SB 1.8.1
suta uvaca
atha te samparetanam
svanam udakam icchatam
datum sakrsna gangayam
puraskrtya yayuh striyah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Suta Gosvami said: Thereafter the Pandavas, desiring to deliver water to the dead relatives who had desired it, went to the Ganges with Draupadi. The ladies walked in front.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
To date it is the custom in Hindu society to go to the Ganges or any other sacred river to take bath when death occurs in the family. Each of the family members pours out a potful of the Ganges water for the departed soul and walks in a procession, with the ladies in the front. The Pandavas also followed the rules more than five thousand years ago. Lord Krsna, being a cousin of the Pandavas, was also amongst the family members.
