astral sphere

Composed of ethereal material or non-physical (sometimes supersensible), and capable of sometimes separating from the physical body (as an astral body) to travel to other places or to other realms of existence (in or via the astral plane).

In the case of an inanimate body, […] when the physical object was broken the astral counterpart would also be divided; but it would not be possible to break an astral counterpart, and in that way to affect the physical object. In other words the act of fraction must begin on the physical plane. One could of course move a purely astral object by means of an astral hand if one wished, but not the astral counterpart of a physical object. In order to perform this latter feat it would be necessary to materialize a hand and move the physical object, when the astral counterpart would of course accompany it.

"[I could] see her astral form sitting on the edge of her bed. She was waiting for me."
