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.
Every breath is a sacrament, an affirmation of our connection with all other living things, a renewal of our link with our ancestors and a contribution to generations yet to come. Our breath is a part of life's breath, the ocean of air that envelopes the earth.
~ David Suzuki in THE SACRED BALANCE: REDISCOVERING OUR PLACE IN NATURE
