If there were a feeling associated with the background consciousness that institutes awareness it would be a kind of boredom with the overfamiliar. You are not aware of it because it is constant, and in that it is like your most constant zero-degree of self, what you still have when you have nothing. There is nothing to see because you've seen it all before etc. So you don't notice that this boring accompanying awareness has the peculiar property of being self-grounding, a flat gray layer so that everything else can be built on top of it. It is not to be awakened or changed but appreciated for its radical strangeness.
