"The Mahabharata carries a complete picture of this cultural unity in its tîrtha-yãtrã-parva, which is part of the larger Vana-parva. The Pandavas accompany their Purohita, Dhaumya, on a long pilgrimage to all parts of Bharatavarsha. They pay their homage to many mountains, rivers, saMgamas, lakes, tanks, forest groves and other sacred shrines which had become hallowed by association with Gods and Goddesses, rishis and munis, satees and sãdhvees, heroes and heroines. And they feel fulfilled as they never did before or after in their long lives. The same Pandavas made an imperial conquest of the whole country, not once but twice and performed a rãjasûya yajña at the end of each triumph. But the Pandava empire is a faint memory of the forgotten past. On the other hand, the sacred spots which the Pandavas visited during their one and only pilgrimage, draw millions of devotees in our own days as they did in the distant past, long before the Pandavas appeared on the scene. .... The Ramayana, the Puranas and the Dharmashastras paint the same portrait of an ancient land, every spot of which is sacred to some cultural memory or the other. The Jainagama and the Tripitaka speak again and again of sixteen Mahajanapadas, which spanned the spread of Bharatavarsha in the life-time of Bhagvan Mahavira and the Buddha. Even a dry compendium on grammar, the Ashtadhyayi of Panini, provides a near complete count of all the Janapadas in ancient India-Gandhara and Kamboja, Sindhu and Sauvira, Kashmir and Kekaya, Madra and Trigarta, Kuru and Panchala, Kaushala and Kashi, Magadha and Videha, Anga and Vanga, Kirata and Kamarupa, Suhma and Udra, Vatsa and Matsya, Abhira and Avanti, Nishadha and Vidarbha, Dandakaranya and Andhra, Karnataka and Kerala, Chola and Pandya. The epic poetry poured out by Kalidasa, Magha, Bharavi and Sriharsha continues the same tradition of talking endlessly about Bharatavarsha as a single and indivisible geographical entity, as a karmabhûmi for Gods and Goddesses, Brahmarshis and Rajarshis, and as higher than heaven for all those who have had the good fortune of being born in it."
