"The raising of one's mind and heart to God in thanksgiving and in praise of His glory. It can also include the requesting of good things from God. It is an act by which one enters into a loving communion with God. "Prayer is the response of faith to the free promise of salvation and also a response of love to the thirst of the only Son of God". (CCC no. 2561)" -- From the United States Catholic Catechism for Adults.
