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.
The parallelism of the psalms is a key to praying them. Just as the rhythm of music invites us to join in a dance, the rhythm of the psalms invites us to join in a dance, the rhythm of the psalms invites us to step into them with our whole self ... Repetition in prayer is a way of holding God in remembrance. The images of such prayer lodge deep within us and surface at other periods of our life. When we move quickly from one idea to another, it is difficult to let any one thought sink in and deepen within us. By quietly reiterating a theme or image, a psalm calms our restless hearts and gently leads us into a prayerful attitude.
