The rule of Endogamy states that any sexual and marital unions between people of different castes would lead to ritual impurity and the children reproduced from them would forever be impure including a woman.
Endogamy is the custom of marriage taking place within the same social groups like castes, and gotras. It is prevalent in a caste-based society like India where inter-caste marriage is still not in frequent. The social and cultural gap among all castes towards each others resulting in marrying in different castes would lead to dismantling the society and life of couples and their future offspring. Endogamy is practiced in order to keep their community homogenous and free from evils that could be entered by marrying lower castes. It results in an increment in the frequency of cousin marriage in the population.
