At a micro-phenomenological level: neither pushing nor pulling on sensations.

We 'pull' on sensations when we want them to persist. We might call this 'grasping', the sensation will slip away into impermanence no matter what, we get to choose whether it painfully rips out of our 'hands' or we smoothly let it go.

We 'push' on sensations when we want them to go away. We might call this 'aversion', the sensation will slip away into impermanence no matter what, we get to choose whether we strain to shove it.
