if i remember correctly (and here i am not certain that i do), daniel ingram has looked to those long-ago first experiences of what he at the time called 'wisdom eye' (owing to an unusual discourse given by the abbot of the temple at which ingram was retreating the night prior to his first experience) as pce's ... which, incidentally, may explain either or both ingram's very quickly acquired facility with inducing pce's (or "pce's") combined with the fact that, a full year since beginning the practice of actualism, he is not yet actually free.

Finishing up my Revised Four Path Model, arahats have finally untangled the knot of perception, dissolved the sense of the center point actually being the center point, no longer fundamentally make a separate Self out of the patterns of sensations as they used to, even though those same patterns of sensations continue. This is a different understanding from those of Third Path in some subtle way, and makes this path about something that is beyond the paths. This is also poetically called the opening of the Wisdom Eye. What is interesting is that I could write about this stage quite well when I was an anagami, but that is a whole different world from knowing it like arahats know it.

The Wisdom Eye may seem to blink initially. It may go through cycles of flashing open just after a Fruition and then slowly fading over a few hours (at least on retreat) as each round of physical sensations, then mental sensations, then complex emotional formations, then lastly fundamental formations such as inquiry itself move through and become integrated into this new, correct and direct perception of reality as it is. Review cycles may occur many times during each flash, but when the eye is open they seem rather irrelevant in comparison to keeping the level of clarity and acceptance high enough to keep the eye open. When the eye fades and the knot of perception seems to retie itself, the familiar insight cycles may seem like pure drudgery, with the focus drifting back to getting lost in the cycles and then gradually shifting again to getting clear enough to get the eye to open again. The themes that occupy center stage go through a cycle that is very much like a progress cycle.

Finally, the Wisdom Eye cycles and insight cycles all converge, and the thing stays open from then on, which is to say that at that point it all seems the same whether or not the eye is open, which it actually was. That being seen, nothing can erode or disturb the centerlessness of perspective, and life goes on. That there are arahats who have opened the Wisdom Eye but had it fade and those who have opened it and had it stay open is rarely mentioned but worth knowing.

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”. That said, insight practices can still be of great benefit to them for a whole host of reasons, there is a ton they can learn just like everyone else about everything else there is to learn. They can grow, develop, change, work and participate in this strange human drama just like everyone else. Practicing being mindful and the rest still helps. They also cycle through the stages of insight, as with everyone above stream entry, so doing insight practices can move those cycles along.

The Simplest Thing is what it has been called here recently. The Simplest Thing is one way of saying those other things. I like the old line, “In the seeing, just the seen. In the hearing, just the heard,” etc. I think it makes its point very clearly and concisely. It doesn’t get any more simple that that, and that was what I realized on that retreat.

I remember the first time I chanced on to No Dog, and it happened to be just a few seconds after the Fruition that got me arahatship. When the mind flipped into that way of perceiving things, it was for me that that time everything I was looking for. As an anagami, I had become so sick of cycles and cycles and cycles that the transcendence of No Dog was absolutely amazing. Cycles occurred, and the only thing of relevance was staying in No Dog. I associated it with the term Wisdom Eye, and my whole goal at that point was keeping in that state. The only problem was it didn’t last...

I do think that No Dog is a very important attainment, just like I like the Formless Realms, The Pure Land Jhanas and Nirodha Samapatti, and No Dog is even one better, but I think that one must finally come to a place where even that is seen as just one more variation or motif on the basic theme that phenomena manifest in various ways and realization must be found in a way that is not bound up in any specifics, and that includes No Dog."

regarding your question about nomenclature, it is uncertain. it is possible that 'mastering the core teachings of the buddha' omits mention of this mode of experience completely, but based on what i've gleaned from recent conversations with daniel, what he refers to the wisdom eye (or sometimes calls 'no-dog' - but this is confusing, as kenneth folk uses that term to mean something else entirely) may be a pce. however, whether or not they are actually one and the same will be easier to determine when the mode of experience he refers to becomes permanent for him.

No dog = Opened third eye

The ego's center is in the solar plexus when it is associated with the body.

The ego's center is in the third eye when it is associated with the bare awareness that proceeds thought/I
