We are all strangers in a strange land, longing for home, but not quite knowing what or where home is. We glimpse it sometimes in our dreams, or as we turn a corner, and suddenly there is a strange, sweet familiarity that vanishes almost as soon as it comes... Our homesickness is alleviated only by love, the love that transcends our self-centeredness, our pettiness... When we are truly in love, not in the sense of romantic, erotic love, but in the sense of God's love for all that the Power of Love created, then our homesickness is alleviated. When we are in love we are no longer homesick, for Love is home.
~ from THE ROCK THAT IS HIGHER by Madeleine L'Engle
It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied to a single garment of destiny. Whatever affects one directly, affects all indirectly.
