what is the "density" exactly means?

This statement has never made any sense to me:

As the green-ray cycle or the density of love and understanding begins to take shape the yellow-ray plane or Earth which you now enjoy in your dance will cease to be inhabited for some period of your space/time as the space/time necessary for fourth-density entities to learn their ability to shield their density from that of third is learned.

its the point where dimension difference manifests. green/3rd will be different densities, dimensions, much differently (curiously) from how 1, 2, 3d manifests.

Earth has already been 4d in time/space for some time. According to the material, Earth will be 4d in space/time in ~2 years. So green ray will be in full force - but even then, still only "taking shape". Does this simply mean that only at that point would conditions be conducive to nature being able to manifest locally (i.e bodies) in that dimension?

But then yellow ray will not "go into potentiation" at that point? Or, like green ray, will not be available in space/time but in time/space for several years?

Why do 4D entities need to "shield" their whole density from 3rd density? Because it is simply not useful energy?

The analog of electrical energy is interesting. It begs the question of how we are currently using 3d electrical energy, or even 2d electrical energy.
