"Meanwhile the Rishi reflected, 'The prince is young. Having obtained an excellent pair of animals, he is sporting with it in joy without returning it to me. Alas, what a pity it is!' And reflecting in this strain, the Rishi said unto a disciple of his, after the expiration of a month, 'Go, O Atreya, and say to the king that if he has done with the Vami steeds, he should return them unto thy preceptor.' And the disciple Atreya, thereupon, repairing to the king, spoke unto him as instructed, and the king replied saying, 'This pair of steeds deserves to be owned by kings. The Brahmanas do not deserve to possess jewels of such value. What business have Brahmanas with horses? Return thou contentedly!' And Atreya, thus addressed by the king, returned and told his preceptor all that had happened, and hearing this sad intelligence, Vamadeva's heart was filled with wrath, and repairing in person to the king he asked him for his steeds, and the king refused to give the Rishi what the latter asked, and Vamadeva said, 'O lord of earth, give me thou my Vami horses. By them hast thou accomplished a task which was almost incapable of being accomplished by thee. By transgressing the practices of Brahmanas and Kshatriyas, subject not thyself, O king, to death by means of the terrible noose of Varuna.' And hearing this, the king answered, 'O Vamadeva, this couple of excellent well-trained, and docile bulls are fit animals for Brahmanas.
