Correspondence Between Densities and Traditional Planes of Existence

[anagogy]

Is the 2nd density of the next octave "beyond" infinity? Or is it a whole nother infinity?

Neither. It is the same infinity (there's only one infinity--unity contains all). It is always the same infinity, just a different refraction of the light of that infinity. One white light being filtered through a different prism each time, which distorts it into the seven rays. Rays are essentially "types" of experiences, or perspectives of consciousness available in infinity. So any creation, or exploration of light, is going to fall into one of those "categories".

The 2nd density of the 'next octave' is simply another focus, or crystallization, of orange ray, or lower astral consciousness (personal consciousness). Every octave is another manifestation of the same rays, but the specifics of how they crystallize will be different. So every octave is going to have a physical/astral/mental/causal/buddhic manifestation. They are simply the natural continuum between the formless and the formed, the intangible and the tangible. The actual forms themselves will be unique, however, just as every snowflake has similar characteristics but is ultimately unique.

2nd density is identification with orange ray, which becomes the perspective, or filter, through which the other rays are then interpreted. So a 2nd density being will see physicality through the eyes of orange ray, and will see the lower astral through the eyes of orange ray, it would see the middle astral through the eyes of orange ray, and so on up the rays. Your density level, or ray that you are identified with, colors everything you perceive to "fit in" to that particular interpretation of reality.
