@jansen Are you saying that if you see the breath inhale (arise) and exhale (pass away), or the belly rise and fall, or your footsteps rise and fall, that this is knowledge of arising and passing?
In a preview of your introduction to meditation video, I do remember you talking about momentary awareness and the rapidity of the mind that changes and “refreshes”. It compared that to the ability for use to perceive motion; the difference between a photo and video. I thought that was the best part of the video and I was impressed that you would mention that in an introduction to meditation. I also mention things like that in my abhidhamma book.
In the same way, the higher the refresh rate, the more realistic and smooth things “appear”. While the mind door is mentioned in the abhdhamma to occur hundreds or billions more times compared to the eye door, the refresh rate is still quite fast.
