In his chapter on the shadow in Integral Spirituality, Ken Wilber writes about the me and mine, and the you and it, within transcend and include as it shows up in spiritual practice.
Arising as 1st, 2nd and 3rd person
Anything arising can be seen as 1st, 2nd or 3rd person: as I, me or mine, as you, we or ours, or as it, other or theirs's.
Trancend and include
And anything arising can be transcendet and included through various forms of spiritual practice such as meditation and self-inquiry. It arises within the field of everything arising in the present. And it arises as awareness, consciousness, Spirit, Buddha Mind, Brahman, God. This is of course wonderful in itself. It is reality waking up to itself.
From a blind identification with content, with the seen such as our human self or our soul, the center of gravity and identity shifts into the seeing itself, as the witness the seen arises within and to and as. And from here it shifts into realizing that there is no I anywhere in all of this: here is no I in the seen and no I in the seeing. The center falls away. The self-contraction falls away. There is just a field of what is, of the seen and the seeing, absent of I anywhere.
And there is the realization that this is how it always already is, even in the midst of the temporary misidentification with a portion of the seen or with the seeing itself.
Yet, as KW points out, there is a very important differentiation here. There are two flavors possible for what has been transcendet and included.
The me, you and it of that which is transcendent and included
If it is recognized and known as I, it becomes me and mine. It is arises as you or yours, or it or theirs, then it remains so even after the transcending and including of it.
In the first case, it remains 1st person. In the second case, it remains 2nd or 3rd person. Even as it arises as Buddha Mind, Spirit, emptiness dancing.
Example: anger remains an it
This is something I saw clearly in my initial awakening in my teens, and one of the reasons I worked so much (and still do) on recognizing and integrating projections: making the it into I and mine. It is a long process, one that lasts as long as there is a functional connection with a human self, so it is a good thing to find peace with - and find the enjoyment in.
For me, anger was definitely an it, an yours and theirs, probably due to the long list of typical suspects such as upbringing, family and cultural patterns, my young age (not ready to wake up from this aspect of the family and cultural trance), and so on.
So even in the midst of the awakening, where everything is revealed as consciousness, as Spirit, as God, it remained an it. Anger arises as Buddha Mind, with no separation and even with no I anywhere. Yet also firmly as an it to this human self, within all of that.
As Spirit, there is of course no need to integrate it. It already naturally is, arising within and as Ground and Spirit.
Yet on a human level, for this human self, it was very different. This human self had no idea of to integrate it, how to include it in its repertoire, how to use it, how to live it, how to use its energy in daily life and interactions with others, how to effectively relate to it when it comes up in in oneself or others. Anger remained an it. Something slightly foreign to this human self.
If anger is an I or mine previous to the awakening, it looks quite different. Of course, it still arises as Spirit and Buddha Mind. But it is now me and mine when it arises. It is not foreign to this human self, but something familiar, something that is included in the repertoire, something that can be lived and used in daily life, something that this human self knows how to relate to in itself and others in daily life - in a more effective and effortless way.
The absolute and relative of me and yours and it
At the absolute level, there is no difference. It arises as Buddha Mind and that's it.
At the relative level, there is a huge difference. In the one case, where it remains an it, it is left out of the repertoire of this human self. It is foreign to this human self. And in the other case, it is included in the repertoire, it is familiar, it is a tool that this human self knows how to relate to and use.
Never too late...!
Of course, it is never too late to make the it into a mine, to own that which was disowned, to become more familiar with it at a human level, to include it into the realm of the familiar and the daily repertoire of this human self.
Gradations along the scale of 1st, 2nd and 3rd person
And there are also, of course, gradations of this, all the way from extreme disowning of the quality at a human level, to a deep familiarity and comfort with it. It can be something that this human self never touches, even after awakening. Or it can be something it is very familiar with as mine and knows how to use with elegance and effectivity.
These qualities are not only a component of our human makeup, allowing us to be fuller, richer and more complete and mature human beings. They are also skillful means, and the more of them that go from yours and it into me and mine, the larger the repertoire of skillful means available to us.
Deepening in familiarity, fullness and richness
There are always more of the yours and it that can be made into me and mine. And there is always further to go in allowing this human self to become familiar with it, exploring how to use it, how to live it, how to bring it seamlessly into daily life.
It can deepen in richness and fullness, as a me and mine.
How to work with this
In terms of the techniques for working with this that I am familiar with, the Big Mind process and The Work both seem excellent.
Through both, we become familiar with the its as me and mine. We learn to own that which was previously disowned. To include in our conscious repertoire at our human level that which previously was left out.
