It offers an excellent solution to rid one's soul of karmas. By practicing these virtues, one can ultimately purge himself of the past karmas and stop the influx of the new ones and ultimately purify one's soul. Since the subject falls in the area of spiritualism, the validity is rather difficult. If we believe in the life after death and believe that every one has to pay a price for his evil deeds either now or later, then karma theory holds good nicely. If the Cause and effect holds good in our daily material lives, then the theory of karma must hold good in our spiritual lives.
Motives count a lot in Jainism.
Hence the very heavy emphasis on pure thoughts in this religion. They can be stopped by good conduct and proper mental activity. The karmic accounts can be settled by practicing the virtues of truth, non-violence, austerity, discipline and self sacrifice.
