Mbh 3.83.1f

Distant by a krosa, O king, to the east of Manusha there is a river celebrated by the name of Apaga that is restored to by the Siddhas. The man that offereth there the syamaka grain in honour of the gods and the Pitris acquireth great religious merit. And if one Brahmana is fed there, it becomes equivalent to feeding ten millions of Brahmanas. Having bathed in that tirtha and worshipped the gods and the Pitris and resided there for one night, a man obtaineth the merit of the Agnishtoma sacrifice. One should then repair, O king, to that excellent region of Brahma which, O Bharata, is known on earth by the name of Brahmodumvara. Bathing in the tank of the seven Rishis that is there, O bull among men, with pure mind and subdued soul, as also in the tirtha called Kedara of the high-souled Kapila, and beholding Brahma who is there, one’s soul being purified from all sins, one goeth to the abode of Brahma. Proceeding next to the inaccessible tirtha called Kedara of Kapila, and burning one’s sins there by ascetic penances, one acquireth the power of disappearance at will. One should next proceed, O king, to the celebrated tirtha called Saraka, and beholding Mahadeva there on the fourteenth day of the dark fortnight, one obtaineth all his wishes and goeth also into heaven. O son of the Kuru race, in Saraka and Rudrakoti as also in the well and the lakes that are there, thirty millions of tirthas are present. There in that tirtha, O chief of the Bharatas, is another called Ilaspada. Bathing there and worshipping the gods and the Pitris, one never sinketh into hell but obtaineth the fruit of the Vajapeya sacrifice. Repairing next to Kindana and Kinjapya, one acquireth, O Bharata, the merit of giving away in measureless abundance and the infinite recitation of prayers. Repairing next to the tirtha called Kalasi and bathing there devoutly and with the senses under control, a man obtaineth the fruit of the Agnishtoma sacrifice.
