According to Puranic cosmography, the world is divided into seven concentric island continents ("sapta-dvipa vasumati") separated by the seven encircling oceans, each double the size of the preceding one (going out from within). The seven continents of the Puranas are stated as Jambudvipa, Plaksadvipa, Salmalidvipa, Kusadvipa, Krouncadvipa, Sakadvipa, and Pushkaradvipa. Seven intermediate oceans consist of salt-water, sugarcane juice, wine, ghee, yogurt, milk and water respectively. The mountain range called Lokaloka, meaning "world-no-world", stretches across this final sea, delineating the known world from the dark void.
