structure of universe
Structure of universe from Brahma vaivarta purana:
.
There was a ball of light in the beginning, after dissolution, the lustre of which resembled tens of millions of suns… All the three worlds are enclosed in this ball of light quite pleasantly.
Goloka is located above the three worlds which is eternal like the Lord himself… It exists in the form of a globe. It is quite illustrious and is studded with gems. The yogis cannot visualise it even in a dream, while the Vaisnavas not only visuialise it but echieve it.
…
Below Goloka and at a distance of 500 000 000 yojanas, Vaikuntha is located to its south. Sivaloka to located to its west…
Vaikuntha is located in a cirkular way covering an area of 10 000 000 yojanas…
To the west of Vaikuntha is Sivaloka, which is spread over an area of 10 000 000 yojanas.
