“The three upper classes in the Hindu caste system include the Brahmins (priests, intellectuals), the Kshatriyas (warriors, leaders) and the Vaishyas (merchants, traders). The two levels of the lower castes include the Sudras (manual laborers) and the Untouchables (street cleaners, latrine cleaners).”
