No idea what it means, but i'll share my own similar experience!
I just did my first Sakya lineage Chenrezig practice the other day, it had a variety of lines about the potentiality of mind and thought if I recall.
Not sure what it is supposed to mean, but interestingly I have found that so far the Vajrayana stuff really resonates with me, in some ways the deity yoga practices for me have brought about a more effective contemplative state for things like emptiness/egolessness, and potentiality of stilled mind/whatever you want to call it than I would get with a similar period of just insight meditation etc.
I know for me, there is always a mind that simply does not stop, full of all kinds of "good" and "bad" things. I picture it like a wheel of faces, words, whatever else..it's always changing but the motion of it is pretty much the same. You could argue that while it is never the same wheel form second to second, it always rolls the same way. Personally, I can be as mindful of this as I want, but it is always there, the difference is whether or not I am living in that mind or not...if that makes sense. It is in constant motion though, it never disappears for me. and then theres a mind that is quieter, but harder to see, that feels like pure potential, if I can reside in that one, I can kind of ignore the other one if I choose.
I realize sadhanas are not supposed to be replacement for the foundational stuff, but man at least for me they do the same stuff, but fast!
Anyway, whether it's distracting thoughts or intentional ones, they are all without a self.
Since you've mentioned you have issues with being distracted, i'm interested to know how the experience was for you in general, though I realize I've rambled on pointlessly without giving you any answer to your question lol, sorry!
wo, if distractions and all manifestations of mind are this same intrinsic awareness, why do some appear desirable (calm) and others undesirable (agitation)? Is that just another effect of ignorance? It's stunning to me that something seemingly empty and unblemished can manifest in such varied ways, even painful ones.
Yes.. Clinging, I think. What I try to do is take two emotions, say joy and anger, and follow them as they arise throughout my day, watch them appear and disappear, then try view the "thing" that is perceiving them and trying to create 'views' on them. With anger, I have lots of opportunities for this because I have two kids! Anyway, when I do this I can indeed see that whether joy or anger they function the same way, the times when they continue to exist, and become something else is when my "ego mask" (sorry I don't have a standard vocab for this stuff) propels them on by clinging to them, and forming opinions on them. Their nature seems to be the same.
What a bunch of nonsense I just wrote, oh well...heh.
