People say eyes are the window to the soul, I think its the hands.  Grasping, reaching, touching, holding, caressing, manufacturing.  After a long day, sitting in the quiet, your hands hold the weight of your tired head, giving you a precious few seconds to be idle with your soul.  To turn your reflection inward for a moment, casting the gaze inside.  Your hands are still there supporting you, guiding you through the darkness.
