Jains cite inequalities, sufferings, and pain as evidence for the existence of karma. Various types of karma are classified according to their effects on the potency of the soul. The Jain theory seeks to explain the karmic process by specifying the various causes of karmic influx ("āsrava") and bondage ("bandha"), placing equal emphasis on deeds themselves, and the intentions behind those deeds. The Jain karmic theory attaches great responsibility to individual actions, and eliminates any reliance on some supposed existence of divine grace or retribution. The Jain doctrine also holds that it is possible for us to both modify our karma, and to obtain release from it, through the austerities and purity of conduct.
