"And each must learn to travel this Path, each must overcome his own obstacles, unmask his own illusions. Yet there is always the possibility that others may help us do this and, as in the case of Parzival led by Gurnemanz who travelled that Way before, we may be guided in the true Path and taught to avoid the many false byways that may tempt us in our search for the Temple of the Holy Grail. In fact, if our training has been right and our aspiration remains pure, we must inevitably arrive at the end of that Road; often we may seem to do so in the twinkling of an eye, and when we least expect it."
