All the Octaves are built on top of each others and since it is all happening within an eternal present, many also interpenetrates each others. But the "complexities" of an Octave comes from integrating the harvest of the previous ones.
Big Bang and Big Crunch. Then another cycle, another Big Bang and Big Crunch. So on and so on. While each iteration makes use of what was learned on the previous cycle.
Quote:28.16 Questioner: Are you saying then there are an infinite number of octaves of densities one through eight?
Ra: I am Ra. We wish to establish that we are truly humble messengers of the Law of One. We can speak to you of our experiences and our understandings and teach/learn in limited ways. However, we cannot speak in firm knowledge of all the creations. We know only that they are infinite. We assume an infinite number of octaves.
However, it has been impressed upon us by our own teachers that there is a mystery-clad unity of creation in which all consciousness periodically coalesces and again begins. Thus we can only say we assume an infinite progression though we understand it to be cyclical in nature and, as we have said, clad in mystery.
