The Buddhist cosmology divides the (circle of the earth) into three separate levels: Kāmadhātu (Desire realm), Rūpadhātu (Form realm), and Ārūpyadhātu (Formless realm). In the Kāmadhātu is located Mount Sumeru which is said to be surrounded by four island-continents. "The southernmost island is called Jambudvīpa". The other three continents of Buddhist accounts around Sumeru are not accessible to humans from Jambudvīpa. Jambudvīpa is shaped like a triangle with a blunted point facing south, somewhat like the Indian subcontinent. In its center is a gigantic Jambu tree from which the continent takes its name, meaning "Jambu Island".
