In Jambūdvīpa there are nine divisions of land, each extending to a width of 9,000 yojanas, [Note: Ilāvṛta, Bhadrāśva and Ketumālā are exceptions.] completely separated by eight mountain ranges. Āyāmaṇ here means the length. The mountain ranges include the Himālayas. The form is described in the Vāyu Purāṇa: dhanurvat saṁsthite jñeye dve varṣe dakṣiṇottare dīrghāṇi tatra catvāri caturasram ilāvṛtam Two varṣas on the north and south are bow-shaped. Four other varṣas are long and Ilāvṛta is square. The varṣa in the south is Bhārata and that in the north is Uttarakuru. The four long varṣas are Kuṁpuruṣa, Harivarṣa, Ramyaka and Hiranmayāni. Bhadrāśva and Ketumāla are also shaped like bows, bordered by Nīla and Niṣadha mountain ranges running horizontally and entering the sea. Their width is nine thousand yojanas except for Ketumāla and Bhadraśva in the middle. Ilāvṛta is nine thousand yojanas in all four directions from Meru (which has a 16,000 yojana base). Ilāvrta, Bhadrāśva and Ketumālā are thus 34,000 yojanas in width (16,000 + 9000, + 9000).
