Silence is the language spoken by solitude. There is something awesome and breathtaking about real silence; it is numinous, pulling us out of self-containment and calling us toward the invisible. Spiritual seekers "home in" on silence as homing pigeons to their roost, because therein lies the language for personal communication with the sacred. Silence accompanies us into our innermost selves where we are present to the sacred. When word breaks into that kind of silence, there is communion.
Like justness in a judge's decision, or beauty in a painting, soul is a quality of absoluteness in something relative. Understood profoundly, people are connected to the holiness of the world in such a way that they reveal a dimension of holiness in themselves, a dimension of depth that is absolute.
