what is the "density" exactly means?

ra describes the 4d material as the material that appears when ectoplasm is produced in a seance.

Ra said the 4d body may be seen by 3d when ectoplasm is produced (in a seance).

second, we are told that the 3d entity would find 4d environments 'very uncomfortable'. not lethal. 4d vibrations are here since 1937, and strengthening. its about to settle this year or so. people are not dropping like flies. one could say that there may not be enough concentration of 4d vibration to cause this, however, in spiritual get-togethers, workshops etc in amiable conditions (positive-feel countryside etc), noticeable energy is produced, and yet, its not causing anyone to die or get crippled, if they are not vibrating in that spectrum. at most, people are finding it very discomfortable and 'weird' or 'eerie', if they are not compatible.

As I said a few times before, in natural conditions 3d and 4d are compatible.

3d entity can manifest ectoplasm, the 4d material, as we are told by Ra.

But we are not told by Ra that ectoplasm is 4d material. It's something that a 4d entity may use to manifest a body in 3d.

the 'spheres' however different. 3d entities do not live with 2d entities, with a few exceptions. 3d sphere and its vibrations are therefore concentrated and manifested where 3d entities are concentrated with vibrations.

now, if we move from here, we can easily understand the 'green and yellow spheres overlap because there are 3-4d entities' concept. currently, there are no different 'spheres', aka concentrations of entities in between 3 and 4d. all entities, 4d activated or not, live together in 3d environments. all the 4d thoughts, feelings going about and 3d thoughts feelings going about fly around in the same time/space.

The sphere is the energy matrix sustained by the earth itself and modified by inhabitants. It exists in both space/time (body/local/material) and time/space (mind/nonlocal/metaphysical). In 3d, the time/space sphere is the concept of the racial memory, morphic field, collective conscious or unconscious, or Noosphere, for example. presumably, the 4d time/space sphere, which has been completed for many years, are where 4d thoughts, memories, and feelings are (morphically) sustained.

The time/space spheres are nonlocal, so distance would not affect individual access. In QM terms, the body is correlated to the 3d and/or 4d time/space sphere at birth.

this, makes the two spheres overlap... if, we separate 4d entities and they start living in separate places than 3d sphere, then there will occur two different spheres, with 4d feelings and vibrations concentrating in different sections of planet, and 3d vibrations again in different sections.

The planet itself creates the entire sphere. The sphere may then be modified by individual or collective consciousness of the same density of that sphere. Right now the 'mind' sphere of 4d already exists in totality.

vibration concentration would make the 4d 'sphere' more fluid, more easy to be affected by 4d vibrations hence more 'controllable' as you put it. and 'lighter'. 3d vibrations, would stay 3d.

Use of will affects the sphere - but the sphere itself is like a nurturing support system and repository for intelligence and memory.
