The Earth is situated in the middle of the 'fourteen planes of existence', of which 'Brahmaloka' is the highest plane.
But on the earth, atop the Mountain Meru, there is a city of Brahma, called 'Shatakaumbhi', which resembles a mountain of gold. Surrounding it are the citadels of the various 'Lokapalas', namely, Indra, Agni, Yama, Nirruti, Varuna, Vayu, Kubera and Ishana. This solves the problem of how can there be Lokapalas for the universe, because these 'Lokapalas' are now confined to 'Bhuloka'. Surrounding these cities are the various residences of devas and asuras.
The question is, are all these different cities from the actual 'Lokas' of the Devas?
Like do we have two Brahmas, two Indras, Agnis and so on, including double the number of devas and asuras per city?
OR are all these portals to the various other planes of existence?
