"What is love, my friends?" he asked, opening his arms as though he wished to embrace us. "What is love? It is not simply compassion, not simply kindness. In compassion there are two: the one who suffers and the one who feels compassion. In kindness there are two: the one who gives and the one who receives. But in love there is only one; the two join, unite, become inseparable. The I and the you vanish. To love means to lose oneself in the beloved. "
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."
