Mbh 11.27.1a

Vaishampayana said, "Arrived at the auspicious Ganga full of sacred water, containing many lakes, adorned with high banks and broad shores, and having a vast bed, they cast off their ornaments, upper garments, and belts and girdles. The Kuru ladies, crying and afflicted with great grief, offered oblations of water unto their sires and grandsons and brothers and kinsmen and sons and reverend seniors and husbands. Conversant with duties, they also performed the water-rite in honour of their friends. While those wives of heroes were performing this rite in honour of their heroic lords, the access to the stream became easy, although the paths (made by the tread of many feet) disappeared afterwards. The shores of the stream, though crowded with those spouses of heroes, looked as broad as the ocean and presented a spectacle of sorrow and cheerlessness. Then Kunti, O king, in a sudden paroxysm of grief, weepingly addressed her sons in these soft words, 'That hero and great bowman, that leader of leaders of car-divisions, that warrior distinguished by every mark of heroism, who hath been slain by Arjuna in battle, that warrior whom, ye sons of Pandu, ye took forth, Suta's child born of Radha, that hero who shone in the midst of his forces like the lord Surya himself, who battled with all of you and your followers, who looked resplendent as he commanded the vast force of the Duryodhana, who had no equal on earth for energy, that hero who preferred glory to life, that unretiring warrior firm in truth and never fatigued with exertion, was your eldest brother. Offer oblations of water unto that eldest brother of yours who was born of me by the god of day. That hero was born with a pair of earrings and clad in armour, and resembled Surya himself in splendour!' Hearing these painful words of their mother, the Pandavas began to express their grief for Karna. Indeed, they became more afflicted than ever.
