"Whenever we touch nature we get clean. People who have got dirty through too much civilization take a walk in the woods, or a bath in the sea... They... allow nature to touch them. It can be done within or without. Walking in the woods, lying on the grass, taking a bath in the sea, are from the outside; entering the unconscious, entering yourself through dreams, is touching nature from the inside and is the same thing, things are put right again."
~ C.G. Jung
