The earth needs people who can say, "Yes there is more." Not just more in the way of knowledge or inventions or wisdom or revelations, but more compassion, more gentleness and sweetness, more caring, more love, more valuing of one another. That is your mission, and it is of the highest, for it is nothing other that the mission of manifesting the spirit of the Beloved in your life.
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.
