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.
Faith means receiving God, it means being overwhelmed by God. Faith helps us to find trust again and again when, from a human point of view, the foundations of truth have been destroyed. Faith gives us the vision to perceive what is essential and eternal. It gives us eyes to see what cannot be seen, and hands to grasp what cannot be touched, although it is present always and everywhere.
