If you give your life as a prayer, you intensify the prayer beyond all measure. To attain inner peace you must actually give your life, not just your possessions. When you at last give your life bringing into alignment your beliefs and the way you live, then, and only then, can you begin to find inner peace.
Unless we are rooted in God, and rooted in the only sure way of listening to God -- namely, silence -- then we are doomed to spend our lives standing at the window of life and watching the world go by... It strikes me that most of the first part of our lives is spent filling our heads with information. The last part -- and the most important part -- is spent emptying our heads of all the trivia so that our hearts may be free to learn wisdom -- in silence.
