The essence of silence is self-emptiness, docility, receptivity, detachment, desire, listening, communion. Every act of silence is a little Advent. A Luigi Giussaní sums it up, "Silence is not merely keeping quiet, but it is the attitude of one who lives standing before a 'You' who is presenting, entreating a 'you' who is present." Teresa of Avila refers to contemplative prayer as the "prayer of quiet." Such prayerful silence enhances our ability and eagerness to listen to our Beloved. In this silence, the one in love remains perfectly content just to behold the Beloved, gazing in a state of holy and tranquil abiding. Silence speaks to silence.
Silence provides an atmosphere for prayer, and it preserves the growth that has been gained in prayer. People who begin to speak immediately after prayer in common, will not be able to preserve the fruits of their prayer. Their Recollection is dissipated, and they pour out all that has been accumulated within them. The observance of silence, on the other hand, allows the spirit of prayer to reverberate and take root in the heart.
