In Jainism, liberation (moksha) means the soul is free from all karmic bondage and has attained perfect, infinite bliss. A liberated soul (siddha) no longer incarnates and resides in a pure, siddha-world beyond cycle of birth and death.

How one knows or achieves liberation (in practical terms)

• The three jewels: samyak darshan (correct belief), samyak jnana (correct knowledge), and samyak charitra (correct conduct). Together they burn karmas and open the path to liberation.
• Purification of the self: continuous removal of karma through right conduct, austerities, and mental discipline. This includes practicing compassion, truth, non-violence, celibacy (for monks/nuns), and non-possessiveness.
• Key vows and practices (common to many Jain paths):

- Five great vows (ahimsa, satya, asteya, brahmacharya, aparigraha) or the equivalent for householders and ascetics. - Regular repentance (pratikraman) to uproot misdeeds and purify conscience. - Spiritual disciplines like samayik (period of equanimity), deshavar (regulated thoughts), and meditation on the self.

• The karmic result: when all residual karma is burnt off, the soul becomes blissful, omniscient, and free from all bondage. The knowledge may become kevala jnana (infinite/right knowledge) in the liberated state, but the primary experience is complete freedom and bliss, not craving or karma.
• How you “know” you’re liberated in practice: there is no further rebirth; the soul remains in its siddha form in the siddha-loka. This is described as absolute freedom from passion, attachment, and ignorance; the person experiences infinite bliss, infinite knowledge, and infinite perception.

Differences to note (Digambara vs. Śvetāmbara)

• Both traditions agree on liberation as complete freedom from karmic bondage and birth-death cycles, but they describe the path and some doctrinal details a bit differently (e.g., the nature of the final omniscience, and certain ritual practices). The essential aim—purification of the soul and final emancipation—remains the same.

Important practical takeaway

• Focus on the Triple Jewels: align belief, knowledge, and conduct with Jain doctrine.
• Regularly engage in self-purification through vows, right conduct, and sincere penance.
• Cultivate detachment from worldly things and actions that create karmic bondage.
• Seek guidance from knowledgeable Jain teachers and communities to correctly apply the sutras and ethics in daily life.
