Good morning
Good observations but here are some comments.
After reading this question I did it again. It doesn't seem that thought controls it but there does seem to be a sense of intention.
In direct experience the sensation of the hand moving is experienced. The sense of intention/urge to take the action is felt however it's not clear that it is causal.
What is meant by "a sense of attention"? Is it a sensation : if it so where is it located? Does a sensation control the movement?
Is it only a thought? LOOK
There are sensations in the neck when I look for a separate individual however they are not always there as the palm flips up/down.
Do you find a separate individual in the sensations?
Here is an exercise for you, I wish it will help.
Find a comfortable place to sit or lie.
Take in a few deep breaths to settle the dust and then relax for a bit.
Spend only 30 to 60 seconds on each component of this exercise.
Bring your awareness to your entire body - sense it fully, head to toe.
Run your hands down over your torso. Feel the solidity of it.
Now bring your awareness to your feet. Again, feel them. Move them a bit.
Then bring your awareness to your hands. Open and close them.
Bring your awareness to your face - all of it. Touch it with your hand.
Now point your index finger to where "insert name" is located.
Touch the exact location of "insert name".
Answer these questions:
Were you able to find and feel "insert name" in a direct way like the other parts of your body?
Where is it?
What did you find? Something? Anything? Nothing?
What sensations did you feel in your body that identified "insert name” (If any).
Tell me what you experienced and found, by way of direct experience.
Best for you
