Forgiveness is the finishing of old business - Joan Borysenko

Forgiveness ... is the finishing of old business that allows us to experience the present, free of contamination from the past.
- Joan Borysenko

Forgiveness is not always easy. At times, it feels more painful than the wound we suffered, to forgive the one that inflicted it. And yet, there is no peace without forgiveness.
- Marianne Williamson

People are often unreasonable, illogical, and self-centered;
... Forgive them anyway.
- Kent Keith (often attributed to Mother Teresa)

Forgiving is not a gift to someone else - Forgiving is your gift to yourself - a great gift - the gift of happiness.
- jlh

Forgive those who have injured you - not because they deserve your forgiveness, but because you can never be happy until you release your anger and grant forgiveness.
