I've read about ego-dissolution as the effects of nearly overdosing on LSD... and I've also heard that it could be achieved through hours and hours of meditation. I have just been trying to research this more on the internet, but I found that there's barely anything about it... or at least under the name of "ego dissolution"... does it have another title?

Anyway, does anyone here know much about this subject? I'd love to learn more. When they say "countless hours" of meditation for it to occur, do they mean countless hours overall? or countless hours at ONE time. For example sitting there for 20 hours (+) meditating or something (completely random guess, I havne't the slightlest clue about how long it would take). Could this be considered "enlightenment", or that something completely different?

Also what happens during ego dissolution, I know you lose the feeling of self and you look at things objectively, but what happens afterwards. Has anything changed aside from a new experience? Or do you continue to look at the world through this shattered view. What happens to your memories as well? It couldn't suddenly just wipe all memories clear of your mind, so what does it do? How does it work scientifically, and how do old memories of self and this new broken self interact?

That's quite a few questions up there. Feel free to say whatever you know, or even link me to a place where I could read more about this. All my searches have resulted in how this is achieved through drugs - I'm curious more about the meditation one.

[Edit: I know that after ego dissolution, you apparently refabricate this new sense of self... Well my question is, what if you experience things in the wrong way, what if you get confused while you're all "broken", and look at things in a twisted manor. Is it possible to refabricate your self with false views, and pretty much end up insane?]
