Silence is the property, the contemplative quality, the fruit of faith. Interior, mystical silence is a silence which stems from the intensity of loving faith ... the interior result of a heart that loves intensely. The presence in our hearts of a secret to be kept brings about a density which is interior silence. Communication of secrets is the sign which manifests and proves the friendship and total trust of a friend.
It is all too easy and too simple to disdain as "superstition" everything one cannot understand, but the ancients themselves knew very well what they meant when they used symbolic language...the Spirit can always come back to breathe fresh life into the symbols and rites and give them back their lost meaning and the fullness of their original virtue.
