Is possible "jump" a density?

[Infinite]

So basically one who has penetrated the green-ray body in 3D (time/space) can be harvested to 4th density space/time?

Second Q'uo the inner plans (astral, devachanic, causal, etc. or dimensions fourth, fifth, sixth, etc.) are part of 3D and not from other density. But, there is an energetic relationship between these plans and the densities. For this reason, the beings of others planets come to Earth and express yourself in dimensions compatible with your density. Remembering that density is a vibrational frequency and dimension a location.

One who has activated the green ray become harvestable but when go beyond and work with the indigo ray can penetrate a lot of planes. As I quoted above :

50.8 Questioner: Thank you. How does the ability to hold visual images in mind allow the adept to do polarization in consciousness without external action?

Ra: I am Ra. This is not a simple query, for the adept is one which will go beyond the green ray which signals entry into harvestability.The adept will not simply be tapping into intelligent energy as a means of readiness for harvest but tapping into both intelligent energy and intelligent infinity for the purpose of transmuting planetary harvestability and consciousness.

The means of this working lie within. The key is first, silence, and secondly, singleness of thought. Thusly a visualization which can be held steady to the inward eye for several of your minutes, as you measure time, will signal the adept’s increase in singleness of thought. This singleness of thought then can be used by the positive adept to work in group ritual visualizations for the raising of positive energy, by negative adepts for the increase in personal power.

Well, this is my vision:

There is an great octave. Within this octave there is 7 quantum or octave which we call density, being the itself octave the eighth density. Within each density there is 7 sub-densitities and thus successively to infinite. I believe that the inner planes can be sub-densities of third density. In the fourth and fifth density probably exist inner plans also for the space/time and time/space exist until sixth density, the last density of duality or polarity.
