[…] After a while, and it can vary for different people, one will have gone through many cycles—with what will appear to be an underlying cycle beneath these surface cycles. When the underlying cycle comes to completion, the surface cycles and deeper cycle converge with a fruition, and there is a dramatic shift in perception where one begins to see what is meant by emptiness, now in real-time. This shift, which is the 3rd stage of enlightenment, has to do with seeing the empty, selfless nature of reality upon mere reflection. Where once emptiness was contained in the discontinuity experience at the end of an insight cycle, it now permeates all of experience. It comes obvious, for those of 3rd path, what is meant by the lines from the Heart Sutra, “form is emptiness.”
The time between 3rd path and 4th path tends to be the longest yet. Ingram breaks 3rd path into early and mature phases. In the early phase one is still looking for the cycles to bring further progress, whereas in the mature phase emptiness is so ordinary and integrated into one’s experience that the inquiry turns away from the cycles and toward the last subtle hints of duality, which remain.
Finally, there is another radical shift in perspective, in which the sense of a separate center-point, observer, or doer is completely undone. Apparently this realization can occur and then fade for some time, until finally the shift is permanent (i.e. nothing can interrupt this centerless perspective). This is the opening of the “wisdom eye”, the attainment of arhantship, and as Ingram says is the end of insight path: “For the arahat who has kept the thing open, there is nothing more to be gained on the ultimate front from insight practices, as ‘done is what is to be done’.” It’s also interesting to note that it’s difficult to predict how long it will take from 3rd to 4th path. It tends to be the longest path, though I have so little data (even anecdotal) that it’s really hard to say. […]
I am especially intrigued by this part:

From my own (always) limited experience, it seems that an aspect of this phase has to do with recognizing even the remaining sense of a center/I-other as a gestalt, and also as emptiness/awakeness itself. When attention is brought to it, it is recognized as a gestalt made up of sensations (for me, in the head area) and a set of mental field images (center-periphery + a “doer” in, around or above the head), and the sense of substance or reality of the gestalt fades or falls away. Also, even at the gestalt level, it is all directly recognized as emptiness and awakeness itself.
And in that recognition, the tendency to resist it tends to fade or fall away as well. It is all seen as OK as is, even if there is a sense of center there, because that too is emptiness itself.
This also fits what Mike Snider said about his own path in one of his talks. For many years, there was a oneness state, recognizing all as God yet with a sense of “me” (center, observer, doer) hanging around. Then, a period of shifts between this sense of me falling away and returning. Then a recognition that it is all emptiness/awakeness itself, whether there is a sense of me there or not. And finally (he didn’t say this, but I assume this is what happened), a clearer recognition and more familiarity with this.
