The "mysterious exchange of gifts"

"To feel the love of people whom we love is a fire that feeds our life. But to feel the affection that comes from those whom we do not know, from those unknown to us, who are watching over our sleep and our solitude, over our dangers and our weaknesses—that is something still greater and more beautiful because it widens out the boundaries of our being, and unites all living things."
— Chilean poet Pablo Neruda
