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.
We need to sit still, let our emptiness remain empty, and wait patiently. If we fill the foreground with busy questions, reasons or proposed actions, we will miss the God who is the silent, yet ever present horizon of the world.
