Is it possible to classify all the jatis that exist in India hierarchically using some or another set of criteria?
This question does not allow an unambiguous answer: perhaps it is possible, perhaps it is not. The British tried to develop such a classificatory system, which they called ‘the caste system’, and gave up on this attempt after about 30 years.
OK, let us choose any one meaning of the term ‘relations’. Tell me now, is it possible to describe/classify all the Jatis in India as though all Jatis are related to each other in a, say, hierarchical relationship?
My hypothesis is: No, it is not possible to describe all the jatis in such a manner.
