There are times not to answer the door, not to answer the phone, not to do undone things, but to rest in silence from everything. The world can wait for five minutes. In fact, no matter how busy we are, no matter how well organized, no matter how little rest we allow ourselves, we will never do all that needs to be done. But to do well what we are called to do, it is essential to nurture a capacity for inner stillness; such quiet, deep-down listening is itself prayer.
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."
