Neither do I, Phil. I would be quite intrigued with what you disagree with.
If I may (though not speaking for Phil, of course), this is my uninformed, amateur-mystic thoughts. ("Amateurmystic"—I like that word!)
1. All mystics agree that Ultimate Reality—whether It is called Allah, Brahman, Buddha-nature, En-sof, God, or the Tao—cannot be grasped by thought or expressed in words...
I wouldn't express this concept that way, as it would
make grasping that Ultimate Reality beyond everyone's reach, which I don't believe it is—but then, I suppose it depends on your image of what is "grasped." While it is so that "the Tao that can be spoken is not the eternal Tao," that in itself is an indirect means of expressing, and hence grasping, the eternal Tao (famously brilliantly so, in my opinion). Rather, I would word it "—is only indirectly grasped in thought and expressed in words."
2. The reason Ultimate Reality cannot be grasped by thought or communicated in words is that thoughts and words, by definition, create distinctions and, hence, duality. Even the simple act of naming something creates duality because it distinguishes the thing that is named from all other things that are left unnamed. However, the mystics of all the great traditions agree that all distinctions are imaginary and that the Ultimate Nature of Reality is non-dual.
The implication of these words is that the Ultimate Reality, by virtue of "the word," is both something beyond reach and existing eternally unreachable, which creates that image of the Ultimate Reality that upholds duality by keeping us separate from the Ultimate Reality. This is a valid image that points at unity and that is supported by many, but this wording presents
only this dualistic image and not the other, the united, image. I'm of the mind that
that monistic image, essential to the mystic, is not "grasped" (to borrow the context they use) in dualism—or, ultimately, expressed here in #2 (pun intended).
Though perhaps that is with a certain intent, and it will all be covered later.
3. Although mystics cannot define Ultimate Reality in words, they still use words to point to That which is beyond words. For instance, all mystics agree that, while Ultimate Reality constitutes the true nature of everything, in itself It is nothing.
True; but still housed in the dualistic image. That is, of course, not A Bad Thing, but ignoring more monistic images seems more a means of holding the uninitiated as separate from the mystic as this image of the mystic is from its Ultimate Reality.
4. Although mystics say Ultimate Reality is not a thing, they also agree that this emptiness or no-thingness is not a mere vacuum. It is radiant with the Light of Pure Spirit, Primordial Awareness, Buddha Mind, or Consciousness Itself.
Perhaps not a helpful image (I can only take it metaphorically). It doesn't succeed in an essential shift in perspective that
conveying this idea would entail.
5. Mystics of all traditions also agree that when distinctions created by imagination are taken to be real—especially the distinction between 'subject' and 'object', 'I' and 'other', 'self' and 'world'—we lose sight of the Ultimate Nature of Reality and fall into delusion. This is the cause of all our suffering.
I get what they're trying to say, but again take issue with the wording. First, it says that we can see an Ultimate Nature of Reality that stands
in constrast to the distinctions we create with our words, which are unreal. Putting aside for the moment that while the Ultimate Nature of Reality is wordless and its image "most certainly" is not, if the distinctions are not real, they could leave no impression on us (this is where Dogen's images are more pleasing)—at least, that is implied in how I define "real". Yet, the impression and its consequence is upheld in these words. Rather, I would say that we indulge the distinctions, which are a product of imagination, and lose (invest) ourselves in the story of our own words (from #2 above). What can—I say I like the movies (i.e. "life is good").
What "we" "invest" is belief.
6. The fact that distinctions are not ultimately real means that we are not truly separate selves. In Reality, all mystics declare, our True Nature is God, Brahman, Buddha-Nature, the Tao, or Consciousness Itself.
Again, I take issue with this: if "no separation" is real, a distinction is made.
Okay, I'm tired of finding fault.
