The part where you quoted me… I meant that once you lose the ego completely, there is no turning back. Before that, experiences of enlightenment, always lead to “falling down” from them. Yes, accepting the falls is necesarry if that’s what you meant. But at some point, there is no one to accept anything.
I’m sorry because I’m more familiar with Hindu terminology, so I’ll use it instead if you don’t mind. Lower types of samadhi (kensho?) attained by someone for the first time just can’t be forever. They have to fall from it eventually. Even the higher types of samadhi aren’t forever when one experiences them for the first time. Some are in extremely blissful states, yet still struggle to attain even higher states or they don’t want to because they want to help. But once one becomes a jivanmukta and “there is only Brahman” there really is no way to know or experience anything as you might imagine.
The point of Buddhism is not to ignore or fight inevitable change, since that causes suffering. The point is to accept it and go with the flow.
If I may tease a bit, I thought that change/stillness, acceptance/non-acceptance is also a duality that eventually disappears, and after Nirvana you pretty much become the flame of negation personified, so there is no teaching possible.
A person asked an avadhut, “What is your teaching sir?” The avadhut replied, “No teaching, no teacher, no taught.” And he disappeared.
Sorry if I’m confusing anything here, as I said, I feel more confident discussing those using Hindu terminology.
Nirvana has to be able to change from nirvana-without-rossum to nirvana-with-rossum, otherwise it is useless.

I am terribly sorry, if you want to experience God as yourself, I think seeking enlightenment is not the right path. Those who are there
genuinely (as opposed to a thought-generated state) say things like:
“If you knew what it is, you wouldn’t want it. How can you want it?”
“I don’t know what it is.”
“I’m aware of the pain but it’s not happening to me”
“I have no idea of telling myself how I feel”
“The experiencer must go also”.
Those are from my two favorites, who seemed to be way above the rest in terms of no-ego, actually the only favorites because the rest is in some ways always corrupt and I’m disgusted that people worship many of those. I will never follow their footsteps (any longer). From all I know, they all can be antichrists!
Anyways… it’s completely oustide every single desire and conception you might have. Even the experiencer is not there. It’s not an experience. That’s why I say it baffles me that people buy into that. To me, most just get stuck in some realities, which aren’t the ultimate ones (that are “desired”). You really have to be desperate to get there, rejecting everything until there is no one left to reject anything. How can you be certain you are at the ultimate point? You have to go on this path, sooner or later, as long as you perceive, there is this problem that the perception may be false. I think this might be the meaning of illusion - perception. It has to go. The state you supposedly desire has to be beyond perception, therefore…
