Jain philosophy posits that karma is central to the cycle of reincarnation (samsara). Jain doctrine describes karma as a subtle universal substance that adheres to the soul due to actions, thoughts, and intentions, causing the soul's bondage and suffering. Liberation from this cycle requires spiritual purification and the complete severance of karmic ties. Through practices like penance, right conduct, and self-discipline, individuals can shed karma and advance towards moksha, or spiritual freedom.
