Those who are learned love to talk about what they know; and as they know much, they talk much. Yet to hear God, they must LISTEN. The learned often make a storage room of their mind, where so much is stored that there is no room left for God to enter and dwell in it ... The learned like to argue for the sake of arguing. It becomes a game, and in the end they love the argument and miss the opportunity to hear 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.
