2.4.p3

The heroic Vapusmat is the sovereign of the Salmala-dwipa; do thou hear the names of his seven sons who gave names to the seven divisions of this insular continent. They were Sweta, Harita, Jimuta, Rohita, Vaidyuta, Manasa, and Suprabha. The sea of molasses is girt by this insular continent on all sides, which is twice in extent. There are seven mountain ranges containing precious jems and dividing the Dwipa and there are seven rivers. They are Kumuda, Unnata, Valahaka, Drona, abounding in medicinal herbs, Kanka, Mahisha and Kakkudwat. The principal rivers are Yauni, Toya, Vitrishna, Chandra, Sukla, Vimochani and Nivritti; the waters of all these remove sins. All the varsas namely Sweta, Harita, Vaidyuta, Manasa, Jimuta and Suprava are very charming. All these varsas are peopled by men of four castes. The four castes, O great Muni, who reside in Salmala-dwipa, are severally known as Kapilas, Arunas, Pitas and Rohitas (or tawny, purple, yellow and red) corresponding to Brahmanas, Kshatriyas, Vaiçyas and Sudras, who all perform sacrifices and worship the Great undecaying Vishnu, the soul of all things, in the form of Vayu (wind) with pious rites. The people there enjoy frequent association with the celestials. There is a huge Salmali (silk-cotton) tree in this insular continent, which gives its name and affords delight to gods.
