"I can only tell you, Dr. Silence"—his manner became exceedingly impressive—"that I reached sometimes a point of view whence all the great puzzle of the world became plain to me, and I understood what they call in the Yoga books 'The Great Heresy of Separateness'; why all great teachers have urged the necessity of man loving his neighbour as himself; how men are all really one; and why the utter loss of self is necessary to salvation and the discovery of the true life of the soul."

He paused a moment and drew breath.

"Your speculations have been my own long ago," the doctor said quietly. "I fully realise the force of your words. Men are doubtless not separate at all—in the sense they imagine—"

"All this about the very much Higher Space I only dimly, very dimly, conceived, of course," the other went on, raising his voice again by jerks; "but what did happen to me was the humbler accident of—the simpler disaster—oh, dear, how shall I put it—?"

He stammered and showed visible signs of distress.

"It was simply this," he resumed with a sudden rush of words, "that, accidentally, as the result of my years of experiment, I one day slipped bodily into the next world, the world of four dimensions, yet without knowing precisely how I got there, or how I could get back again. I discovered, that is, that my ordinary three-dimensional body was but an expression—a projection—of my higher four-dimensional body!

Off into my breathless and semi-divine Higher Space! Off, inside myself, into the world of four dimensions!"

He gasped and dropped back into the depths of the immovable chair.

"And there," he whispered, his voice issuing from among the cushions, "there I have to stay until these vibrations subside, or until they do something which I cannot find words to describe properly or intelligibly to you—and then, behold, I am back again. First, that is, I disappear. Then I reappear."

"Just so," exclaimed Dr. Silence, "and that is why a few—"
