There's a thread you follow. It goes among things that change. But it doesn't change. People wonder about what you are pursuing. You have to explain about the thread. But it is hard for others to see. While you hold it you can't get lost. Tragedies happen; people get hurt or die; and you suffer and get old. Nothing you do can stop time's unfolding. You don't ever let go of the thread.
Forgiveness is always necessary when I have the perception that I failed to love and accept myself or another. Forgiveness allows me to let go of any feelings of inadequacy that arise in me. Forgiving myself is the affirmation that I do not buy into the feelings of inadequacy that invariably arise when I judge myself or another. Forgiveness keeps the slate of my heart open for Spirit to write on.
