No worries!

Me too. In fact, I suspect you already know all this stuff and you think you're getting preached to. I'm just adding to the thread in a generic way, because I know there are other people who are probably interested in the subject. (I tend to use the generic "you" and "we", but I'm realizing it sometimes gets interpreted too specifically or too vaguely... I need to figure out how to say things better.) Anyway... more babbling on this topic below...
Moments of awareness can definitely go from narrow to broad. Knowing is always a knowing "of" something, therefore locational. All of these aspects of experiencing are good to tease out.
Whenever we just sit and notice the way we look at the world, it alternates between a center or edge framing. As we "look out our eyes", if the mind goes into the midst of the view, then it seems like awareness is like a container that is holding all the individual objects within the view. If we notice the edges of the field of view, then it seems like the self/body is where awareness resides and all objects appear in "our" vision. Both of these views are created by "attention" which is a selective aspect of mind. You could say that it's driven by either a desire to "know" or "to exist". When we want to "know" the world then attention goes to the center of the field. When we want "to exist" the attention goes to the edge of the field.
If attention/control/manipulation is dropped (which usually requires work on momentary "surrendering" to what occurs) then both the center and the edge can be seen together, which is basically the desireless "rigpa" or non-dual experience. As soon as a desire comes to "have" the rigpa experience, attention comes on line and it becomes the center or edge view again.
The interesting thing is that "rigpa" or non-duality itself can be known, it can be recognized as an experience. People can substitute every day samsara (trying to chase pleasure, and avoid pain) with a kind of spiritual samsara (trying to chase non-duality, trying to avoid non-duality) --- which is fine if it is an intentional act, but it is also subject to reinforcing spiritual craving and ill will for the world.
The spiritual urge is driven by a sense of fundamental lacking in the moment. Spiritual progress gives a little fix of the pride of attainment, but there is always more experiences to have... so it can be just a fancy form of suffering.
By the time someone accesses the non-dual view, it can be a good time to search around for the fundamental sense of lacking, needing, and ill will. All beings have it, it's so subtle, but drives us all crazy. To find it requires just letting the "attention" of the mind do it's thing, so that we can notice it for what it is. It's a kind of momentary surrender practice that doesn't mean you give up having control in life, just that for the sit you don't try to change a thing.
So the challenge then becomes, what is this urge that tries to change things in the moment? It's a different kind of investigation than looking for events in awareness. It's looking at the intentional quality of attention. This is where the sense of self lies, as well. Self exists because there is a problem to fix, there is always a problem to fix it seems. But when the self is seen, that "there's always a problem to fix" compulsion is seen for what it is.
There is an awakening to no-self or true-self, which has a sense of "Oh, this is it. The world is this." And the tiniest form of suffering is dropped, but it seems to make a big difference, even if it's equally true that nothing really changes.
