SILENCE: an energy which extends beyond the furthest reaches of the universe — and never vanishes, a quiet which pervades every particle of this world, and glides through the blackness of the great harbor by night, and speaks differently by day. Speech is the body of silence: the word floats up from silence; it flows back into silence. The word of relationship and the quiet of the heart are inseparable — like love and the silence from which it is born, and the rest to which it returns, unceasingly.
The smile of the contemplative in the presence of the Beloved is merely a physical expression of the total joy one perceives as one communes with God. St. Bernard used to say, "The joy of being in love is in the very loving." In other words, joy is not to be sought for itself, but is a by-product of love, and the smile is but the physical, exterior expression of the inner joy-love.
