2.2.18

purveṇa mandaro nāma dakṣiṇe gandhamādanaḥ /
viplalaḥ paścime pārśve mupārśvaścottara smṛtaḥ //

next Kimpurusha, between Himaván and Hemakút́a; north of the latter, and south of Nishadha, is Hariversha; north of Meru is Ramyaka, extending from the Níla or blue mountains to the Śweta (or white) mountains; Hirańmaya lies between the Śweta and Śringí ranges; and Uttarakuru is beyond the latter, following the same direction as Bhárata. Each of these is nine thousand Yojanas in extent. Ilávrita is of similar dimensions, but in the centre of it is the golden mountain Meru, and the country extends nine thousand Yojanas in each direction from the four sides of the mountain. There are four mountains in this Varsha, formed as buttresses to Meru, each ten thousand Yojanas in elevation: that on the east is called Mandara; that on the south, Gandhamádana; that on the west, Vipula; and that on the north, Supárśwa: on each of these stands severally a Kadamba-tree, a Jambu-tree, a Pípal, and a Vat́a; each spreading over eleven hundred Yojanas, and towering aloft like banners on the mountains. From the Jambu-tree the insular continent Jambu-dwípa derives its appellations. The apples of that tree are as large as elephants: when they are rotten, they fall upon the crest of the mountain, and from their expressed juice is formed the Jambu river, the waters of which are drunk by the inhabitants; and in consequence of drinking of that stream, they pass their days in content and health, being subject neither to perspiration, to foul odours, to decrepitude, nor organic decay. The soil on the banks of the river, absorbing the Jambu juice, and being dried by gentle breezes, becomes the gold termed Jámbunada, of which the ornaments of the Siddhas are fabricated.
