GRATITUDE is a choice that becomes a habit. It is a major ingredient in the alchemy of transformation and is closely related to love... Gratitude creates a combustion of energy that powers our living cells. That's why all spiritual traditions teach the importance of gratitude. It certainly isn't because the deity needs any reassurance. Rather it's because when we are in the state of gratitude, we're affirming our faith in our own highest good and denying authority to the paralyzing, constricting energy of fear.

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."
