tatrābhiṣekaṃ kurvīta pitṛdevārcane rataḥ |
aśvamedhamavāpnoti pitṛlokaṃ ca gacchati || 45 ||

O son of the Kuru race, a pilgrim by repairing then to the tirtha called Shankhini and bathing in the Devi-tirtha that is there, obtaineth high prowess. O king, one should then proceed to the tirtha called [paragraph continues] Tarandaka situated in the Saraswati and belonging to the illustrious chief of the Yakshas who is one of the gate-keepers (of Kuvera). O king, bathing there one obtaineth the fruit of the Agnishtoma sacrifice. O virtuous king, one should next repair to the tirtha called Brahmavarta. Bathing in Brahmavarta, one ascendeth to the abode of Brahma. O king, one should then repair to the excellent tirtha called Sutirtha. There the Pitris are ever present along with the gods. One should bathe there and worship the Pitris and the gods. By so doing, one obtaineth the merit of the horse-sacrifice and goeth (finally) into the region of the Pitris. It is for this, O virtuous one, that Sutirtha situate in Amvumati is regarded as so excellent. And, O thou best of the Bharata race, having bathed in the tirtha of Kasiswara, one becometh freed from all diseases and is adored in the abode of Brahma. There, in that tirtha, is another called Matri. One that bathes in Matri tirtha hath a large progeny and obtaineth, O king, great prosperity. One should next proceed with subdued sense and regulated diet to the tirtha called Shitavana.
