Burrowed in the foothills of the Canadian Rockies is a wooden house, a retreat center made of pine and spruce and filled with mushroom carvings, tapestries of periwinkle and indigo paisley, books about “The Indoctrinated Brain” and other paraphernalia nodding to the promised transformation: Enter as a chief executive, emerge as an enlightened one..
