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 outward work can never be small if the inward one is great, and the outward work can never be great if the inward is small or of little worth.
