In the Indian caste system, a Dalit, often called an untouchable, or an outcaste, is a person who according to traditional Hindu belief does not have any "varnas". Varna refers to the Hindu belief that most humans were supposedly created from different parts of the body of the divinity Purusha. The part from which a varna was supposedly created defines a person's social status with regard to issues such as whom they may marry and which professions they may hold. Dalits fall outside the varnas system and have historically been prevented from doing any but the most menial jobs. (However, a distinction must be made between lower-caste people and Pariahs.) Included are leather-workers (called chamar), carcass handlers (called mahar),poor farmers and landless labourers, night soil scavengers (called bhangi or chura), street handicrafters, folk artists, street cleaners, dhobi, etc. Traditionally, they were treated as pariahs in South Asian society and isolated in their own communities, to the point that even their shadows were avoided by the upper castes. Discrimination against Dalits still exists in rural areas in the private sphere, in ritual matters such as access to eating places and water sources. It has largely disappeared, however, in urban areas and in the public sphere, in rights of movement and access to schools. The earliest rejection of discrimination, at least in spiritual matters, was made as far back as the Bhagavada Gita, which says that no person, no matter what, is barred from enlightenment. Even early Indian texts such as the Rig Veda discourage the abuse of outcastes. The text reads, “Indra, you lifted up the outcast who was oppressed, you have glorified the blind and the lame.” (Rg-Veda 2:13:12) There are an estimated 160 million Dalits in India.
