Religion is a more or less organized way of remembering that every Mystery points to a high reality. A reality overarching and infusing this world with splendor. One pulsing through its veins. Unnoticed and unnamed. Of the Nameless One. A holiness so holy that it fills even our everyday illusions with spiritual meaning.
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.
