Mbh 13.25.3c

Bathing in the waterfalls at Sarastamva and Kusastambha and Dronasarmapada, one is sure to attain to the region of the Apsaras where one is waited upon with dutiful services by those superhuman beings. If one, observing a fast, bathes at Chitrakuta and Janasthana and the waters of Mandakini, one is sure to be united with prosperity that is royal.[235] By repairing to the retreat that is known by the name of Samya and residing there for a fortnight and bathing in the sacred water that exists there, one acquires the power of disappearing at will (and enjoy the happiness that has been ordained for the Gandharvas). Repairing to the tirtha known by the name of Kausiki and residing there with a pure heart and abstaining from all food and drink for three days, one acquires the power of dwelling (in one's next life) in the happy region of the Gandharvas. Bathing in the delightful tirtha that goes by the name of Gandhataraka and residing there for one month, abstaining all the while from food and drink, one acquires the power of disappearing at pleasure and, then one and twenty days, of ascending to heaven. He that bathes in the lake known by the name of Matanga is sure to attain to success in one night. He that bathes in Analamva or in eternal Andhaka, or in Naimisha, or the tirtha called Swarga, and offers oblations of water to the Pitris, subduing his senses the while, acquires the merit of a human sacrifice.[236] Bathing in Ganga hrada and the tirtha known by the name of Utpalavana and daily offering oblations of water there for a full month to the Pitris, one acquires the merit of a Horse-sacrifice. Bathing in the confluence of the Ganga and the Yamuna as also at the tirtha in the Kalanjara mountains and offering every day oblations of water to the Pitris for a full month, one acquires the merit that attaches to ten Horse-sacrifices. Bathing in the Shashthi lake one acquires merit much greater than what is attached to the gift of food.
