FDR left a handwritten speech in a drawer when he died (to deliver at the UN). He wrote, "If civilization is to survive, we must cultivate the science of human relationships—the ability of all peoples, of all kinds, to live together and work together, in the same world, at peace... The only limit to our realization of tomorrow will be our doubts of today. Let us move forward with strong and active faith."
Divine peace has an inner and outer manifestation. Exteriorly, it manifests as fire, as zeal, as transformation, as death and rebirth. Interiorly, it manifests as silence, as knowledge, as joy, as union with the Beloved: a joy of union that is capable of communicating itself to others.
