Separation is a matter of perspective. A room with a person in it can be viewed as one whole, and saying that this room-person is only partially conscious is equivalent to saying that, because my teeth are not conscious and my teeth are part of me, I’m only partially conscious.

Indeed separation is matter of consciousness. If we believe that the universe is more or less a frothing foam of energetic particles, the only thing that differentiates my teeth from my gums and me from the room is my recognition and identification of them. There is matter with or with out me, but there is no room, no tooth, no me without my consciousness.
"[...] the universe is more or less a frothing foam of energetic particles [...]"
"Particles" is plural, implying separation. It that, too, a "matter of consciousness"? Sounds a lot like "consciousness" is being used to do a lot of passing of the proverbial buck.
1. a room and a person in it are separate
2. nothing is separate from the universe
Therefore, there are two things that are not separate from the universe but separate from each other.
