Hi Mark,
Well, the body is the object in which sensations are felt. This can be confirmed simply by causing the sensations by touch. This is the only thing whose sensations can be felt by awareness.
Im not totally clear on your answer, but I will say this.
Without thinking about it, how do you know the body is an object?
Don’t objects, by definition have shapes, sizes and boundaries?
Lets see if this makes it clearer:
Deeper Body Investigation
Here is an even deeper investigation of the body. Please follow each step, don't leave out any. Take your time. Don't move to the next step until the previous one is clearly seen. Repeat the exercise several times.
Stand in front of a bigger mirror.
(1) First, close the eyes and feel the sensations labelled ‘body’.
(2) Then open the eyes and look into the mirror while still paying attention to the sensations. Is there any connection between the felt sensations and the image in the mirror? Or just thoughts (and/or mental images) suggest that there is?
(3) While still paying attention to the sensations move one hand and observe the movement from the mirror. Is there any connection between the felt sensations (labelled ‘hand’) and image of movement in the mirror?
(4) Now do the same movement with the hand, but this time look at the hand directly, not from the mirror. Is there any connection between the felt sensations (labelled ‘hand’) and the image ‘of movement’? Or only thoughts suggest it?
(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?
(6) Where the mirror ends, some parts of the body (probably legs) cannot be seen. Just by the image in the mirror, is there any ‘knowledge’ that there must be legs, or only thoughts and mental images suggest so?
(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?
(8) Start to walk slowly.
Is there a ‘body walking’, or are there only sensations?
Is there actual experience of ‘walking’ at all?
Or just THOUGHTS ABOUT ‘walking’?
Can such a thing as ‘body’ be found OR just THOUGHTS ABOUT a ‘body’?
Can such a thing as ‘walking’ be found?
(9) Are the sensations localized in space, like ‘going through the room’; OR is there only an image that is labelled ‘room’ and appearing sensations without any location?
