what is the "density" exactly means?

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

i didnt want to take it that far, but yes. 4d body may be seen in 3d when ectoplasm is produced. in such seances as described, the entities which were manifesting in those 4d material-shaped bodies have interacted with the seance participants, at least we are told as such. there has been no deaths or dysfunctions reported in any of these seances, due to interaction of a 4d body.

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.

that we dont know. however, i am keeping it low, and assuming that the ectoplasm, which is something that vanishes after the seance, is something related to 4d. in the end, its being produced at the same time with the beholding of 4d body.
