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.
For a composer silence is something pregnant with expectation ... the most naturally spiritual medium. The music grows in the spiritual life: the silence of monks, the silence of meditation, the silence of not knowing something, the terrible silence of God when we are confronted with evil in the world. Music has always been intimately connected with the numinous and the immaterial. I increasingly believe that the non-corporeal quality of music can be a direct challenge to the world and its materiality.
