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.
At times God seems to give us stones impossible to digest. In these moments think of the pearl oyster: it retains the accidental grain of sand within itself for a long time, constantly bathing in it with its secretions. In due time a magnificent pearl is created. In like manner the animosities and antipathies that make their way into our hearts are seemingly indigestible pebbles. However, if we keep them wrapped in prayer, they will become pearls of love. Prayer provokes this miracle of love. Indeed, what appears to be indigestible can become real nourishment for prayer.
