Let me welcome fear for the friend it is, for what it teaches and how it serves. When I feel the hairs on the back of my neck bristling for no reason, when I sense an unexplainable tremulousness, I never again want to deny it or call it neurotic. Instead, I want to welcome it, go into it, see what it is trying to show me. (Gerald G. May, The Wisdom of Wilderness Experiencing the Healing Power of Nature)
