Some levels of Oneness...
All as Spirit
Ultimately, it is all Spirit. The field of seeing and seeing is Spirit, absent of any I. The Ground of seeing and seen is Spirit, absent of any I.
And we can have a glimpse of this, maybe interpreted as an experience of oneness between I (as this human self) and Other (as nature, God, Spirit).
We can have an intuition or a sense of it, again typically interpreted as a sense of Oneness of I and Other.
There can be an immediate and more stable experience of this Oneness, that it is all Spirit.
Also here, there can be a sense of I and Other overlaid on the sense of Oneness. The volume of both can be turned up or down, one going into the foreground and the other in the background, shifting back and forth.
Finally, there is a realization that the field of seeing and seen is inherently absent of an I. There is no I anywhere, just a field of Spirit as Ground, seeing and seen. The sense of center falls away. The sense of subject and object falls away. Spirit as the field of seeing and seen, as a whole, is its own subject and object.
It is not touched by oneness and multitude, yet arises and can be seen as either and both.
And it is still functionally connected with a particular human self, which now arises as anything else. It is just part of the field, living its own life, just like clouds moving across the sky, cars passing on the street, other people living their own life, the world living its own life. It is Spirit as form, unfolding on its own, absent of any I anywhere.
Human level: deepening into knowing myself as an individual
Since Spirit, in our case, is functionally connected with a particular human self, and lives through and as this human self before and after awakening to itself, the forms oneness takes in our human life is also interesting.
At the ultimate level, all is Spirit independent of its particulars as form.
And at our human level, everything I see in the world is also here in me. This is a deepening of knowing myself as a human being.
Every quality and characteristic I see out there, in the world - in the universe, in the Earth, ecosystems, animals, plants, humans, cities, stories, mythologies, movies, fantasies, dreams, they are all also in here, in my own human life.
It is a deepening of knowing myself as a human being, and also a deepening of the realization of all as one. In my human life, all I see in the wider world is also right here, closer than my own breath.
At the most disowned, Spirit can recognize all arising as Spirit, but still see some qualities arising in other human selves and not in this one. This makes for a less complete, less human and more frozen way for this human self to function in the world. It makes for a less healthy and mature vehicle for Spirit in the world, even as Spirit has awakened to itself.
A little less disowned, Spirit can recognize all arising as Spirit, recognize in this human self what is sees in the wider world, but not be much familiar with it in this human self. It is acknowledged, but there is not much familiarity with it. Again, it limits how this human self can show up in the world, it limits its repertoire and what is familiar to it.
As these aspects become more owned, as they move from "it" to "me" and "mine", there is greater and greater familiarity with it, not only out there, but also in how it shows up in this life.
It becomes known in a far richer way, and with a different (more conventional) sense of intimacy. It becomes part of the daily repertoire of the human self, available when needed.
There is a sense of deepening humanity, a more intimate connection with others, and more juiciness in life in general.
It is even a part of developing skillful means, since this human life is the tool of Spirit in the world, even after it awakens to itself.
Human level: deepening into knowing ourselves as us
Spirit also shows up as Us, as the multitude of beings and all of our many relationships, and this is another deepening into oneness.
When Spirit awakens to itself, what does that mean for all of the relationships of this human self to other people, to animals, plants, ecosystems, the Earth as a whole, past and future generations?
What does it mean to relate to those where Spirit has not (yet) awakened to itself? What does it mean for groups where Spirit has awakened to itself, to varying degrees, in many of us?
Again, as with the deepening into seeing everything in the wider world also in my human self, this is an infinite exploration process. As long as there is the world of form, and a vehicle in this world of form, it has no end. It continues to richen, deepen, mature, develop, evolve and change.
In all of these ways, there is a deepening intimacy.
At the Spirit level, it is beyond intimacy since it is all Spirit. It is the most intimate.
At the individual human level, there is the deepening intimacy of finding and knowing in myself, in greater and greater richness and depth, any and all of the qualities I see in the wider world.
At our collective human level, there is the exploration of the infinite ways Spirit shows up as Us, in all of our many and varied relationships.
