Prayer is that divine seed whose roots draw food from earthly existence. Like the lotus flower that does not bloom in arable ground but in marshes, prayer thrusts its roots into human misery as if into mud. But the lotus flower does not show any trace of the muddy water from which it drew life; turned toward the sky, it blooms.
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.
