The Mahabharata of Krishna-Dwaipayana Vyasa…
“ I know this, O Bhima, viz., that he hath gone, but he hath not yet returned. Dark in complexion, youthful in years, of curly locks, exceedingly handsome mighty car-warrior, of broad chest and long arms, possessed of the tread of an infuriated elephant, of eyes of the colour of burnished copper and like those a chakra, that brother of thine enhances the fears of foes. Blessed be thou, even this is the cause of my grief, O chastiser of foes! For Arjuna’s sake, O thou of mighty arms, as also for the sake of Satwata, my grief increaseth like a blazing fire fed with libations of clarified butter. ”
