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.
To the degree that each of us is dedicated to wanting there to be peace in the world, then we have to take responsibility when our own hearts and minds harden and close. We have to be brave enough to soften what is rigid, to find the soft spot and play with it. We have to have that kind of courage and take that kind of responsibility. That's the true practice of peace.
