Prayer is not a way to get what we want to happen, like the remote control that comes with the television set. I think prayer may be less about asking for the things we are attached to than it is about relinquishing our attachments in some way. It can take us beyond fear, which is an attachment, and beyond hope, which is another form of attachment. It can help us remember the nature of the world and the nature of life, not on an intellectual level but in a deep and experiential way. When we pray, we don't change the world, we change ourselves.
Gratitude is the vision of the Giver, not of the gift. It comes from God. Hope and fear are like the two wings of a bird when it is flying straight to its destination. If one wing fails, its flight fails and if both fail, it dies. Hope is the vision of God in perfect beauty.
