Puranic cosmography divides our earth into seven concentric islands called Jambu, Plaksha, Salmali, Kushadvipa, Kraunca, Sakaldwipiya, and Pushkara, that are separated by the seven encircling seas. The insular continent Jambudvipa forms the innermost concentric island in the scheme of continents. Jambudvipa includes nine countries (varṣa) and nine mountains. The land of Illa-vrta lies at the center of Jambudivipa at whose center is located Mount Meru(Hindu Kush). The land of Uttarakuru lies to the north of Mount Meru/ Kailash.
