Mbh 1.186.2a

“Vaisampayana said, ‘Then those tigers among men--those brothers--the five Pandavas, set out for Panchala to behold that country and Draupadi and the festivities (in view of her marriage). And those tigers among men--those oppressors of all enemies--in going along with their mother, saw on the way numerous Brahmanas proceeding together. And those Brahmanas who were all Brahmacharis beholding the Pandavas, O king, asked them, ‘Where are ye going to? Whence also are ye come?’ And Yudhishthira replied unto them, saying, ‘Ye bulls among Brahmanas, know ye that we are uterine brothers proceeding together with our mother. We are coming even from Ekachakra.’ The Brahmanas then said, ‘Go ye this very day to the abode of Drupada in the country of the Panchalas. A great Swayamvara takes place there, on which a large sum of money will be spent. We also are proceeding thither. Let us all go together. Extraordinary festivities will take place (in Drupada’s abode). The illustrious Yajnasena, otherwise called Drupada, had a daughter risen from the centre of the sacrificial altar. Of eyes like lotus-petals and of faultless features endued with youth and intelligence, she is extremely beautiful. And the slender-waisted Draupadi of every feature perfectly faultless, and whose body emitteth a fragrance like unto that of the blue lotus for two full miles around, is the sister of the strong-armed Dhrishtadyumna gifted with great prowess--the (would-be) slayer of Drona--who was born with natural mail and sword and bow and arrows from the blazing fire, himself like unto the second Fire. And that daughter of Yajnasena will select a husband from among the invited princes. And we are repairing thither to behold her and the festivities on the occasion, like unto the festivities of heaven.
