'There on that mountain (Kunjara) stands a city called Bhogavati, which is the abode of serpents. It has wide corridors. Guarded on all sides, it is unassailable since it is protected by venomous serpents with sharp fangs. The wise serpent king Vasuki resides there. (Bhogavati is the replica of the city of the same name in Patala, the sixth subterranean region)
