Inner Planes

[anagogy]

But as for planes in general, just as the physical plane is not owned exclusively by the 3rd density, neither are any of the other planes.

Very cool - so the higher the density, the less limitation and the more options a being has for exploration. Meaning that even in sixth density one may experience something purely physical? Concentrating all of the sixth density energy and focus into the pure physical plane? But of course without a veil.

Yes, every density utilizes all the planes, but as you increase in density level you are then able to use those planes in more finessed or refined ways. They are like notes on a musical instrument. You learn to put them together in more interesting ways, with varying harmonics and artistry.

There are sixth density beings that temporarily manifest entire physical planets and bodies to experience upon them, and then dissolve them the next moment. The higher your density level the more freedom you have to embrace whatever experience you might consciously desire to create. Though many beings at those higher levels have transcended any such desires to experience what we know of as "form", though, some still do. At that level, they mostly reside in time/space but they have a physical realm even there which manifests actual visible light bodies in space/time (though they don't experience the same divisions we do between space and time).
