No one really knows what the soul is, but tremble forth it does and, just as mysteriously, shudders away again...The soul is the name for the unifying principle, power, or energy that is at the center of our being. To be in touch with soul means going back to the sacred source, the site of life-releasing energy, the activating force of life; to venture forth and confront the world in all its marvelous and terrifying forces, to make sacred our hours here; to learn to pay such supreme attention to the world that eternity blazes into time with our holy longing. Soul-making, this.
I believe that works that touch the Divine or teach us or are still with us centuries after their creation are the ones that did not come out of a place of power or control or techniques, but came at the moment when the heart let go and God answered the question.
