What is "nirjara"

Nirjara is one of the seven fundamental principles, or Tattva in Jain philosophy, and refers to the shedding or removal of accumulated karmas from the atma (soul), essential for breaking free from samsara, the cycle of birth-death and rebirth, by achieving moksha, liberation.

Literally meaning "falling off", the concept is described first in chapter 9 of the classical Jain text, Tattvartha Sutra (True nature of Reality) written by Acharya Umasvati, in 2nd century CE, the only text authoritative in both Svetambara and Digambara sects of Jainism. Later it also finds mention in Dravyasamgraha (Compendium of substances), a 10th-century Jain text by Acharya Nemichandra.
