First this is what the material says about Edgar Cayce:
14.31 Questioner: The Edgar Cayce material. Who spoke through Edgar Cayce?
Ra: I am Ra. No entity spoke through Edgar Cayce.
14.32 Questioner: Where did the information come from that Edgar Cayce channeled?
Ra: I am Ra. We have explained before that the intelligent infinity is brought into intelligent energy from eighth density or the octave. The one vibratory sound complex called Edgar used this gateway to view the present, which is not the continuum you experience but the potential social memory complex of this planetary sphere. The term your peoples have used for this is the “Akashic Record” or the “Hall of Records.” This is the last question which you may now ask.
65.9 Questioner: We would seem to have dual catalysts operating, and the question is which one is going to act first. The prophecies, I will call them, made by Edgar Cayce indicated many Earth changes and I am wondering about the mechanics of describing what we call the future. Ra, it has been stated, is not a part of time and yet we concern ourselves with probability/possibility vortices. It is very difficult for me to understand how the mechanism of prophecy operates. What is the value of a prophecy such as Cayce made with respect to Earth changes with respect to all of these scenarios?
Ra: I am Ra. Consider the shopper entering the store to purchase food with which to furnish the table for the time period you call a week. Some stores have some items, others a variant set of offerings. We speak of these possibility/probability vortices when asked with the understanding that such are as a can, jar, or portion of goods in your store.
It is unknown to us as we scan your time/space whether your peoples will shop hither or yon. We can only name some of the items available for the choosing. The, shall we say, record which the one you call Edgar read from is useful in that same manner. There is less knowledge in this material of other possibility/probability vortices and more attention paid to the strongest vortex. We see the same vortex but also see many others. Edgar’s material could be likened unto one hundred boxes of your cold cereal, another vortex likened unto three, or six, or fifty of another product which is eaten by your peoples for breakfast. That you will breakfast is close to certain. The menu is your own choosing.
The value of prophecy must be realized to be only that of expressing possibilities. Moreover, it must be, in our humble opinion, carefully taken into consideration that any time/space viewing, whether by one of your time/space or by one such as we who view the time/space from a dimension, shall we say, exterior to it will have a quite difficult time expressing time measurement values. Thus prophecy given in specific terms is more interesting for the content or type of possibility predicted than for the space/time nexus of its supposed occurrence.
less relevant to the topic:
The vortices for earth changes of that magnitude Cayce talks about did not materialize as described. After all, they were possible/probably at the moment.
In my opinions these did not materialize due to the massive influx of wanderers...60 million or so circa 1981:
However how about others: look at BRICS and Russia and what Cayce said:
In Russia there comes the hope of the
world, not as that sometimes termed of
the Communistic, of the bolshevistic; no.
but freedom, freedom! That each man
will live for his fellow man! The principle
has been born. It will take years for it to
be crystallized, but out of Russia comes
again the hope of the world. Guided by
what? That friendship with the nation
that hath even set on its present monetary
unit “In God We Trust.”
And we already know Russia received technology from the Confederation after Stalin's death. Meaning, seems logical that positive oriented philosophy was given along technology.
