Peace of mind has nothing to do with the external world; it has only to do with our connection with God. Love really is the answer. We're here only to teach love. When we're doing that, our souls are singing and dancing. When we remind ourselves that we are spiritual beings, that life and love are the flame eternal, that's when our soul is nourished.
Love giving itself, losing itself and finding itself in love, and Love returning to itself, giving itself back in love — this is the eternal pattern of the universe. The nucleus throws out its protons and electrons and they circle round it, held by the attraction of Love. Beyond the molecules and atoms, beyond the protons and electrons, there is an energy, a force of life, continually welling up from the abyss of being in god, continually springing up into the light of the Word, continually flowing back to it source in the bliss of love.
