Here's a quote, about 40 minutes in...
"If we attach to calm then we tend to go into trance states, or we may find ourselves just loosing attention, becoming sleepy. If we attach to the ideas of impermanence we can find ourselves becoming distanced from experience, that is not really resonating with it, not really tuning into it, not really feeling it, being present with it. We can develop certain dismissive attitudes or dismissive stance towards the experiences that happen. "Oh that's just changing stuff, so what."
And so instead of there being a properly established Ground of Being that's bright, luminous, immaculate, suffusive we develop views, ideas, opinions, standpoints that are not shining, luminous, immaculate, suffusive but that tend to become aspects of "My Self." And this means there's a certain fragmentation that occurs, my self as an experience in the way I'm using it is something that splits away from experience and thereby thinks it has the experience. "Here I am having this, I can get this, I can do this, I can make this happen" and so forth.
We descend from what was an essential integrity and essential wholeness back into behavioral dualism. And then of course the whole thing begins to break down because for a certain amount of time we are able to "do" the calm, "do" the metta, "get" the anicca going but its becoming much more dishonest in a way. It becomes a strategy rather then a realization. One is no longer meeting the experience fully and embracing it fully."
