What is the intention of 'sanskritizing' communities?

Sanskritisation of a group has usually the effect of improving its position in the local caste hierarchy. It normally presupposes either an improvement in the economic or political position of the group concerned or a higher group selfconsciousness resulting from its contact with a source of the ‘Great Tradition’ of Hinduism such as a pilgrim the centre or a monastery or a proselytising sect.”
