Col. Dalton, in
his Ethnology of Bengal, has mentioned that the Kharias worshipped the Sun God under the
name of Bero and in praying to Bero they addressed hini as Parameshwar, a Hindu word for
god. The very adoption of the word Parameshwar clearly shows the impact of Hinduism. The
Hinduised Mundas and Oraons abstain from most of the meats, which Hindus consider impure.
The latter aboriginal tribe, the Oraons, is distinguished from the Mundas so far as their
symbols of worship are concerned.
The Mundas normally have no symbols and make no
representation to their gods. The Oraons however, have some visible object of worship,
though it may be a stone or a wooden post or a lump of earth. This symbolization on the
part of the Oraons may have been due to the impact of Hindu influence.
