Mbh 5.119.1a

“Narada said, ‘Seeing Galava, Vinata’s son smilingly addressed him, saying, “By good luck it is, O Brahmana, that I behold thee successful.” Galava, however, hearing the words spoken by Garuda informed him that a fourth part of the task was still unfinished. Garuda then, that foremost of all speakers, said unto Galava, “Do not make any endeavour (to obtain the remaining two hundred), for it will not succeed. In days of yore, Richika sought at Kanyakuyja Gadhi’s daughter, Satyavati, for making her his wife. Thereupon Gadhi, O Galava, addressing the Rishi, said, ‘O holy one, let a thousand steeds of lunar brightness, each with one ear black of hue, be presented to me.’ Thus requested, Richika said, ‘So be it’. And then wending his way to the great mart of steeds (Aswatirtha) in Varuna’s abode, the Rishi obtained what he sought and gave them unto the king. Performing a sacrifice then of the name of Pundarika, that monarch gave away those steeds (as Dakshina) unto the Brahmanas. The three kings to whom thou hadst applied had purchased those horses from the Brahmanas, each to the number of two hundred. The remaining four hundred, O best of Brahmanas, while being transported over the river, were taken by the Vitasta.[17] Therefore, O Galava, thou canst never have that which is not to be had. Do thou then, O virtuous one, present unto Viswamitra this maiden as an equivalent for two hundred steeds, along with the six hundred thou hast already obtained. Thou wilt then, O best of Brahmanas, be freed from thy grief and crowned with success.” Galava then, saying, “So be it,” and taking with him both the maiden and the steeds, went with Garuda in his company unto Viswamitra. And arrived in his presence, Galava said, “Here are six hundred steeds of the kind demanded by thee. And this maiden is offered as an equivalent for the remaining two hundred. Let all these be accepted by thee. Upon this maiden have been begotten three virtuous sons by three royal sages.
