In 320 a native Indian dynasty, the Guptas, came to the throne and inaugurated a revival of Hinduism, to which religion we must now turn. To speak of the revival of Hinduism does not mean that in the previous period it had been dead or torpid. Indeed we know that there was a Hindu reaction against the Buddhism of Asoka about 150 B.C. But, on the whole, from the time of Asoka onwards Buddhism had been the principal religion of India, and before the Gupta era there are hardly any records of donations made to Brahmans. Yet during these centuries they were not despised or oppressed. They produced much literature[18]: their schools of philosophy and ritual did not decay and they gradually made good their claim to be the priests of India's gods, whoever those gods might be. The difference between the old religion and the new lies in this. The Brâhmanas and Upanishads describe practices and doctrines of considerable variety but still all the property of a privileged class in a special region. They do not represent popular religion nor the religion of India as a whole. But in the Gupta period Hinduism began to do this. It is not a system like Islam or even Buddhism but a parliament of religions, of which every Indian creed can become a member on condition of observing some simple rules of the house, such as respect for Brahmans and theoretical acceptance of the Veda. Nothing is abolished: the ancient rites and texts preserve their mysterious power and kings perform the horse-sacrifice. But side by side with this, deities unknown to the Veda rise to the first rank and it is frankly admitted that new revelations more suited to the age have been given to mankind. Art too enters on a new phase. In the early Indian sculptures deities are mostly portrayed in human form, but in about the first century of our era there is seen a tendency to depict them with many heads and limbs and this tendency grows stronger until in mediaeval times it is predominant. It has its origin in symbolism. The deity is thought of as carrying many insignia, as performing more actions than two hands can indicate; the worshipper is taught to think of him as appearing in this shape and the artist does not hesitate to represent it in paint and stone. As we have seen, the change which came over Buddhism was partly due to foreign influences and no doubt they affected most Indian creeds. But the prodigious amplification of Hinduism was mainly due to the absorption of beliefs prevalent in Indian districts other than the homes of the ancient Brahmans. Thus south Indian religion is characterized when we first know it by its emotional tone and it resulted in the mediaeval Sivaism of the Tamil country. In another region, probably in the west, grew up the monotheism of the Bhâgavatas, which was the parent of Vishnuism.
