Everything which comes into being in time has its origin in the eternal. But the eternal is not accessible to sensory perception. Nevertheless, the ways to the perception of the eternal are open for man. He can develop forces dormant in him so that he can recognize the eternal. In the essays, Wie erlangt man Erkenntnisse der hoheren Welten? (How Does One Attain Knowledge of Higher Worlds?), which appear in this periodical, (*) this development is referred to.
These present essays will also show that at a certain high level of his cognitive power, man can penetrate to the eternal origins of the things which vanish with time. A man broadens his power of cognition in this way if he is no longer limited to external evidence where knowledge of the past is concerned. Then he can see in events what is not perceptible to the senses, that part which time cannot destroy.
He penetrates from transitory to non-transitory history. It is a fact that this history is written in other characters than is ordinary history. In gnosis and in theosophy it is called the “Akasha Chronicle.” Only a faint conception of this chronicle can be given in our language. For our language corresponds to the world of the senses. That which is described by our language at once receives the character of this sense world. To the uninitiated, who cannot yet convince himself of the reality of a separate spiritual world through his own experience, the initiate easily appears to be a visionary, if not
The one who has acquired the ability to perceive in the spiritual world comes to know past events in their eternal character. They do not stand before him like the dead testimony of history, but appear in full life. In a certain sense, what has happened takes place before him.
