So the God of Fire has got his burning power and is residing in the
bellies of the Devas, the Asuras, men and all other beings and
penetrating their bellies, is satisfying all. Yama, the King of
Dharma, by Thy appointment, is the Lord of the southern quarters, is
presiding over the Pitris and being the witness of all the actions of
the Jivâs, is awarding duly to them the fruits thereof.
Nairrita, the Lord of the Raksasas, the witness of all the actions of
all the beings, by Thy commandment, is the destroyer of all the
obstacles of the devotees that take refuge unto thee, though he is a
Yaksa. The Varuna Deva, by Thy order, has become duly the Lord of the
waters, and the Regent of the Loka (Dikpâla). The Vâyu, the Life of
all, the carrier of the smell, has become by Thy order Lokâpâla and
the Guru of the universe. Kuvera, obedient to Thy order, has become
the Lord of the Yaksas and the Kinnaras and is holding a respectful
position like other Lokapâlas
