Sanskritisation (or Sanskritization) is a term in sociology which refers to the process by which castes or tribes placed lower in the caste hierarchy seek 'upward' mobility by emulating the rituals and practices of the dominant castes or upper castes. It is a process similar to "passing" in sociological terms. This term was made popular by Indian sociologist M. N. Srinivas in the 1950s.
In a broader sense, also called Brahmanisation, it is a historical process in which "local" Indian religious traditions become syncretised, or aligned to and absorbed within the Brahmanical religion, resulting in the pan-Indian religion of Hinduism.
Srinivas defined Sanskritisation as a process by which
a low or middle Hindu caste, or tribal or other group, changes its customs, ritual, ideology, and way of life in the direction of a high and frequently twice-born caste. Generally such changes are followed by a claim to a higher position in the caste hierarchy than that traditionally conceded to the claimant class by the local community ... ."
In a broader sense, Sanskritisation is
the process whereby "local" or regional forms of culture and religion – local deities, rituals, literary genres – become identified with the 'great tradition' of Sanskrit literature and culture: namely the culture and religion of orthodox, Aryan, Brahmans, which accepts the Veda as revelation and, generally, adheres to varnasrama-dharma.
In this process, local traditions ("little traditions") become integrated into the "great tradition" of Brahmanical religion, disseminating Sanskrit texts and Brahmanical ideas throughout India, and abroad. This facilitated the development of the Hindu synthesis, in which the Brahmanical tradition absorbed "local popular traditions of ritual and ideology."
According to Srinivas, Sanskritisation is not just the adoption of new customs and habits, but also includes exposure to "new" ideas and values appearing in Sanskrit literature. He says the words Karma, dharma, papa, maya, samsara, and moksha are the most common Sanskrit theological ideas which become common in the talk of people who are sanskritised.
