Translation:

Śrī Śukadeva Gosvāmī said: My dear King, in the opinion of some learned scholars, eight smaller islands surround Jambūdvīpa. When the sons of Mahārāja Sagara were searching all over the world for their lost horse, they dug up the earth, and in this way eight adjoining islands came into existence. The names of these islands are Svarṇaprastha, Candraśukla, Āvartana, Ramaṇaka, Mandara-hariṇa, Pāñcajanya, Siṁhala and Laṅkā.

Purport:

In the Kūrma Purāṇa there is this statement about the desires of the demigods: Although the demigods are situated in exalted positions in the heavenly planets, they nevertheless desire to descend to the land of Bhārata-varṣa on the planet earth. This indicates that even the demigods are unfit to reside in Bhārata-varṣa. Therefore if persons already born in Bhārata-varṣa live like cats and dogs, not taking full advantage of their birth in this land, they are certainly unfortunate.
