Mbh 3.84.1j

There in that tirtha, O bull of the Bharata race, it is well known that ten millions of tirthas exist together. A wicked Asura in the shape of a tortoise had, O foremost of monarchs, been carrying it away when the powerful Vishnu recovered it from him. There in that tirtha should one perform his ablutions, for by this he acquireth the merit of the Pundarika sacrifice and ascendeth also to the region of Vishnu. Then, O best of kings, should one proceed to the place of Narayana, where, O Bharata, Narayana is ever present and dwelleth for aye. There the gods with Brahma at their head, Rishis endued with wealth of asceticism, the Adityas, the Vasus, and the Rudras, all adore Janardana, in that tirtha, and Vishnu of wonderful deeds hath become known as Salagrama. Approaching the eternal Vishnu, that lord of the three worlds, that giver of boons, one obtaineth the merit of the horse-sacrifice, and goeth to the region of Vishnu. There in that place, O virtuous one, is a well, capable of destroying every sin. The four seas are ever present in that well. He that bathes in it, O king, will have immunity from misfortune. Beholding (the image of) the boon-giving, eternal, and fierce Mahadeva who is there, one shineth, O king, like the moon emerged from the cloud. Bathing then in Jatismara, with pure mind and subdued senses, one acquireth, without doubt, the recollections of his former life. Proceeding then to Maheswarapura, and worshipping the god having the bull for his mark, fasting the while, one obtaineth, without doubt, the fruition of all his desires. Repairing then to Vamana that destroys every sin, and beholding the god Hari, one acquireth exemption from every misfortune. One should next go to the asylum of Kusika that is capable of removing every sin. Repairing then to the river Kausika that cleanseth from even great sins, one should bathe in it. By this one obtaineth the merit of Rajasuya sacrifice.
