To create from joy, to create from wonder, demands a continual discipline, a great compassion. It demands a severity of mind towards all vanity and posturing of the ego that loves its suffering, and clings to its despairs and depressions and fears; it demands a continual objectivity of spirit, a continual looking out at, and beyond, the world created by the senses, towards a spiritual reality, whose lineaments only emerge slowly, after years of experience and meditation. You do not need to stop working, but you need to strive for a new relationship with your work... With time and sincerity you will discover a way to work that does not harm you spiritually, does not tempt you to vanity, that is the deepest expression of your spirituality.
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."
