There are no limits on true self-giving. It is not just to those one likes that one makes the offering. This involves a love that issues from the very CENTER of the person's being, directed to the CENTER of the other person's being, a love that gives ALL that the person is in order to foster the other person's life, a love that is offered to EVERYONE, without exception and without condition. The love is not offered to people because they are one's friends; people become "friends" because one loves them.
Forgiveness means "to give up resentment against". When we give up our resentment against another person, we are consciously choosing to not allow that person to exercise the power to make us angry. Forgiveness acknowledges that we are ultimately responsible for the world we create and how we feel about it... Through forgiveness we encounter the frail essence of the other ... this creates fertile ground where miracles occur, where avowed enemies join hands as friends.
