Vaisampayana said, “O represser of foes, hearing these words of the intelligent monkey-chief, the heroic Bhima answered, ‘Who art thou? And why also hast thou assumed the shape of a monkey? It is a Kshatriya—one of a race next to the Brahmanas—that asketh thee. And he belongeth to the Kuru race and the lunar stock, and was borne by Kunti in her womb, and is one of the sons of Pandu, and is the off spring of the wind-god, and is known by the name of Bhimasena.’
In plain words: Bhima asks who this being really is and why he looks like a monkey. Then he proudly introduces himself as a warrior of the Kuru family, son of Kunti and Pandu, born of the wind-god, named Bhimasena.
