It’s as plain and simple as that. Forgiveness of those who did you wrong, who you perceived did you wrong, who said things you did not like, who made you feel bad, sad, angry, hurt, betrayed. If you do not forgive them, they will continue to hurt you forever.
Not only is it good to forgive others, but to also forgive yourself? How often have you muttered along in your brain how you “should have done this….and should have done that” or to berate yourself for something you said in the heat of the moment? Forgiving yourself is one of the keys to contentment. After all, you always do the best you can at the time and that is all anyone can ask.
