A new proverb dealing with teshuvah has been posted the Mishlei section as of Sunday, January 3.
There are times when a person is overcome by a mood of selfishness or ego that causes him to violate his inner conscience and act to please himself. Such violation is called sin and is the greatest challenge that a man must face.
Although man is vulnerable to sin, the Creator provided him with a means to recover from the consequences of sinful behavior. Essentially this process of teshuvah (returning) involves sincere regret for the sins of the past and earnest resolve to avoid sinful behavior in the future. Teshuvah is a demanding process, but Hashem has promised that it will be rewarded by forgiveness and a clean slate so that man can continue with his life.
