How many songs I have I cannot tell you. I keep no count of such things. There are so manyu occasions in one's life when a joy or a sorrow is felt in suich a way tthat the desire comes to sing; and so I only know that I have many songs. All my being is song, and I sing as I draw breath.... It is just a necfessary for me to sing as it is to breath.
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."
