The system of densities that the evolving entities and social memory complexes move through takes place within a larger cycle known as an octave. Each octave contains seven densities with the eighth density being the first density of the following octave. Each octave is a heartbeat that births a new universe which begins with first density and is absorbed again at the eighth density. That which is learned in one octave is carried forward in the next. Acknowledging limitations upon their knowledge, Ra assumes that there are an infinite number of octaves, the ways of the octave being without time; that is, there are seven densities in each creation, infinitely.
As the creation can be seen to have some fractal characteristics, Ra sometimes refers to individual densities, sub-densities, or even certain cycles of experience, as octaves. Octave is also synonymous with the terms universe and creation.
