Continuance (and probably some conclusion) on densities

[unity100]

@Unity100... I guess my issue is not with the idea that our 3D self will die; my questions are more in regards to what it means in respect to the complete picture. Why does Ra make it very clear each time he is speaking of the yellow sphere specifically? He mentions no end of the red or orange spheres in any way, and differentiates the yellow from the green as a difference of perception? An inability to understand the world without the 4D lens is what will end the 3rd density, according to that quote. Take this part for example:

This transitional body is one which will be, shall we say, able to appreciate fourth-density vibratory complexes as the instreaming increases without the accompanying disruption of the third-density body. If a third-density entity were, shall we say, electrically aware of fourth-density in full, the third-density electrical fields would fail due to incompatibility.

at the end of the very quote, ra says the 3-4d bodies will die according to the necessities of 3d.

Additionally, I feel like Ra is being too straightforward with their handling of death. I have found in my own readings that Ra seems to be almost "catalytic" in thier discussion of death throughout the LOO. They know that death/mortality is our issue; the one thing we really can't get over. For this reason, I get the feeling Ra is challenging us by giving us a very bleak-sounding scenario. However, as we are warned, trust nothing that brings fear, and that's why I question some sort of terrible end to us

what you perceive as 'terrible' is just death, which has happened to all of these people over and over and over and over endless times from 1d to this late 3d life up until now. even when in 4d, there is still life and death, in 5d, there is still life and death, and in 6d, there is still life and death - then only in 7d it stops, with the stopping of reproduction because 'the need to reuse body complexes end'.

its this society's perception that makes death 'terrible' for them.

ra sees this as something that is just trivial, transient and normal. this is explicitly stated even regarding the earth changes, and it is dubbed as 'conditions that bring harvest'.
