The Mikmaq on the Atlantic coast have no sound for Nature. They have "space" or "place of creation" ... they have cultural literacy with the ecosystem ... every aspect of nature to Mikmaqs is Spirit. They live in harmony with this intelligible essence. The Mikmaq can perceive the web.
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.
