nala, versed in (the knowledge of) virtue and wealth. It hath been heard by us that, that king was deceitfully defeated by Pushkara, and afflicted with calamity, he dwelt in the woods with his spouse. And, O king, while he was living in the forest, he had neither slaves nor cars, neither brother nor friends with him. But thou art surrounded by thy heroic brothers like unto the celestials, and also by foremost regenerate ones like unto Brahma himself. Therefore, it behoveth thee not to grieve.'
