Love all the earth, every ray of God's light, every grain of sand or blade of grass, every living thing. If you love the Earth enough, you will know the divine mystery.
Peace always begins within each of us. Our ability to create in the world depends on our ability, first, to work to create peace in our own lives. It's much easier to advocate peace on Earth than it is to be able to bring peace your own home. Or your own heart.
