Svetadvipa; There is a Vaikunthaloka covered with water in the material world, which is an inestimable distance away in the direction of the [[Wikipedia:Makara (Hindu mythology)Makara Rashi (Shravana Zodiac) or the Capricorn Constellation, and on that planet, is a place called Vedavati, where Vishnu resides.
Another planetary system known as Vishnuloka, also an inestimable distance away and again in the direction of the Makara Rashi (Shravana Zodiac) or the Capricorn Constellation, is situated above Satyaloka (see: Vaikuntha) and that is where Sankarshana is present.
On the island known as Svetadvipa there is an ocean of milk, and in the midst of that ocean, is a place called Airavati-pura where Aniruddha lies on Ananta.
Cosmologically the Dvipas and Sagaras depict the entire Cosmos, though in Cartiography (or Cosmography), all the Dvipas and Sagaras are shown to lie in the Southern Hemisphere. In some of the satvata-tantras there is a description of the nine varshas and the predominating Deity worshiped in each:
Paramatma, the Supersoul in the heart of everyone through whom all Avatars come to material universe, is lying on that Milk ocean. So Paramatma is Ksirodakasayi Vishnu)] - who is in every atom and heart of all souls in 8 400 000 kinds of material bodies, with two souls in each heart called jivaatma and Paramatma).
