where is the chakra system located?

this is DISTINCT from the phenomena of dual-activated bodies

I believe in every density transition there would be dual-activated bodies. In this case these are 3.7/4.1. Not fully in 4D, yet not exactly in 3D either, but bridging in between.

Ra mentions specifically that these 'other' 3d bodies can be explored whilst in this density.

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.

I notice there is a great potential of misunderstanding here (I have had great difficulty here too). I don't think that Ra SPECIFICALLY calls these 3rd density bodies. The blue-ray body in this case, is not the yellow-ray body (nor any of 3D's sub-bodies, to be more clear); the blue-ray body is the body of 5th density, properly speaking. The 3rd density body is the yellow-ray body. There are gradients or levels to this 3rd density body, as we have discussed, but it is still a 3rd density body.

If you notice, in that same quote Ra also states: "There are many, many types of bodies in each density, much like your own." Implying that this blue-ray body they were talking about is not a 3rd density body.

Indeed, these "higher" bodies can be explored while in 3rd density, but not exactly IN 3rd density. If you are to activate/use one of your "higher" bodies, you would be momentarily "dislocated," shall we say, from this 3rd density.

This is indeed a very interesting topic/discussion, plenum.
