"Hearing with the soul" refers to perception with the spiritual senses, to an awakening of a new quality of perception. It is an inbreaking of a contemplative awareness that is capable of perceiving all reality as illumined and suffused by God, as graced with tremendous potential. ...The awakening of the spiritual senses can happen to all of us. We are all capable of "hearing with the soul."
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."
