What is the Akasha Chronicle? We can form the truest conception of it by realising that what comes to pass on our earth makes a lasting impression upon certain delicate essences, an impression which can be discovered by a seer who has attained Initiation. It is not an ordinary but a living Chronicle. Suppose a human being lived in the first century after Christ; what he thought, felt and willed in those days, what passed into deeds — this is not obliterated but preserved in this delicate essence.
The seer can behold it-not as if it were recorded in a history book, but as it actually happened. How a man moved, what he did, a journey he took-it can all be seen in these spiritual pictures; the impulses of will, the feelings, the thoughts, can also be seen. But we must not imagine that these pictures are images of the physical personalities. That is not the case.
To take a simple example. — When a man moves his hand, his will pervades the moving hand and it is this force of will that can be seen in the Akasha Chronicle. What is spiritually active in us and has flowed into the Physical, is there seen in the Spiritual.
Suppose, for example, we look for Caesar. We can follow all his undertakings, but let us be quite clear that it is rather his thoughts that we see in the Akasha Chronicle; when he set out to do something we see the whole sequence of decisions of the will to the point where the deed was actually performed.
To observe a specific event in the Akasha Chronicle is not easy. We must help ourselves by linking on to external knowledge. If the seer is trying to observe some action of Caesar and takes an historical date as a point of focus, the result will come more easily. Historical dates are, it is true, often unreliable, but they are sometimes of assistance. When the seer directs his gaze to Caesar, he actually sees the person of Caesar in action, phantom-like, as though he were standing before him, speaking with him. But when a man is looking into the past, various things may happen to him if, in spite of possessing some degree of seership, he has not entirely found his bearings in the higher worlds.
