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.
Only as we begin to open to others in love can our isolated ego be transformed. An awareness of our interdependence with other human beings and with all of life provides the environment in which the seed of our souls can flourish.
