A son who takes birth under circumstances other than those mentioned above, is considered as a very inferior one. If a person of a lower caste begets a son upon a woman of a superior caste, such son is regarded as outside the pale of the four pure castes. Indeed, such son becomes an object of derision with the four principal castes.
