Anger that is unacknowledged and repressed creates a karmic relationship. Karmic relationships are unpleasant, debilitating and repetitive. When we fail to deal with a traumatic situation we will experience that situation over and over again. Remember the words of Lao Tzu, Because the sage confronts his difficulties he never experiences them. The failure to confront our anger and the practice of forgive and forget both lead to the same inevitable result.
Negative situations continue, personal power is diminished and self-esteem is destroyed.
To forgive and remember is not self-sacrificial like the practice of forgive and forget. Rather it is self-affirming. We forgive those who trespass against us for the advantages that forgiving them brings to us. When we forgive and set effective boundaries we take back our power and increase our self-esteem. No one has the right to abuse us.
