Then, O lord of men, the pilgrim should proceed to the tirtha called Kuvjamraka. By this he obtaineth the merit of giving away a thousand kine, and heaven also. Then, O king, the pilgrim should go to the Arundhativata. Proceeding thither with concentrated soul and practising the Brahmacharya vows, one that batheth in Samudraka and fasteth for three nights, obtaineth the merit of the horse-sacrifice and of giving away a thousand kine, and also rescueth his race. One should next proceed to Brahmavarta, with concentrated soul and practising the Brahmacharya vows. By this, one obtaineth the merit of the horse-sacrifice, and goeth to the region of Soma. The man that proceedeth to the Yamuna-prabhava, (the source of the Yamuna) and batheth there, obtaineth the merit of the horse-sacrifice and is worshipped in heaven. Arriving at Darvisankramana, that tirtha which is worshipped of the three worlds, a person obtaineth the merit of the horse-sacrifice and goeth to heaven. Repairing next to Sindhu-prabhava (the source of the Indus) which is worshipped by Siddhas and Gandharvas, and staying there for five nights, one obtaineth the merit of giving away gold in abundance. Proceeding next to the inaccessible tirtha called Vedi, one obtaineth the merit of the horse-sacrifice and ascendeth to heaven. Then, O Bharata, should one proceed to Rishikulya and Vasishtha. By visiting the latter, all orders attain to Brahmanhood.
