The seven islands (dvipas) are known as (1) Jambu, (2) Saka, (3) Salmali, (4) Kusa, (5) Kraunca, (6) Gomeda, or Plaksa, and (7) Puskara. The planets are called dvipa. Outer space is like an ocean of air. Just as there are islands in the watery ocean, these planets in the ocean of space are called dvipas, or islands in outer space. There are nine khandas, known as (1) Bharata, (2) Kinnara, (3) Hari, (4) Kuru, (5) Hiranmaya, (6) Ramyaka, (7) Ilavrta, (8) Bhadrasva and (9) Ketumala. These are different parts of the Jambudvipa. A valley between two mountains is called a khanda or varsa.
