Mbh 13.25.3b

One who gives oblations of water unto one's Pitris at Saptaganga and Triganga and Indramarga, obtains ambrosia for food, if one has still to undergo rebirth. The man who in a pure state of body and mind attends to his daily Agnihotra and observes a fast for one month and then bathes in Mahasrama, is sure to attain success in one month. By bathing, after a fast of three days and purifying the mind of all evil passions, in the large lake of Bhrigu Kunda, one becomes cleansed of even the sin of Brahmanicide. By bathing in Kanyakupa and performing one's ablutions in Valaka, one acquires great fame among even the deities and shines in glory. Bathing in Devika and the lake known by the name of Sundarika as also in the Tirtha called Aswini, one acquires, in one's next life, great beauty of form. By fasting for a fortnight and bathing in Mahaganga and Krittikangaraka, one becomes cleansed of all one's sins and ascends to heaven. Bathing in Vaimanika and Kinkinika, one acquires the power of repairing everywhere at will and becomes an object of great respect in the celestial region of the Apsaras.[234] If a person, subduing his wrath and observing the vow of Brahmacharyya for three days, bathes in the river Vipasa at the retreat called Kalika, he is sure to succeed in transcending the obligation of rebirth. Bathing in the asylum that is sacred to the Krittakas and offering oblations of water to the Pitris, and then gratifying Mahadeva, one becomes pure in body and mind and ascends to heaven. If one, observing a fast for three days with a purified body and mind, bathes in Mahapura, one becomes freed from the fear of all mobile and immobile animals as also of all animals having two feet. By bathing in the Devadaru forest and offering oblations of water to the Pitris and dwelling there for seven nights with a pure body and mind, one attains to the region of the deities on departing from this world.
