All of these exact questions are answered by continuing further into the Ra material, Don follows more or less your exact question intentions. Previous posts do a great job, and I just want to throw some extra quotes on one of the questions as a taste, some quotes might be duplicated here so sorry about that.
Question 4:
Question 4:
Quote:This octave density of which we have spoken is both omega and alpha, the spiritual mass of the infinite universes becoming one central sun or Creator once again. Then is born a new universe, a new infinity, a new Logos which incorporates all that the Creator has experienced of Itself. In this new octave there are also those who wander. We know very little across the boundary of octave except that these beings come to aid our octave in its Logos completion.
Quote:Ra: I am Ra. This is basically correct. However, it is well to perceive that the eighth density functions also as the beginning density or first density, in its latter stages, of the next octave of densities.

81.18 Questioner: Why does Ra not have any knowledge of that which was prior to the beginning of this octave?
Ra: I am Ra. Let us compare octaves to islands. It may be that the inhabitants of an island are not alone upon a planetary sphere, but if an ocean-going vehicle in which one may survive has not been invented, true knowledge of other islands is possible only if an entity comes among the islanders and says, “I am from elsewhere.” This is a rough analogy. However, we have evidence of this sort, both of previous creation and creation to be, as we in the stream of space/time and time/space view these apparently non-simultaneous events.
Quote:78.15 Questioner: Then the first experiences, as you say, were in monochrome. Now, was the concept of the seven densities of vibration with the evolutionary process taking place in the discrete densities— was that carried through from the previous octave?
Ra: I am Ra. To the limits of our knowledge, which are narrow, the ways of the octave are without time; that is, there are seven densities in each creation infinitely.
Quote:Ra: I am Ra. At the beginning of this creation or, as you may call it, octave there were those things known which were the harvest of the preceding octave. About the preceding creation we know as little as we do of the octave to come. However, we are aware of those pieces of gathered concept which were the tools which the Creator had in the knowing of the self.
