When passions are totally exterminated, all the bound karmic matter gets totally dissociated from the soul and ultimately the soul attains its pure state or liberation. The theory of moral causation necessarily implies rebirth. Every actmust necessarily be followed by its consequence. Liberation means the attainment of pure state of infinite knowledge and infinite bliss. This state is attained on the complete dissociation of the soul from obscuring karmic matter.
Liberation is attained through human body only.
There is no possibility of fall from the state of liberation. For Jainas the liberated perfected soul is God. They do not believe in one world-creator God. This is called samyag-darshana. All knowledge that is associated with and directed by spiritual inclination or faith is spiritually wholesome knowledge.
