The Nature of Forgiveness
Most psychologists recommend mustering up genuine compassion for those who have wronged us, and moving on from the past, instead of allowing bitterness and anger toward others eat away at us. Although burying the hatchet usually brings peace to the soul, there may be some exceptions to that advise, such as a case of sexual abuse. Sometimes a victim becomes more empowered when given permission to not forgive.
Equally, and perhaps more important, is learning to acknowledge your missteps and forgive yourself. Self-forgiveness is often the first step toward a more loving and positive relationship with yourself, and therefore with others.
