Mbh 3.71.1a

“Vrihadaswa continued, ‘Having heard the words of Sudeva king Rituparna, soothing Vahuka with gentle words, said, ‘O Vahuka, thou art well-skilled in training and guiding horses. If it pleases thee, I intend to go to Damayanti’s Swayamvara in course of a single day.’ Thus addressed, O son of Kunti, by that king, Nala felt his heart to be bursting in grief. And the high-souled king seemed to burn in sorrow. And he thought within himself, ‘Perhaps Damayanti in doing this is blinded by sorrow. Or, perhaps, she hath conceived this magnificent scheme for my sake. Alas, cruel is the deed that the innocent princess of Vidarbha intends to do, having been deceived by my sinful and low self of little sense. It is seen in the world that the nature of woman is inconstant. My offence also hath been great; perhaps she is acting so, because she hath no longer any love for me owing to my separation from her. Indeed, that girl of slender waist, afflicted with grief on my account and with despair, will not certainly do anything of the kind, when especially, she is the mother of offspring (by me). However whether this is true or false, I shall ascertain with certitude by going thither. I will, therefore, accomplish Rituparna’s and my own purpose also.’ Having resolved thus in his mind, Vahuka, with his heart in sorrow, spake unto king Rituparna, with joined hands, saying, ‘O monarch, I bow to thy behest, and, O tiger among men, I will go to the city of the Vidarbhas in a single day. O king!’ Then, O monarch, at the command of the royal son of Bhangasura, Vahuka went to the stables and began to examine the horses.
