One should next proceed to the place called Mayuravata, consecrated to Mahadeva of high intelligence. Beholding there the god, bowing down to him and walking round the spot, one acquireth, O Bharata, the Ganapatya status. Bathing in Ganga at that tirtha, one is cleansed of all his sins. Then, O king, should one proceed to Prayaga, whose praises have been sung by Rishis and where dwell the gods with Brahma at their head, the Directions with their presiding deities, the Lokapalas, the Siddhas, the Pitris adored by the worlds, the great Rishis-Sanatkumara and others, stainless Brahmarshis--Angiras and others,--the Nagas, the Suparnas, the Siddhas, the Snakes, the Rivers, the Seas, the Gandharvas, the Apsaras, and the Lord Hari with Prajapati. There in that tirtha are three fiery caverns between which the Ganga, that foremost of tirthas, rolleth rapidly. There in that region also the world-purifying daughter of the sun, Yamuna, celebrated over the three worlds, uniteth with the Ganga. The country between the Ganga and the Yamuna is regarded as the mons veneris of the world, and Prayaga as the foremost point of that region. The tirthas Prayaga, Pratisthana, Kamvala, Aswatara and Bhogavati are the sacrificial platforms of the Creator. There in those places, O foremost of warriors, the Vedas and the Sacrifices, in embodied forms, and the Rishis endued with wealth of asceticism, adore Brahma, and there the gods and rulers of territories also celebrate their sacrifices.
