Staggering with extremely burning throat having drunk the venomous poison- which came out while churning the sea- Lord Shiva was wandering with parching mouth in the quest of water. As he reached Gosaikunda, he pierced the trident into the earth from where spring of water has come out. His burning throat was cooled with the water and the place was thus called Gosaikunda and the flowing water came to be named as Trisuli, Trishulganga (holy river flowing out of trident). Lord Shiva is believed to have said himself that one who has a holy dip at this place, and offers dana (charity) can have the grace of Lord Shiva. It is located in Rasuwa district of Bagmati zone to the north of Kathmandu.
