It's already a part of you.
"Easy for you to say. But how come I can't tell that it's already there?"
Because your awareness is unrefined.
Your awareness has become too gross. You've long ago decided that listening to other voices in your head were simply more important. So you implicitly chose to stop being aware of the underlying field of consciousness--you gave it up in exchange for mind-based distractions. And your awareness, which was a very fine thing, instead became blunt and gross.
"Surely you're joking."
No, not at all. It's as simple as that.
"Okay, so how do I refine my awareness back to become aware of consciousness again?"
What you're missing is daily, regular meditation, which has as its goal the refining of awareness of consciousness.
"So then I'd be aware of consciousness?"
Yes, absolutely. Because it's in you already.
