Hello Mike,mikenz66 wrote: Having said that, I wonder if those numbers are just hyperboble, to make a point about meditative experiences. The primary purpose of these texts (Sutta, Abhidhamma, Commentary..) is, in my view, an aid to making sense of experience. Even without any meditative experience at all, it's not hard to see that sense impressions appear at the six sense doors with extreme rapidity. You don't need some ancient text to figure that out... With some development of mindfulness and calm, the rising and passing of the sense impressions can be seen with increased rapidity.
Yes, it's not hard to see such extreme rapidity -- but only when such rapidity is directly experienced. But we may not have such experience all the time; usually we may encounter sensations which we perceive to be lasting for some time. When there is no such experience of rapidity, the rapidity is simply not there; I mean it is not even in the background.
The idea that Cittas are arising and passing away with extreme rapidity even when not experienced as such, does not make sense to me. I would appreciate if you or someone else could correct if my understanding seems to be wrong.
