Is possible "jump" a density?

[Verum Occultum]

I found another interesting passage:

So basically one who has penetrated the green-ray body in 3D (time/space) can be harvested to 4th density space/time? And there must be an extremely significant difference between the time/spaces of outer densities compared to the time/spaces of third-density. I am thinking about these quotes by Ra. Notice the bolded parts:

We have the number seven repeated from the macrocosm to the microcosm
in structure and experience. Therefore, it would only be expected that there
would be seven basic bodies which we would perhaps be most lucid by
stating as red-ray body, etc. However, we are aware that you wish to
correspond these bodies mentioned with the color rays. This will be
confusing, for various teachers have offered their teach/learning
understanding in various terms. Thus one may name a subtle body one
thing and another find a different name.

The red-ray body is your chemical body. However, it is not the body which
you have as clothing in the physical. It is the unconstructed material of the
body, the elemental body without form. This basic unformed material body
is important to understand for there are healings which may be carried out
by the simple understanding of the elements present in the physical vehicle.
The orange-ray body is the physical body complex. This body complex is
still not the body you inhabit but rather the body formed without selfawareness,
the body in the womb before the spirit/mind complex enters.
This body may live without the inhabitation of the mind and spirit
complexes. However, it seldom does so.

The yellow-ray body is your physical vehicle which you know of at this time
and in which you experience catalyst. This body has the mind/body/spirit
characteristics and is equal to the physical illusion, as you have called it.
The green-ray body is that body which may be seen in séance when what
you call ectoplasm is furnished. This is a lighter body packed more densely
with life. You may call this the astral body following some other teachings.
Others have called this same body the etheric body. However, this is not
correct in the sense that the etheric body is that body of gateway wherein
intelligent energy is able to mold the mind/body/spirit complex.

The light body or blue-ray body may be called the devachanic body. There
are many other names for this body especially in your so-called Indian
Sutras or writings, for there are those among these peoples which have
explored these regions and understand the various types of devachanic
bodies. There are many, many types of bodies in each density, much like
your own.

The indigo-ray body which we choose to call the etheric body is, as we have
said, the gateway body. In this body form is substance and you may only see
this body as that of light as it may mold itself as it desires.
The violet-ray body may perhaps be understood as what you might call the
Buddha body or that body which is complete.

Each of these bodies has an effect upon your mind/body/spirit complex in
your life being-ness. The interrelationships, as we have said, are many and
complex
Perhaps one suggestion that may be indicated is this: The indigo-ray body
may be used by the healer once the healer becomes able to place its
consciousness in this etheric state. The violet-ray or Buddhic body is of
equal efficacy to the healer for within it lies a sense of wholeness which is
extremely close to unity with all that there is. These bodies are part of each
entity and the proper use of them and understanding of them is, though far
advanced from the standpoint of third-density harvest, nevertheless useful
to the adept.

(47.8)

So those who have explored the regions have explored the inner planes of 3D. Not outer densities. Then Ra said that in the buddhic body lies a sense of being extremely close to all that is. But isn't experience of all that is outer density 7th, really "far away" (meaning you would have to travel through all the outer densities gradually)? I know that words are not the things themselves, and in discussion of such matters they may be heavy misnomers, so I don't interpret them saying or meaning that there is absolutely a "sense of being extremely close to unity with all that there is" versus "being extremely close to unity with all that there is"

This also:  

I am Ra. The heart of the discipline of the personality is threefold.

One, know your self. Two, accept your self. Three, become the Creator.
The third step is that step which, when accomplished, renders one the most
humble servant of all, transparent in personality and completely able to
know and accept other-selves. In relation to the pursuit of the magical
working the continuing discipline of the personality involves the adept in
knowing its self, accepting its self, and thus clearing the path towards the
great indigo gateway to the Creator. To become the Creator is to become all
that there is. There is, then, no personality in the sense with which the
adept begins its learn/teaching. As the consciousness of the indigo ray
becomes more crystalline, more work may be done; more may be expressed
from intelligent infinity.

(74.11)

It seems they are not speaking about the outer 7th density like in the quote below this one.

At the seventh level or dimension, we shall, if our humble efforts are sufficient, become one with all, thus having no memory, no identity, no past or future, but existing in the all.

(16.22)

But then again there is this quote:

As we have noted, each of the true-color densities has the seven energy centers and each entity contains all this in potentiation. The activation, while in yellow ray, of violet-ray intelligent infinity is a passport to the next octave of experience. There are adepts who have penetrated many, many of the energy centers and several of the true colors. This must be done with utmost care while in the physical body for as we noted when speaking of the dangers of linking red/orange/yellow circuitry with true-color blue circuitry the potential for disarrangement of the mind/body/spirit complex is great. However, the entity who penetrates intelligent infinity is basically capable of walking the universe with unfettered tread.

(48.10)

I am a bit confused with these concepts
