āyatastu kumārīto gaṅgāyāḥ pravahāvadhiḥ
tiryagūrdhvaṃ tu vistīrṇaḥ sahasrāṇi daśaiva tu //

There is no field of action for mankind without Bhâratavarṣa. Bhâratavarṣa has nine divisions; Viz.—Indradvîpa, Kaśera, Tāmraparṇî, Gabhastimâna, Nâgadvîpa, Saumya, Gandharva, Vâruṇa; and the ninth is this place, surrounded on all sides by the ocean. The whole of the dvîpa is a thousand yôjanas in extent, from north to south. It is gradually broader from Kumârî (Cape Comorin) to the mouth of the Ganges, whence it has risen to a height of ten thousand yôjanas in an oblique direction.—7-10.
