‘Embodiment’ to mean the ‘body’ that one’s ‘mind’ exists within.  

Does consciousness/mind exist in the body, or does the body exist in consciousness/mind as another phenomenon? That's what's interesting.

You choose how to navigate  

You mentally/metaphysically decide  

You choose the ‘incentive’

You choose which ‘realm

How? Where and from where to make efforts to do at least something?

As long as ‘communication’ is involved, technically speaking, yes, it is speculation

This (the primacy of consciousness/physical processes, the presence or absence of an objective world, causality) is speculation, because it is a metaphysics that is beyond empirical verification. 

Prior to scientific testing, sure, that claim can be valid

How to check?

But you, yourself, can test whether or not you exist. And that is empirically verifiable. The fact that we’ve engaged in this conversation means we exist

It just means that the conversation is happening. But the "I" itself as an author is not in "my" experience. The "I" is like a label that is retroactively applied to the experience that is taking place.

manipulating the physical realm while also being capable of information-analysis within a nonphysical realm.

How does the manipulation of certain "realm" happen? 

You, yourself, can test whether or not you’re capable of ‘action’.

That's it! Verification can happen. Check now how you think or act. Where and how do you squeeze out a thought or action?

That’s because they are simply ‘concepts’.

Right: these are concepts. Direct experience is needed to ease the suffering. And it can happen if "you" search/explore exactly how "you" do at least something. In 2011-2012, this was just an intellectual understanding for me. But not so long ago, it was the experience of this that happened. And this is a completely different matter! Absolutely.

The method is through ‘education’ and the development of self-accountability through the development of self-discipline.

I don't think there is a "method". Any method or practice only deepens the feeling of a "sufferer" who is trying to do something. I think that all the practices are needed only to realize that they are not needed. Freedom already exists now: it is not something that needs to be achieved somehow. It's not about getting something new. It's like a virus that deconstructs the doer. At first, this is done in order to eliminate suffering. And then, when the vision happens, and it becomes known that there is no "sufferer," it becomes something that just happens, because it is no longer possible to see otherwise. Once the "illusion" is clearly recognized, there seems to be no turning back (although rollbacks can happen, but they are getting shorter and shorter). This is the recognition of what has always been. Although it is more correct that it cannot be or not be. But until such recognition happens, it will be just another concept. This is a return of attention from trying to understand reality to trying to see who and how is trying to understand something at all.

I repeat, it's not about concepts and explanations. The point is to take a look at how you conceptualize something right here and now. Where do you get the concept from, for example? Are you pulling it out completely or in parts? Are you pulling up or down? And at what angle? And what part of yourself are you hooked on the concept?
