The hero Vapushmat was king of the next or Śálmala-dwípa, whose seven sons also gave designations to seven Varshas, or divisions. Their names were Śweta, Háríta, Jímúta, Rohita, Vaidyuta, Mánasa, and Suprabha. The Ikshu sea is encompassed by the continent of Sálmala, which is twice its extent. There are seven principal mountain ranges, abounding in precious gems, and dividing the Varshas from each other; and there are also seven chief rivers. The mountains are called Kumuda, Unnata, Valáhaka, Drona, fertile in medicinal herbs, Kanka, Mahisha, and Kakkudwat. The rivers are Yauní, Toyá, Vitrishńá, Chandrá, Śuklá, Vimochaní, and Nivritti; all whose waters cleanse away sins. The Brahmans, Kshetriyas, Vaiśyas, and Śúdras of this Dwípa, called severally Kapilas, Arunas, Pítas, and Rohitas (or tawny, purple, yellow, and red), worship the imperishable soul of all things, Vishńu, in the form of Váyu (wind), with pious rites, and enjoy frequent association with the gods. A large Śálmalí (silk-cotton) tree grows in this Dwípa, and gives it its name. The Dwípa is surrounded by the Surá sea (sea of wine), of the same extent as itself.
