You are awareness of the body. The body is not aware, so how can what you are awareness be something that is not aware.
The bodies only existence is because there is an aware knowledge of it. But you are not the knowledge, you are the source of knowledge which is awareness, and awareness is unknown simply because awareness is one without a second...awareness is only known in relation to what it is aware of which is itself of course.
I'm not trying to eliminate you as a body, you cannot be eliminated, you are, without you there is no body...no awareness of body means nothing, and there is no such thing as nothing as you may well know.
You probably abandoned your nonduality study days because of lack of understanding it, this is common, it's very difficult for the mind to grasp it, some people spend their entire life never understanding it...most give up trying...can't say that I blame them really.
But please know this is no reflection on any one here just because they don't get it...the the most important thing to remember is there is nothing to get anyway, it's got you, and you are so loved and precious.
