The man who, repairing to the excellent tirtha called Vidya, batheth there in the evening, obtaineth proficiency in every kind of knowledge. 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.

Going next to the tirtha called Sundarika, worshipped by the Siddhas, one obtaineth personal beauty as witnessed by the ancients.

One should repair next to the sacred Naimisha, worshipped by the Siddhas.
