Mbh 3.85.1a

“Pulastya said, ‘Arriving next at the excellent tirtha called Samvedya in the evening, and touching its waters, one surely obtaineth knowledge. Created a tirtha in days of yore by Rama’s energy, he that proceedeth to Lauhitya obtaineth the merit of giving away gold in abundance. Proceeding next to the river Karatoya, and fasting there for three nights, a man acquireth the merit of the horse-sacrifice. Even this is the injunction of the Creator himself. It hath been said by the wise, O king, that if a person goeth to the spot where the Ganga mingleth with the sea, he reapeth merit which is ten times that of the horse-sacrifice. Crossing over to the opposite bank of the Ganga, he that batheth there having resided for three nights is, O king, cleansed from all his sins. One should next proceed to the Vaitarani capable of destroying every sin. Arriving next at the tirtha named Viraja one shineth like the moon, and sanctifying his race rescueth it and is himself cleansed of all his sins. He that bathes in Viraja further reapeth the merit of giving away a thousand kine besides sanctifying his line. Residing with purity at the confluence of the Sona and the Jyotirathi, and offering oblations of water to the gods and the Pitris, a man reapeth the merit of the Agnishtoma sacrifice. Touching next the waters of the Vansagulma constituting the sources of both the Sona and the Narmada, one obtaineth the merit of the horse-sacrifice. Sojourning next to the tirtha called Rishabha in Kosala, O lord of men, and fasting there for three nights one earneth the merit of the Vajapeya sacrifice, and of the gift of a thousand kine, and also delivereth his race. Arriving at Kosala, a man should bathe in the tirtha named Kala. By this one surely obtaineth the merit of giving away one and ten bulls. By bathing in Pushpavati and fasting there, O king, for three nights one sanctifieth his own race, besides earning the merit of the gift of a thousand kine.
