And the two sons of the Nāga king pursuing pleasure day by day, played[25] with Ṛtadhvaja like the immortals. But one day the Nāga king, being intoxicated, spoke to his sons, “Why indeed do ye not do as I told you before? The king’s son is your benefactor in my opinion; why do ye not confer a benefit on him, the pride-inspirer? Thereupon they both, being thus admonished by their kindly-affectioned father, went to their friend’s city, and enjoyed themselves with the wise prince. Then both, after having held some other talk with Kuvalayāśva, invited him respectfully to come to their house. The king’s son said to them, “Is not this your house? Whatever is mine, riches, carriages, garments, &c., that is indeed yours. But whatever ye desire should he given you, riches or jewels, let that be given you, O young dvijas, if ye have friendly regard for me. Am I cheated by such a cruel fate as this, that ye do not evince any sense of ownership in my house F If ye must do me kindness, if I am to receive favour from you, then consider my wealth and home as your own. Whatever is yours is mine, mine is your own. Believe ye this in truth. My life has gone out into you. Never again must ye speak of separate property, O virtuous dvijas: since ye are devoted to my favour, I have adjured you by my heart affectionately.”

Thereupon both the young Nāgas, their faces beaming with affection, replied to the king’s son, somewhat feigning anger. “Ṛtadhvaja, without doubt, we must not think in our mind in this matter otherwise than thou hast now spoken. But our high-souled father has himself repeatedly said this—‘I wish to see that Kuvalayāśva.’” Thereon Kuvalayāśva rising from his seat of honour, prostrated himself on the ground, saying, “Be it as your dear father says.”
