The Caste System in India. The problem of caste is vast, both theoretically and practically. In practice, it is an institution that portends enormous consequences, is a local problem but is capable of wider harm as long as caste exists in India. Hindus are unlikely to intermarry or have social relations with strangers, and if Hindus migrated to other regions of the earth, Indian caste would become a worldwide problem. Theoretically, it has challenged many great scholars who have undertaken a labor of love to dig into its origin. This being the case, I cannot address the issue in its entirety. However, to define the caste system we cannot define caste as an isolated unit in its own right and not as a group within and with defined relationships to the caste system as a whole. Mr. Sinart, an ethnologist who has studied the caste system, draws attention to the idea of ​​pollution as a characteristic of caste. Regarding this point we can safely say that it is not at all a peculiarity of the caste as such. It usually originates in priestly ceremonialism and as a special case of the general belief in purity. Consequently, its necessary connection with caste can be completely denied without harming the functioning of caste. The idea of ​​pollution was linked to the institution of castes only because the caste that enjoyed the highest rank was the priestly one. Well we know that priest and purity are old companions. I can therefore conclude that the idea of ​​pollution is a characteristic of caste only insofar as caste has a religious flavour. The prohibition or rather the absence of mixed marriages (endogamy) is the only one that can be defined as the essence of caste, if correctly understood. This will result in a limit… middle of the paper… rest of the caste formation, it is absolutely necessary to circumscribe a circle outside of which people should not enter into marriages. However, this encirclement to prevent marriages from the outside creates problems from within that are not easy to solve. In the caste system, maintaining equality between the sexes becomes the final goal, because without it endogamy can no longer exist. In other words, in order for endogamy to be preserved, it is necessary to provide marital rights from the inside, otherwise the members of the group will be kicked out of the circle to take care of themselves in every possible way, but to ensure the rights to be provided, it is absolutely necessary to maintain numerical equality between the marriageable units of the two sexes within the group wishing to transform into a cast. Of course a very large disparity is sure to break it.
