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.
It is within my power either to serve God, or not to serve. Serving, I add to my own good and the good of the whole world. Not serving, I forfeit my own good and deprive the world of that good, which was in my power to create.
