The creation has seven levels, or densities; the eighth density forming the first density of the next octave of experience, just as the eighth note of a musical scale begins a new octave. Between seventh and eighth densities the creation re-merges in a period of timeless, formless unity with the Creator. It is Ra’s understanding that “the ways of the octave are without time; that is, there are seven densities in each creation infinitely.”
Third density is the density of self-awareness and the first density of consciousness of the spirit. It is the “axis upon which the creation turns”
Fourth density is the density of love or understanding. Those who have successfully chosen a path come together with others of like mind in what Ra calls a “social memory complex”
Fifth density is the density of light or wisdom. Lessons are often learned individually rather than as a social memory complex. Fifth-density entities are beautiful, by our standards, because they can consciously shape their physical forms.
Sixth density is the density of unity, in which love and wisdom are blended together. The two paths reunite as those on the service-to-self path, realizing that they cannot successfully master the lessons of unity without opening their hearts to others, switch their polarity to positive. Ra is sixth-density;
Seventh density is the gateway density, in which we once again become one with all.
Eighth density is also the beginning of the first density of the next Creation. It is “both omega and alpha, the spiritual mass of the infinite universes becoming one central sun or Creator once again."
