Matsyapurana 111.11

111.11

yasmiñjuhvansvakaṃ pāpaṃ narakaṃ ca na paśyati
evaṃ brahmā ca viṣṇuśca prayāge sa maheśvaraḥ //

Brahmâ, Viṣṇu, Śiva, the seven Dvîpas, the ocean and the mountains, safely there dwell, and besides them other Devas also dwell there till the end of the world.—12-13.

The circumference of Prayâga is five yojanas; owing to the absence of sin, Brahmâ resides towards the northern portion of the tîrtha to guard it, Viṣṇu stands personified in Veṇîmâdhava, and Śiva has fixed Himself in the form of the sacred banyan tree. Besides them, the Devas, the Gandharvâs, the ascetics and the seers guard the boundary of the holy place after driving away sin from there. It is the place where a man after getting rid of his sins does not see hell at all.—8-11.
