"The higher dimensions are being conquered.
Nearly all of us can pass into the fifth at will, 'disappearing,' as you have the word." Was it possible that in the vanishing of the pursued car this had been demonstrated before him?
Into this space, inclusive of the visible world and of Yaque as well, had the car passed _without the pursuers being able to point_ to the direction which it had taken?
St.George smiled in derision as this flashed upon him, and it hardly held his thought for a moment, for his eyes were upon Olivia's face, so near, so near his own ...

Undoubtedly, he thought vaguely, that other motor had simply swerved aside to some private opening of the grove and, from being hard-pressed and almost overtaken, was now well away in safety.

But to that strange and unapparent hyperspace they could not have taken her, because she did not understand.

"...just as one," Prince Tabnit had said, "who understands how to die and come to life again would not be able to take with him any one who himself did not understand how to accompany him..." Some terrifying and exalting sense swept him into a new intimacy of understanding as he realized glimmeringly what heights and depths lay about his ceasing to see that car of the guard.
