Deep within us, amid our differentiations as individuals and nations and species, is the desire for oneness. This holy longing is found not only in the human soul but in the soul of the universe, at the heart of everything that has being. We are not an exception to the universe. We are an expression of the universe. Our longings are a unique manifestation of the universe's longings. In listening to the depths of life, within our lives and within every life, we will hear the longings of the One that are deeper than the fears that divide us...There is no such thing as ultimate separation between one part of the universe and an-other, between the well-being of the human species and earth's other species, between the life of one nation and the rest of the world. We and all people, we and those who have gone before us, we and all creatures, we and the universe are traveling together in one river of life. We carry each other within us. And the universe carries us within itself.
Leonardo da Vinci knew that God helps those who help themselves and that this could be hard work. The labor that brings us all good things is more than just our effort in the outer world — it is a reflection of our inner work and ethical awareness. Leonardo's prayer illustrated this: "Thou, O God, dost sell unto us all good things at the price of labor."
