“Man lives in a double world: according to the mind he is contained by no physical space and by no walls, but at the same time he is in heaven and on earth, in Italy, in France, in America, wherever the mind's thrust penetrates and extends by understanding, seeking, mastering. But indeed according to the body he exists not, except in only so much space as is least required, held fast in prison and in chains to the extent that he is not able to be in or to go to the place attained by his intellect and will, nor to occupy more space than defined by the shape of his body; while with the mind he occupies a thousand worlds.”

“He was dressed anonymously and had the posture of someone who doesn't know how to occupy the space of his own body.”

“Before man can explore outer space he should first learn to explore the Inner Space of his mind.”

“The trouble with being an angel on Earth was that he was still a man. He got hungry. He thirsted. His lungs clamored without the draw of air. And for this woman, the only one in a thousand years, his body and soul ached. The trick was to will his mind, and ignore the Earthly sensations, as he'd done so many times with pain and trouble. Desire was no different, a call of the flesh. He could divide himself-acknowledge the lust and act on intellect. But see, the trouble with being an angel was that he was still a man.”

“Thinking no more about it, he stepped off into that cool space, that fast descent to her, with nothing in his mind but a memory of a curve of her shoulder, naked, as he had never seen it.”

“He left the room, and closeted himself in the dark, buzzing space where he raised his wasps and plotted the courses of heavenly bodies.”
