Prayer is action you take in order to realize yourself fully with your neighbor and with God. It is the fulfillment of the great commandment to love God and neighbor. It opens the gate to heaven; heaven is the complete recognition of your potential to be who you really are, uniting you in pain and joy with God and with the whole world. Embracing your own alienation and brokenness with honesty and openness is the foundation of prayer; prayer can be choked off by self-will. Prayer is anything you think, say, do, or feel that opens you up and out to love.
Perhaps there was in Beethoven the man, a child inside that never grew up and to the end of his life remained a creature of grace and innocence and trust even in his moments of greatest despair. And that innocent spirit speaks to us of hope and future and immortality.
