Prayaschitta

prayaschitta atonement for sin; the numerous penances prescribed in the scriptures — such as fasting, begging, and performing unusual austerities — to absolve oneself of sins. Such acts can remove the inauspicious karma that is produced by committing sin, but they cannot remove the desire or susceptibility to commit sin in the future, and they cannot absolve the soul of offences against the Lord’s Name or His devotees.
