Our meditation should begin with the realization of our NOTHINGNESS AND HELPLESSNESS in the presence of God... "Finding our heart" and recovering this awareness of our inmost identity implies the recognition that our external, everyday self is to a great extent a mask and a fabrication. It is not our true self. And, indeed, our true self is not easy to find. IT IS HIDDEN IN OBSCURITY AND "NOTHINGNESS" at the center where we are in direct dependence on God.
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.
