The sacred cannot be precisely defined. Each of us perceives it through the lens of a unique personal history. For me, sacredness is an experience of the inner radiance of life, the unseen force that transforms and nourishes the physical world but is never limited by it. There is something more to it, a mystery that is never totally grasped.
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."
