In my personal experiences with it, the deconstruction process is not a fall into maddess, but the opposite for me, a fall out of illusionary thought patterns, cessations of extremes, desires and passions, etc. It is just a realization of the objective half of reality, as if going outside looking in. It's through the cultivation and study of silence.

The madness part of the equation, if it happens, comes from going back in the opposite direction, again, where suddenly there are all these....phantoms. Why are they phantoms, because, from the absolute/objective perspective, there's a quality of unrealness, as you head away from zero back to one to two to three, etc, and back around the circle. It's hard to dive back in and accept that which you previously deconstructed as unreal. But you aren't supposed to get stuck there and dwell on it, I don't think. That's just the beginning. You are supposed to see those things as they actually are, not as unreal phantom things, because they are real.

But one of the first things I learned about when I began was the concept of emptying the cup before filling it. That you can't really learn what you think you already know etc. Those are the very things blocking you. It's not about nihilism, though, because you are supposed to fill the cup. It's that point where you have deconstructed as much as you could, that this feeling of light, love, and compassion begins to flood in. Sounds beautiful and blissful right. Except sometimes it isn't. Simetimes its more like some terrible phantom(s) breaking in and shattering your egg/shell, and you'd rather it just go away, and this being is angry and pissed off for being ripped apart and buried.
