At the navel of the inner-continent Ilavrta is the all-gold mount Meru, the king of all the mountains. It is as high as the extent of his dvipa. It forms the pericarp of the lotus in the form of the earth. It is thirty-two thousand yojanas in extent at the top, and sixteen thousand yojanas at its foot, and its root lies under the earth's surface to the same extent viz. sixteen thousand yojanas. (i.e. it is 84000 yojanas in height from the surface of the earth)
Enclosed by these eight mountain-ranges, the mountain of gold (Meru) shines like (sacrificial) fire surrounded by blades of Kusha grass. (to demarcate its boundaries).
Those (who are in know) say that on the summit of Meru, at the very center, is situated Sata-Kumbhi, (the city of gold), the capital of god Brahma. It covers an area of a ten thousand yojanas and is square in shape.
Surrounding that city (capital of god Brahma), there are eight suburbs (or cities) of the eight guardian deities of the world (such as Indra, Varuna etc.), They are after the model of Sata-Kumbhi, and are build in a style befitting their masters, each city being one fourth in extend of Lord Brahma's capital.
