In Jain philosophy, Karma plays a crucial role in determining the cycle of birth and rebirth (samsara). According to Jain beliefs, karma is a subtle substance that pervades the universe and binds itself to the soul based on one's actions, thoughts, and intentions. These karmic particles are the reason for the soul's bondage and suffering.
The liberation from this cycle can only be achieved through spiritual purification and complete freedom from karmic bonds. Practices such as penance, right conduct, and self-discipline help in shedding karma and progressing towards moksha, or liberation.
