Silence brings us far beyond soundlessness, it quiets our senses and spirit and tunes our heart for a deep and delicate listening. For, silence is a primal language which speaks and listens from the heart. It is not the only language through which we communicate with God, but it is a necessary second language since the knowledge of God is received in divine silence. Like all other languages, silence is easily forgotten without practice and discipline.

Meditation consists in learning to focus and to control the mind. When the mind is stilled, then the light of the intellect begins to shine. The mind is ordinarily scattered and dissipated, but gather the mind into one and then the pure light shines in the mirror which is oneself. Speech is the movement by which we go out of ourselves to communicate with another. Meditation takes us within ourselves. It is a process of inward withdrawal, a centering in the place of inner detachment, a staying of the mind upon God.
