Kusa

Kusa is an island or Dwipa. In the Puranas it is mentioned that Kusa is the name of the fourth of the great insular continents. The width of this island is 6,400,000 miles or, in other words, twice the width of Salmali Dwipa. It is named from a dump of Kusa grass (Poa) growing there. The island is surrounded by an ocean of clarified butter or Ghrita Sea.

Hindu Values
The Hindu mythology says that the entire Universe is divided into seven concentric island continents. These seven islands are split by the seven encircling oceans, each double the size of the preceding one. The seven continents of the Puranas are; Jambudwipa enclosed by salt-water, Plaksadwipa by sugarcane juice, Salmalidwipa by wine, Kusadwipa by ghee, Krounchadwipa by curd, Sakhadwipa by milk and Pushkaradwipa by water.

The inhabitants of this island worship the supreme personality of Godhead in the form of Agni, the fire-god. There reside mankind along with Daityas and Danavas, as well as with spirits of heaven and Gods.
