When *really* high - yeah, very heavy strobing of pretty much everything, although as I understand individual experiences may differ here, and possibly parallel the progress of insight.
I'm assuming that you're not a regular smoker, or that you smoke heroic doses of weed in a sitting as only extended periods of not smoking, or doing things like hammering a 1/4 oz of weed over a very short time period have
ever led to that the sort of results you mention. Even then, I don't recall it as being similar to the strobing common in Equanimity as there was nothing of the sense that the entire perceptual field was flickering in and out. Based on this, and obviously I'm only speaking from my own experience here, I cannot find anything other than a very, very tenuous parallel between this and the progress of insight.
But when only a little high, then just a very natural way of experiencing reality to which Tommy's points 1-4 definitely apply and happen automatically
It may be more accurate to say that being stoned has the potential to make it easier to experience reality in the way I aim toward in this exercise, in my experience it doesn't
cause reality to be experienced in that way. Either way, you're missing the point entirely. This is an exercise aimed at developing the affective mindstates conducive to practice, not a clarion call to stoners. That said, if you find smoking weed gets you where you want to be then do whatever works for you.
This is why people get high, not for the scary strobing.
Perhaps this is why
you get high, I can't say that it's entirely true for me.
