To really love is a great discipline, because we must love stably and consistently and regardless of whether or not our love is returned. In other words, we love despite our likes and dislikes, despite our selves or egos. We simply ALLOW love to be a transformative force in our lives. ALLOWING is the key. And this is not a passive but an active discipline... Genuine love asks for nothing in return, through it always works toward duplicating itself in others. Thus, the greatest reward for one who practices the discipline of love is that another being has been illumined by that love and is now carrying that gift to others.
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."
