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.
If I set my heart upon another person, then I cannot live without that person. My heart becomes divided. If I give my heart to my life, on the other hand, if I give my heart to the journey with God, then my heart can be whole in a relationship with another. I can be heart and soul in the relationship because I am heart and soul in the journey of my life.
