“The visible and the invisible meet at the crossroads which we call our heart. When we say “heart,” we mean that center of our personal being where we are one with ourselves, yet, not with ourselves only. In our heart of hearts, we are one also with all others – all humans, animals, plants, the whole cosmos — and with the Ultimate, with God. St. Augustine affirms from his own mystical awareness a truth of which every human being has an inkling: “In my hearts of hearts God is closer to me that I am to myself.””
