How does Robert Collier use imagery in Secret of the Ages?

Imagery:

"A businessman I know hikes off alone deep into the Maine woods for a week every summer. He neither hunts nor fishes. He arms himself only with knapsack and pup tent. What on earth do you find there? To me he confessed, 'I eat and drink with the Seven Dwarfs. I walk with Hansel and Gretel. And I come out of that wonderful place feeling ten years younger and strong enough in spirit to accomplish anything.'
