Our being is silent, but our existence is noisy. Yet when our noisy actions stop, there is a ground of silence always there. Contemplatives must be in contact with that ground and communicate from that level to keep silence alive for other people.
The experience of prayer is the experience of coming into full union with the energy that created the universe. What Christianity has to proclaim to the world is that that energy is LOVE and it is the well-spring out of which all creation flows. It is the well-spring that gives each one of us the creative power to be the person we are called to be -- a person rooted and formed in love.
