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.
Nicholas of Cusa described human creativity as a participation in the act of God creating the cosmos. God creates the cosmos, we create the microcosmos, the "human world". As we do our daily work, make our homes and marriages, raise our children, and fabricate a culture, we are all being creative... The ultimate work is an engagement with soul, responding to the demands of fate and tending the details of life as it presents itself. We may get to a point where our external labors and the OPUS of the soul are one and the same, inseparable. Then the satisfactions of our work will be deep and long lasting, undone neither by failures nor by flashes of success.
