Take your time with the mirror exercise, it is a beautiful pointer and has so many layers.
The first layer somehow makes clear that there are so many layers beyond!
(2) Is there any connection between the felt sensations and the image in the mirror?
There's no actual connection. There's a sensation labeled "shoulder" and there's also an image in the mirror that's labeled "shoulder." There's also a mental image that this investigation is emanating from a "looking" place behind the eyes, and that the "shoulder" sensation is located in a specific place slightly below and to the right of that. The only connections are thoughts: the learned perception that these share the same name because they refer to the same "part of my body," and the conceptual correlation that when "I move my shoulder" then the sensations match the visual movement seen in the mirror. (Thoughts tried arguing about this, claiming it was in DE. I pointed out that correlation does not imply causation. If someone expertly mimics me, the images of their movement would correlate with sensations in "my body," but that wouldn't be proof of a connection.)
(3) Is there any connection between the felt sensations (labelled ‘hand’) and image of movement in the mirror?
No, there are only thoughts -- a learned correlation. I tried this again with my computer screen and web cam instead of a mirror, making it even clearer that the connection is only conceptual. Just like the image in a warped mirror isn't proof that "my body" has changed shapes, and the image in a novelty filter on Zoom or FaceTime isn't proof that I've turned into a cartoon animal.
(4) Is there any connection between the felt sensations (labelled ‘hand’) and the image ‘of movement’?
It took some time to see that the same "correlation does not imply causation" must apply here. If I got a shot of novocaine and felt no sensations in my wiggling fingers, should I use that to determine whether this is "my hand" or not? Of course not. Sensation happens or doesn't, and images are seen or not, but these can and do appear independently.
(5) Now, pay attention only to the image in the mirror. Does the image by itself suggest in any way that is ‘you’ or ‘your body’? Does the image itself suggest in any way that it is a ‘body’ at all? Or are there only colours and shapes?
No, the images are just images. In direct experience, there are elements like images, sensations, and thoughts, that appear to show up simultaneously. Thought then bundles and merges these together into one perception of "body." This is further merged with the appearance of memories, preferences, and other thoughts, resulting in one perceived "me."
(6) Just by the image in the mirror, is there any ‘knowledge’ that there must be legs, or only thoughts and mental images suggest so?
To find the other body parts not seen in the mirror requires imagination. There's a mental image that's so familiar as to not seem like imagination at all. It's been imagined so consistently as to seem real. (It's seen that this phenomenon underlies our entire conversation and investigation.)
(7) Now turn away from the mirror and look forward (don’t look directly to any body parts). Is there a ‘body’ anywhere when all thoughts and images are ignored, or are there only sensations?
There are only sensations. Imagination is required to call up the mental image of a body and correlate the sensations with specific parts of that picture.
(8) Start to walk slowly. Is there a ‘body walking’, or are there only sensations? Is there actual experience of ‘walking’ at all?
In DE, there are sensations and there are thoughts. "Body" and "walking" are only content of those thoughts, so "body walking" is not in DE.
(9) Are the sensations localized in space, like ‘going through the room’...?
Applying the same "correlation does not imply causation" standard, it's seen that there are sensations in DE, and there are images in DE. Anything about "body" "moving" or "room" are labels and interpretations, not in DE. I'm going to practice with this more today on a walk because it's clear that this is only the subtle beginning of this seeing and still feels tenuous, like it would be forgotten if not reinforced or deepened soon.
Thanks again!
