“Why should he dread to die,” asked Bickley, “seeing that sleep and death are the same?”
“Because his knowledge tells him that Sleep and Death are _not_ the same, as you, in your foolishness, believe, for there Bastin is wiser than you. Because for all his wisdom he remains ignorant of what happens to man when the Light of Life is blown out by the breath of Fate. That is why he fears to die and why he talks with Bastin the Preacher, who says he has the secret of the future.”
“No, Humphrey,” she answered gently. “Because I think that there is no death, and, having done no wrong, I dread no evil. I had dreams while I was asleep, O Humphrey, and it seemed to me that—”
Here she ceased and glanced at where she knew the miniature was hanging upon my breast.
“Now,” she continued, after a little pause, “tell me of your world, of its history, of its languages, of what happens there, for I long to know.”
So then and there, assisted by Bickley, I began the education of the Lady Yva. I do not suppose that there was ever a more apt pupil in the whole earth. To begin with, she was better acquainted with every subject on which I touched than I was myself; all she lacked was information as to its modern aspect. Her knowledge ended two hundred and fifty thousand years ago, at which date, however, it would seem that civilisation had already touched a higher water-mark than it has ever since attained. Thus, this vanished people understood astronomy, natural magnetism, the force of gravity, steam, also electricity to some subtle use of which, I gathered, the lighting of their underground city was to be attributed. They had mastered architecture and the arts, as their buildings and statues showed; they could fly through the air better than we have learned to do within the last few years.
More, they, or some of them, had learned the use of the Fourth Dimension, that is their most instructed individuals, could move _through_ opposing things, as well as over them, up into them and across them. This power these possessed in a two-fold form. I mean, that they could either disintegrate their bodies at one spot and cause them to integrate again at another, or they could project what the old Egyptians called the Ka or Double, and modern Theosophists name the Astral Shape, to any distance. Moreover, this Double, or Astral Shape, while itself invisible, still, so to speak, had the use of its senses. It could see, it could hear, and it could remember, and, on returning to the body, it could avail itself of the experience thus acquired.
