'Having come before the king that afflicter of foes, Sahadeva answered in accents deep as the roar of the cloud, 'I am a Vaisya, Arishtanemi by name. I was employed as a cowherd in the service of those bulls of the Kuru race, the sons of Pandu. O foremost of men, I intend now to live beside thee, for I do not know where those lions among kings, the sons of Pritha, are. I cannot live without service, and, O king, I do not like to enter into the service of anyone else save thee.'
