pṛthivyāṃ yāni tīrthāni antarikṣacarāṇi ca |
nadyo nadāstaḍāgāśca sarvaprasravaṇāni ca || 168 ||

It was here that Angiras, that ocean of ascetic austerities belonging to the Saraswata race, was born, Bathing in that tirtha, one obtaineth the merit of the horse-sacrifice, and without doubt, gaineth also residence in the legion of Saraswati. With subdued senses and leading a Brahmacharya mode of life, one should next proceed to Kanyasrama. Residing there for three nights, O king, with subdued senses and regulated diet, one obtaineth a hundred celestial damsels and goeth also to the abode of Brahma. One should next, O virtuous one, proceed to the tirtha called Sannihati. Sojourning thither the gods with Brahma at their head and Rishis endued with wealth of asceticism earn much virtue. Bathing in the Saraswati during a solar eclipse, one obtaineth the merit of a hundred horse-sacrifices, and any sacrifice that one may perform there produceth merit that is eternal. Whatever tirthas exist on earth or in the firmament, all the rivers, lakes, smaller lakes, springs, tanks, large and small, and spots sacred to particular gods, without doubt, all come, O tiger among men, month after month, and mingle with Sannihati, O king of men! And it is because that all other tirthas are united together here, that this tirtha is so called. Bathing there and drinking of its water, one becometh adored in heaven. Listen now, O king, to the merit acquired by that mortal who performeth a Sraddha on the day of the new moon during a solar eclipse.
