Love begets love. Like a wave, the love of an individual can evoke compassion in another. The active display of concern warms the many hearts who witness it. The love spreads for many to see. Compassion hen generates community. Others are brought into the swirling dynamic of God's revelation of care. The witness to love can inspire others to carry the tide of concern further.
In every ministry, one is giving something to someone else; in shared silence, one is giving oneself. Sharing interior silence is the giving of one's inmost being to another. When one does this in a group, everyone shares everybody else's level or degree of interior silence. Thus, everyone in the group tends to move to a deeper place than when alone and relying on one's own limited experience.
This is especially the case when silence is penetrated by the gift of interior silence. Then silence is an encounter with the divine presence within. One rests in the conviction of faith and in peace that transcends joy and sorrow. It brings one in face-to-face contact with God, so to speak, a being-to-being exchange.
