This is not for anyone advanced but perhaps for those who are confused a bit about what this awareness "thing" is and where it resides. In any case I think this contemplation brings a certain clarity and helps with self inquiry. To be honest, they do say that having a beginner's mindset is very important, so perhaps this is for everyone.  We all know we are humans in time, with different stories and whatnot.. With past and future. A materialist might say this. I agree from one perspective that is the case. But ok now, that's not interesting, let's go into another dimension now, rather than the horizontal dimension of time. Lets go further and deeper into this moment right now, the vertical dimension, to see what we actually are at this moment and not what we are in the story of time. Here, now, we can see that there are different sensations, perceptions, feelings, thoughts, sounds, sights, etc etc... All subjective objects of experience.  All of those different objects have something in common, right? They might be completely different - sound and thought,  sight and touch.. But they are all happening to you, correct? All happening in the field of your awareness,  otherwise you wouldn't know about them, So the common thing in all objects of experience is you. You are that unifying thing. What could this be?  Inquiring into that self which unifies all objects of experience now is what true self inquiry is. If you are doing self inquiry,  but at the same time look at yourself as the human in time, your self inquiry will yield wrong results, since all stories and all time are just another one of those subjective objects that appear to you (as the unifying awareness) Now.  Not sure this makes sense to others but I see in this a lot of clarity and I was able to get my friend who is fanatical about time and very egoic to see for the first time that I am not talking just crap when I speak about the true self, but there is really something interesting there to investigate. It was a real breakthrough, so it might help someone else who is stuck also.  Ps: I noticed that acknowledging his worldview is correct in one perspective helped for him to be open to entertain something else. Perhaps this thread can also be about how best to share and present nonduality to people who are worshipping duality and wouldn't even hear it.
