you need some ego. otherwise you won't know where to point your fork to eat.

you reminded me of some John lenon comment on ego death :

   I got the message that I should destroy my ego and I did, you know. I was reading that stupid book of Leary’s; we were going through a whole game that everybody went through, and I destroyed myself. I was slowly putting myself together round about Maharishi time. Bit by bit over a two-year period, I had destroyed me ego.

   I didn’t believe I could do anything and let people make me, and let them all just do what they wanted. I just was nothing. I was shit. Then Derek tripped me out at his house after he got back from L.A. He sort of said “You’re all right,” and pointed out which songs I had written. “You wrote this,” and “You said this” and “You are intelligent, don’t be frightened.”

I haven't quite achieved an ego death yet through meditation, but reading through a fair amount of psychedelic journeys suggests that eliminating the ego, while perhaps useful and enlightening in moderation, sort of defeats the point of living a life in this world. If the world really does exist simply to provide experiential distraction from the existential dread of being an absolute consciousness in the void (which is a big if), why be in such a rush to get back into that base state? Go experience all the wonders of the world, take risks, spread positivity.

No-self is not really about eliminating the ego, it's about eliminating the craving for an ego. These two are not the same; in fact, the latter seems to be harder. It's why so many meditators anecdotally get stuck in their "Dark Night". I don't know what psychedelic "ego death" does exactly, but I'm skeptical that it addresses craving.

There might be some overlap as psilocybin can be used to treat addiction. There’s a recent John Oliver episode on it
