Really? Can you show me where? Did they give an explanation for the deletion? Did you ask about it?
I clicked on one of the links within your link, Sutta SN 22.1. It ends with
"He does not assume consciousness to be the self, or the self as possessing consciousness, or consciousness as in the self, or the self as in consciousness. He is not seized with the idea that ‘I am consciousness’ or ‘Consciousness is mine.’ As he is not seized with these ideas, his consciousness changes & alters, but he does not fall into sorrow, lamentation, pain, distress, or despair over its change & alteration.
“This, householder, is how one is afflicted in body but unafflicted in mind.”
In other words, there isn’t some way you can conceptualize self that will reduce your anxiety about what the self is.
“living a fantasy” assumes that there is some reality to live in. A fantasy compared to what? Fantasy is “the power or process of creating especially unrealistic or improbable mental images in response to psychological need”. But for most of human existence, we haven’t known what “especially unrealistic” is, so we created religion and myths and “I think therefore I am” to deal with the improbable reality that we are here. We’re still grappling with those questions because we still don’t have all the answers.
That’s the bad news, we don’t know what we are. We have only recently determined the age of the universe, and that we evolved from earlier, simpler forms. The implications of that are enormous and wipe away almost all of the speculation that came before that. This is upsetting, unsettling, and the cause of a lot of anguish by a lot of people. Many are hanging on to the old mechanisms, I consider those to be fantasies.
The psychological need to have answers doesn’t go away when a religious person realizes they are living a fantasy. But, that’s different than seeing all of reality. Losing religion is a process of understanding the probability that religion is wrong. You don’t then realize a 100% probability of what is right. Same for understanding “self”. The latest neurology, or an insight from an expert in Buddhism, does not give you “the” answer. You seem to want “not living a fantasy” to be “the answer” so it’s unsettling that there are all these people saying they have an answer, and you can “poke holes in them” but you don’t have the answer either. What you miss is, some of them, actually quite a lot of them, are saying “I don’t have all the answers, but here’s what I know, here are some ideas about how to live in this world of unknowns, and in a time of rapid change.”
