Here is a very simple way of thinking about this process:
Recognize vs. realize
It’s possible to recognize what’s here, to notice it, to have a glimpse. And it’s possible to realize it, to live it, to deepen in lived familiarity with it.
Nature of reality vs. nature of illusion
What can be recognized and realized is the nature of reality, what we – this field of experience – really are, aka (a) presence, love, awareness, (b) all of this as this field of appearances, and (c) capacity for all of it.
And we can recognize and realize the nature of illusion, how the world of apparent separation etc. is created through taking images and thoughts as true, and all the dynamics around this.
As a whole vs. parts
The nature of reality and the nature of illusion can be recognized and realized globally, as the whole of this field of experience.
And it can be recognized/realized by the different parts of me, the subpersonalities, the different aspects of this psyche. This happens through holding satsang with these parts, as they surface to find their own liberation, to realize the nature of reality and illusion for themselves, to recognize and realize what they really are.
Milestones vs. ongoing
There are some common milestones in recognizing/realizing the nature of reality and illusion, and it’s also ongoing. There is always further to go. Reality keeps opening up to itself. There is (most likely) no end point.
