It is well known that between the Vedic period, and that described in the epic poems, great modifications occurred in the religion and social customs of the Indian people. Since the Epic period, further changes have taken place; so that the orthodox Hinduism, of the present day, differs much from that represented in the Mahābhārata. Religious vicissitudes have also occurred outside the Brahmanic pale. The Buddhist religion has become extinguished in India. Vast numbers of the people, too, have been converted—many of them forcibly—to the faith of Islām. Notwithstanding all this, however, many of the old deities still live. The Nāga rajas are worshipped as demigods; the sun, the cedar, and the serpent are held sacred; and Indra and his Devas have still their worshippers and their temples, as they had in the days described in the Mahābharāta.
