Every person has a share in this world and a share in the world to come. We understand the concept of a share in the world to come, but what does it mean having a share in this world? Open your hearts. Having a share in this world means I know exactly what I have to do in this world. This is a very high level. If I know that if I don't do it, it just won't happen. Then I've just got to do it. This is my share in this world.
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."
