The Kambojanvaya Gaudapati of Dinajpore Pillar Inscriptions is stated to be a builder of Siva temple and therefore was devotee of Siva. He is said to be a great bestower of the charities. Kambojavamsatilaka Rajayapala, the first king of the Irda Copper plate is referred to as Parama-saugata (devotee of Buddha). The third ruler Narayanapala Kamboja is stated to be a devotee of god Vishnu. King Nayapala Kamboja, the author of Irda Copper plate is known to have practised Siva cult. There is no information on the Kamboja ruler Dharamapala, but it appears likely that he may have also been a Vedic follower i.e. either Saivite or a Vishnu devotee. The Irda Copper plate has references to Hindu gods, high rising temple buildings as well as to the sacred smokes rising from the Yagya fires into the skies. This again alludes to the Hinduism of the Pala Kambojas. Irda Copper plate also makes special references to the Purohits, Kritivajyas, Dharmagyas and other holy officials. Thus we find that the Kamboja kings of Bengal were mostly Vedic Hindus, of course, with the exception of king Rajyapala. Mention is made of grants of lands and villages to the Purohits in the Burdwan district of east Bengal. According to Prof R. C. Majumdar: More significant, however, is the inclusion of Purohits in the land grants of the Kamboja, Varman and Sena kings of Bengal. It indicates the great importance was attached to religious and social aspects of administration during rules of these dynasties which were all followers of orthodox Hinduism. Dr B. N. Sen says that the Buddhism which had followers in the early Pala and Candra rulers was probably on the decline in Bengal during the 10th century. On the other hand, the Vedic religion was on the rise. Since the Kamboja Pala kings of Bengal were mostly Vedic Hindus, hence they must have got full support from their subject which must have helped them raise a powerful empire in Bengal.
