The end purpose of meditation is to make moving and being still roughly equal in affective valence, in feeling tone. If you can’t sit still, you are being driven around.
Many meditation teachers preach to “still your thoughts”, but the thoughts themselves come from an emotional impulse to move, rather than simply be. It is always the emotions at the root, or, rather, the sensations. As I have said, I think the order is sensation, image, feeling, thought. The thoughts are just a guidewire you can use to travel deeper down. There is, I think, a thought within a thought. There is a way of being aware of them, but separate from them.
I’m going to go work on that. Peace, which is what we all hunger for, is found in this direction, I am quite sure.
