Existential prayer is one form of mystical contemplation. It is the prayer of just being. It has few words; and perhaps it has no images at all. In this prayer I just AM -- like the flower of the field or the birds of the air; and by just being I give glory to God.
The all-important aim in meditation is to allow God's mysterious and silent presence within us to become more and more not only a reality, but the reality which gives meaning, shape and purpose to everything we do, to everything we are.
