O Pandava, Indra and Vaisravana preside over this point graced with woods and forests and mountains. And, O child, the intelligent sages versed in every duty, say, that this (region) is the abode of Indra and king Vaisravana. And the twice-born ones, and the sages versed in the duties, and the Sidhas, and the Sadhyas, and the celestials pay their adorations unto the Sun as he riseth from this point. And that lord of all living beings, king Yama, conversant with duty, presideth over yonder southern region whither come the spirits of the departed. And this is Sanyamana, the abode of the lord of departed spirits, sacred, and wonderful to behold, and crowned with prime prosperity. And the intelligent ones call that monarch of mountains (by the name of) Asta. Having, O king, arrived at this, the Sun ever abideth by the truth. And king Varuna protects all creatures, abiding in this king of mountains, and also in the vast deep.
