The pilgrim should next, O virtuous one, proceed to the peak of the great goddess Gauri, famed over the three worlds. Ascending it, O best of men, one should approach Stana-Kunda. By touching the waters of Stana-Kunda, a person obtaineth the merit of the Vajapeya sacrifice. Bathing in that tirtha and worshipping the gods and Pitris, one acquireth the merit of the horse-sacrifice and also ascendeth to the region of Indra. Arriving next at the well of Tamraruna, that is frequented by the gods, one acquireth, O lord of men, the merit that attaches to human sacrifice. Bathing next at the confluence of the Kirtika with the Kausiki and the Aruna, and fasting there for three nights a man of learning is cleansed of all his sins.
