" Here the earth planet is called ilā. This earth was formerly known as Ilāvṛta-varṣa, and when Mahārāja Parīkṣit ruled the earth it was called Bhārata-varṣa. Actually, Bhārata-varṣa is the name for the entire planet, but gradually Bhārata-varṣa has come to mean India. As India has recently been divided into Pakistan and Hindustan, similarly the earth was formerly called Ilāvṛta-varṣa, but gradually as time passed it was divided by national boundaries. "
