I notice I am curious about this, partly because it’s not very clear to me yet.
Sometimes, shifts in perception is supported by a state. There may be a state that makes it easier to notice (what a thought may say is) all as one, all absent of any “self”, all as Spirit, all as love, meeting all as love etc.
So there is a shift in state, which invites a shift in perception, which in turn invites a shift in insight, and a shift in noticing.
When the state shifts again, perhaps into something (apparently) very ordinary again, the invitation is to keep noticing and questioning. Is it true it – the noticing, all as Spirit/love etc. – went away? Is it true this is not one, Spirit, love?
This noticing throughout changing states and experiences is in itself (sort of) a state, a state of noticing.
And it is also a shift from something that may appear extraordinary, an extraordinary state, to something very ordinary, noticing what’s already here in (and as) any state, any content of experience.
