6D - 7D Mysteries

[anagogy]

It's odd how Ra mentions the system of 7 is the best system found so far.  It was 'found out', as if to say the Creator didn't design it but just found it present to work with.

The system of 7 being the best or most efficient found was in reference to the archetypes, I believe.  The seven vibratory densities in an octave is, instead, something Ra stated was inherent in infinity.  Perhaps the system of seven archetypes for the mind. body, and spirit was best because it lined up with that particular cosmic aspect or truth.

Personally, I would caution against too much complexity.  

I can't see any purpose or reason in more than seven densities, and Ra said nothing of the sort.  I mean you could argue that Ra doesn't have the whole picture, but then, we are that times infinity because we are hunks of 3rd density meat...
