Chandala
Chandala (Sanskrit: चांडाल, "caṇḍāla") is a Sanskrit word for someone who deals with disposal of corpses, and is a Hindu lower caste, traditionally considered to be untouchable. A female member of this caste is known as a "Caṇḍālī". History. Varṇa was a hierarchical social order in ancient India, based on the Vedas. Since the Vedic corpus constitute the earliest literary source, it came to be seen as the origin of caste society. In this view of caste, "varṇa"s were created on a particular occasion and have remained virtually unchanged. In this ordering of society, notions of purity and pollution  were central, and activities were delineated in this context. "Varṇa" divides the society into four groups ordered in a hierarchy; beyond these, outside the system, lies a fifth group known as the "untouchables", of which the Chandala became a constituent part. The first mention of the fourfold varṇa division is found in the later "Rigveda". Vedic literature also mentions some groups such as Ayogava, Chandala, Nishada, and Paulkasa which were outside the four-"varṇa" classification. They were referred to as belonging to the 'panchama varṇa' or "panchamas", meaning fifth. The "Yajur-veda" mentions their degradation from the "varṇa" classes, mentioning the  Chandala group in particular, who were said to be the untouchable class of people born of the union between a Shudra male and a Brahmin female. There are frequent references to the forest-dwellers in the post-Rigvedic literature; the Chandalas were one of these primitive people, who belonged to the fringes of the society. In India, except Bengal, "Chandal" is also used as a pejorative reference to a mean or low person.
