David Ingram has an interesting meditation technique that I am trying without much success. I'm interested in whether anyone else has mastered it and whether any other teacher teaches this method. Ingram says we can be mindful of impermanence not only when an in breath, for example, arises and passses away but also many times during one in breath. Here is a quote from his book.
"I mean that sensations arise out of nothing, do their thing, and
vanish utterly. Gone. Utterly gone. Then the next sensation arises, does
its thing, and disappears completely. “That's the stuff of modern
physics,” one might say. “What does that have to do with practice?”
It has everything to do with practice! We can experience this,
because the first set of vibrations we have access to isn't actually that fast.
Vibrations. That's right, vibrations. That's what this first characteristic
means: that reality vibrates, pulses, appears as discrete particles, is like
TV snow, the frames of a movie, a shower of vanishing flower petals, or
however you want to say it. Some people can get all into complex wave
or particle models here, but don't. Just look into your actual experience,
especially something nice and physical like the motion and sensations of
the breath in the abdomen, the sensations of the tips of the fingers, the
lips, the bridge of the nose, or whatever. Instant by instant try to know
when the actual physical sensations are there and when they aren't. It
turns out they aren't there a good bit of the time, and even when they
are there, they are changing constantly.
We are typically quite sloppy about what are physical sensations and
what are mental sensations (memories, mental images, and mental
impressions of other sensations). These two kinds of sensations actually
oscillate back and forth, a back and forth interplay, one arising and
passing and then the other arising and passing, in a somewhat quick but
quite penetrable fashion. Being clear about exactly when the physical
sensations are there will begin to clarify their slippery counterpart that
helps create the illusion of continuity or solidity: flickering mental
[snip]How fast are things vibrating? How many sensations arise and
vanish each second? This is exactly what you are trying to experience,
but some very general guidelines can provide faith that it can be done
and perhaps point the way as well. Begin by assuming that we are talking
about one to ten times per second in the beginning. This is not actually
that fast. Try tapping five to ten times per second on a table or
something. It might take two hands, but it's manageable, isn't it?"
