A density is one of seven (or eight, depending on the perspective) dimensions, levels, or cycles of evolution in an octave of experience. It is called a “density” because each successive level is more densely packed with light. As with notes on a musical scale, seven densities are grouped together into an octave where the eighth density begins the first density of the next octave, this repeating infinitely.
Designed by the Logos, every density of experience offers its own set of lessons and parameters that must be learned and understood in order to cross the threshold and graduate from one density to the next. Each density completes its cycle according to the predetermined, clock-like rhythms of intelligent energy.
An alternative term for “density” may be “dimension,” as Ra seemed to use them somewhat interchangeably, but there may be subtle differences between the two terms.
