If you wish to love you must learn to see again...You must tear away from your being the roots of society that have penetrated to the marrow. You must drop out. Externally everything will go on as before, you will continue to be in the world, but no longer of it...And in your heart you will now be free at last and utterly alone...There is no one there by your side, absolutely no one. At first it will seem unbearable, but that is only because you are unaccustomed to aloneness. But if you manage to stay there for a while the desert will suddenly blossom into Love.
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."
