"Blessed are the pure of heart, they shall see God." A pure heart is utterly simple and focused. It simply wants on thing: to love God with one's whole heart and one's whole mind and one's whole being and to love the other because of the primary love. The pure of heart see the good, want the good for others, and  bring that good to the other. The see God in the other and the good God wants for the other. If our hearts are pure we see through the lens of God's love everything and everyone around us. Strive for this purity of heart in this life and see God in the next.
