State any one set of principles on which caste system is based.
The caste system can be understood as the combination of two sets of principles, one based on difference and separation and the other on wholism and hierarchy.
Each caste is supposed to be different from – and is therefore strictly separated from – every other caste. Many of the scriptural rules of caste are thus designed to prevent the mixing of castes – rules ranging from marriage, food sharing and social interaction to occupation.
These different and separated castes do not have an individual existence – they can only exist in relation to a larger whole, the totality of society consisting of all castes. Further, this societal whole or system is a hierarchical rather than egalitarian system. Each individual caste occupies not just a distinct place, but also an ordered rank – a particular position in a ladder-like arrangement going from highest to lowest.
