Mbh 3.84.1e

One should next reside for one night at Mahasrama capable of destroying every sin, taking a single meal. By this, one obtains many auspicious regions, and delivers ten preceding and ten succeeding generations of his race. Dwelling next for a month of Mahalaya, and fasting there for three nights, one’s soul is cleansed of all sins and one acquires the merit of giving away gold in abundance. Proceeding next to Vetasika worshipped by the Grandsire, one obtaineth the merit of the horse-sacrifice and the state of Usanas. Going next to the tirtha called Sundarika, worshipped by the Siddhas, one obtaineth personal beauty as witnessed by the ancients. Proceeding next to Brahmani with subdued senses and observing the Brahmacharya vow, a person ascendeth to the region of Brahma on a lotus-hued car. One should repair next to the sacred Naimisha, worshipped by the Siddhas. There dwelleth for aye Brahma with the gods. By only purposing to go to Naimisha, half one’s sins are destroyed; by entering it, one is cleansed of all his sins. The pilgrim of subdued senses should stay at Naimisha for a month; for, O Bharata, all the tirthas of the earth are at Naimisha. Bathing there, with restrained senses and regulated fare, one obtains, O Bharata, the merit of the cow-sacrifice, and also sanctifies, O best of the Bharatas, his race for seven generations both upwards and downwards. He who renounceth his life at Naimisha by fasting, enjoyeth happiness in the heavenly regions. Even this is the opinion of the wise. O foremost of kings, Naimisha is ever sacred and holy. Proceeding next to Gangodbheda and fasting there for three nights, a man obtaineth the merit of the Vajapeya sacrifice, and becometh like unto Brahma himself. Journeying to the Saraswati, one should offer oblations unto the gods and the Pitris. By this, one certainly enjoyeth bliss in the regions called Saraswata. Then should one wend to Vahuda, with subdued soul and observing the Brahmacharya vow.
