Jain (Skt. Jaina) or Nigrantha ('the naked ones') (Skt.; Tib. གཅེར་བུ་པ་, cherbupa, Wyl. gcer bu pa) — a non-Buddhist school of ancient India. The Jains, or Nigranthas, are followers of Rishabba Jina (Skt. Ṛshabha Jina). They assert that all objects of knowledge are included in nine categories:
- Contamination (Tib. ཟག་པ་, zag pa)
- Wearing down
- Action (karma)
Liberation, they say, is attained through asceticism, such as going naked, not speaking, the five fires (in the four directions and the sun above), and so on, until past karma is exhausted. With no new karma created, one is reborn at the top of the world, in a white realm, shaped like an upside down umbrella.
