The theme of the Grail is the bringing of life into what is know as the wasteland. The wasteland is the preliminary theme to which the Grail is the answer. What is the sense of the wasteland? It's the world of people living inauthentic lives. If there is a path, it is someone else's path and you are not on the adventure. Each entered the forest at a point that he himself had chosen, where it was darkest and there was no path.
