Me and my big mouth!
Alright, I'm game.
Okay, at the moment, my sense of self appears to be not a single thing, but rather a ragged collection of ideas, images, impressions, opinions, and memories. I understand, intellectually, that there is no entity or object that is the Self. I can pause at any moment during the day, look for a Self, and there is truly never one to be found. And yet there is a strong element that still seems to think that it is the thing that produces those ideas, opinions, preferences, etc. Why?

Well, it was an interesting weekend as I kept up this mode of inquiry, along with regular meditation, while being a groomsman in the wedding of a dear friend. Many mind states to explore and question the reality of the Self, often with a glass of champagne in my hand! So, obviously, I wasn't maintaining laser-like focus on this one issue alone for every moment of the day, but I was very happy to try this way of looking (which is really what it seems to boil down to, in my experience) away from the more quiet, introspective environment of my own home.
I found something that may be of interest to others who come from a Vipassana background who are engaged with this technique. I had to do away with the frequent mental noting that I've become used to in the last year or so in order to really look at the objects around me in a "Self-less" way- just couldn't do the two together. The many things I was noting, on and off the cushion, were so often regarded as part of a story, "my story", even if that was entirely unconscious. This really answers my one big question of noting No-Self/Emptiness in the context of the classical Three Characteristics (Q: "Why is No-Self not always seen clearly?" A: Because there's nothing to be seen." Of course, this is easy to say, but much more tricky to know, in your bones.) So, a big help.
This is not to say that I am not attempting to maintain mindfulness throughout the day, but I feel like my take on it has necessarily matured, and has, in a single leap, become more relevant, useful and organic.
In other regards, I feel like a failure. "Why havn't I popped yet?" "Why does everyone else get it but me?" "Am I really doing this the right way?" It's that last question that may be worth asking. What exactly IS the technique behind this method? What does it really mean to "Look" at the truth? You do it with your eyes, right? Well, that's literally what I've been doing. Just looking at things, and cutting off the discursive mind when it tries to pour back in in a couple seconds time. It takes effort like this.
When I look at the contents of my own mind, the things that make up "Me", I see a closet full of clothes. Interchangable elements, some of which certainly don't fit, or were poorly tailored to begin with, and made of cheap material. The origins of most are questionable, at best. Relatively little is worth a damn. And I can walk away from them at any time, and come back to them- they'll still be there.
Duality, Non-Duality, whatever. Just more concepts to clutter up my closet. I'll throw those two out and see what happens. While still engaged in this method cheerfully, I feel that only in the last day or so have I equally as cheerfully tossed aside my forgone assumptions about what will happen, what it will look like, what it will result in- not just this method, but this LIFE.
