Doing penance is an act of repentance, usually in the form of a religious ritual. It is often done to make up for wrongdoings or sins. The term 'ATONE' is derived from the Old English word 'atōnian', which means to reconcile or make amends. The act of atonement is often seen as a way to restore balance and harmony between oneself and God. By doing penance, one can show remorse and seek forgiveness for their transgressions.
