Proceeding next to Vimalasoka, with subdued soul and observing the Brahmacharya vow, and residing there for one night, one is adored in heaven. One should next proceed to the excellent Gopratra in the Sarayu, whence Rama, O king, with all his attendants and animals, renouncing his body, ascended to heaven in consequence of the efficacy of the tirtha alone. Bathing in that tirtha, O Bharata, one's soul, through Rama's grace, and by virtue of his own deeds, being cleansed of all sins, one becometh adored in heaven. O Bharata! Proceeding next, O son of the Kuru race, to the Rama-tirtha on the Gomati, and bathing there, one obtaineth the merit of the horse-sacrifice, and sanctifieth also his own race. There, O bull of the Bharata race, is another tirtha called Satasahasrika. Bathing there, with restrained senses and regulated diet, a person reapeth, O bull of Bharata race, the merit of giving away a thousand kine. Then should one, O king, go to the unrivalled tirtha called Bhartristhana. By this, a person obtaineth the merit of the horse-sacrifice. Bathing next in the tirtha called Koti, and worshipping [paragraph continues] Kartikeya, a man reapeth, O king, the merit of giving away a thousand kine, and acquireth great energy. Proceeding next to Varanasi, and worshipping the god having the bull for his mark, after a bath in the Kapilahrada, one obtaineth the merit of the Rajasuya sacrifice.
