The division of the Hindus into classes or castes, with fixed occupations, existed from the earliest times. It is supposed by some to have been founded upon conquest, the first three castes being composed of a foreign race, who subdued the natives of the country and reduced them to an inferior caste. Others trace it to the fondness of perpetuating, by descent from father to son, certain offices or occupations.
The Hindu tradition gives the following account of the origin of the various castes: At the creation Brahma resolved to give the earth inhabitants who should be direct emanations from his own body. Accordingly from his mouth came forth the eldest born, Brahma (the priest), to whom he confided the four Vedas; from his right arm issued Shatriya (the warrior), and from his left, the warrior's wife. His thighs produced Vaissyas, male and female (agriculturists and traders), and lastly from his feet sprang Sudras (mechanics and laborers).
The four sons of Brahma, so significantly brought into the world, became the fathers of the human race, and heads of their respective castes. They were commanded to regard the four Vedas as containing all the rules of their faith, and all that was necessary to guide them in their religious ceremonies. They were also commanded to take rank in the order of their birth, the Brahmans uppermost, as having sprung from the head of Brahma.
A strong line of demarcation is drawn between the first three castes and the Sudras. The former are allowed to receive instruction from the Vedas, which is not permitted to the Sudras. The Brahmans possess the privilege of teaching the Vedas, and were in former times in exclusive possession of all knowledge. Though the sovereign of the country was chosen from the Shatriya class, also called Rajputs, the Brahmans possessed the real power, and were the royal counsellors, the judges and magistrates of the country; their persons and property were inviolable; and though they committed the greatest crimes, they could only be banished from the kingdom. They were to be treated by sovereigns with the greatest respect, for "a Brahman, whether learned or ignorant, is a powerful divinity."
When the Brahman arrives at years of maturity it becomes his duty to marry. He ought to be supported by the contributions of the rich, and not to be obliged to gain his subsistence by any laborious or productive occupation. But as all the Brahmans could not be maintained by the working classes of the community, it was found necessary to allow them to engage in productive employments.
We need say little of the two intermediate classes, whose rank and privileges may be readily inferred from their occupations. The Sudras or fourth class are bound to servile attendance on the higher classes, especially the Brahmans, but they may follow mechanical occupations and practical arts, as painting and writing, or become traders or husbandmen. Consequently they sometimes grow rich, and it will also sometimes happen that Brahmans become poor. That fact works its usual consequence, and rich Sudras sometimes employ poor Brahmans in menial occupations.
There is another class lower even than the Sudras, for it is not one of the original pure classes, but springs from an unauthorized union of individuals of different castes. These are the Pariahs, who are employed in the lowest services and treated with the utmost severity. They are compelled to do what no one else can do without pollution. They are not only considered unclean themselves, but they render unclean everything they touch. They are deprived of all civil rights, and stigmatized by particular laws regulating their mode of life, their houses, and their furniture. They are not allowed to visit the pagodas or temples of the other castes, but have their own pagodas and religious exercises. They are not suffered to enter the houses of the other castes; if it is done incautiously or from necessity, the place must be purified by religious ceremonies. They must not appear at public markets, and are confined to the use of particular wells, which they are obliged to surround with bones of animals, to warn others against using them. They dwell in miserable hovels, distant from cities and villages, and are under no restrictions in regard to food, which last is not a privilege, but a mark of ignominy, as if they were so degraded that nothing could pollute them. The three higher castes are prohibited entirely the use of flesh. The fourth is allowed to use all kinds except beef, but only the lowest caste is allowed every kind of food without restriction.
