point of the tweet is that you can't really give some things to other people, you can only point. As it happens, "not the body" and a bunch of minor related stuff.
Experiences and abilities are not valueless, but they are most valuable when they lead to realization/awakening.
that's a very nice thing. Doesn't really require the "no space" though. Even within "something" most something is almost nothing. No space knocks people out, I don't get that, so I'm pretty sure I don't have that ability. Would be nice, though.
Hmm...
Sounds sort of like when I slop into certain jhanas or prolonged insight states where everything feels very thin...
Never had that as a core realization, though.
