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.
Once when we were walking together, I saw Teilhard fall to his knees just to study a stone. He held it up to the light and ran his fingers carefully over its surfaces, as if he were trying to read the pattern of matter as a language. Watching him that day in the blessed silence of the field, I saw a man who could see light in the very earth under his feet. Because of him I learned not to hate our enemy, and joined with him in the work of serving those who were in need. And sometimes at sunset when the sky was bright with amazing color, I tried to look beyond the trenches — as he did so often — and see the light in this world of ours.
