To be born a Hindu in India is to enter the caste system, one of the world's longest surviving forms of social stratification. Embedded in Indian culture for the past 1,500 years, the caste system follows a basic precept: All men are created unequal. The ranks in Hindu society come from a legend in which the main groupings, or varnas, emerge from a primordial being. From the mouth come the Brahmans%u2014the priests and teachers. From the arms come the Kshatriyas%u2014the rulers and soldiers. From the thighs come the Vaisyas%u2014merchants and traders. From the feet come the Sudras%u2014laborers. Each varna in turn contains hundreds of hereditary castes and subcastes with their own pecking orders.
A fifth group describes the people who are achuta, or untouchable. The primordial being does not claim them. Untouchables are outcasts%u2014people considered too impure, too polluted, to rank as worthy beings. Prejudice defines their lives, particularly in the rural areas, where nearly three-quarters of India's people live. Untouchables are shunned, insulted, banned from temples and higher caste homes, made to eat and drink from separate utensils in public places, and, in extreme but not uncommon cases, are raped, burned, lynched, and gunned down
