Silence is the highest form of music ... Music of the infinity, referred to as the music of the spheres, is often heard in deep solitude or reflected in natural sounds -- the wind, the ocean, the melody of birds. The single note of a temple gong is far more powerful than an orchestra of one hundred instruments. The clear sound it produces reverberates deep within our mind and body, conveying a sense of infinite peace and bringing us close to the melodious silence of infinity.
"Contemplating is receiving." (St. John of the Cross) What we receive in prayer is the Spirit, who makes all creation new, moment by moment. It is the Spirit who rebirths us within the caves of our hearts. The case is a metaphor for this silent withdrawal, this going away to be alone, to listen, to gestate the Spirit, to rebirth ourselves. The reborn self is the child of wisdom born in solitude.
