Greater Bhārata-varṣa
So here it is said… Vyāsadeva, he writes… This Bhagavad-gītā is one of the chapter of Mahābhārata. Mahābhārata means the history of greater India. Formerly Bhārata… “India” is given name by the Westerners, but real name is Bhārata, Bhārata-varṣa. This planet was formerly known as Ilāvṛta-varṣa, and later on, after the Emperor Bharata, this planet was known as Bhārata-varṣa. So Bhārata-varṣa means not only India, but the whole planet. At least five thousand years ago it was known as Bhārata-varṣa. Bhārata-varṣa name is there, but it indicates only India. So this Bhagavad-gītā is a chapter of Mahābhārata. Perhaps you know the book Mahābhārata, “Greater Bhārata-varṣa,” “The History of the Greater Bhārata-varṣa.” That is Mahābhārata.
