Well, I am sure there are many different interpretations and ideas of what complete ego loss is on an acid trip, but Ill give you my view of what I believe it is. Basically, it's happened to me only once, I've yet to take any daring doses. Four hits of very good geltabs, and around peak time, I suddenly had complete loss of who I am in this world, what my name was, where I was, or why I was here. I just felt like an energy, I knew that I was something, and that I had a memory of past events, however no matter how hard i tried, I couldnt recollect anything. This didn't last too long for me though, I came back, and honestly it was not a very pleasant experience for me. Maybe I wasn't ready for it, many descibe it as a beautiful experience, where you are just one with the universe etc..but that was not my case, it scared me.
it is when your ego is stripped away. basically you are completely selfless. you are not worried about you, only the world around you, you become one with your surroundings and everything is unified into one. you will lose your wants and just appreciative of what is around you.
I'm just learning about this myself. Here's a wordy explanation from the "Tibetan Book of the Dead" http://www.lycaeum.org/books/books/psychedelic_experience/tib21.html The predominant physical symptom I had was my body flowing like wax.
ego death is..lol.. Well you might think your all big and bad and talk alot of shit, and you got big balls, and carry chips on your shoulders... Then one day you take a hit of acid. And you go into the woods and you park your ass on a tree.. Tree gets mad your sitting on him and asks you politely to move. And you say fuck you tree. Tree says Ive got freinds and my feinds are all around you.. He calls his freinds over... A Squirrel.. Who calls you a nut! and you get into a big fight with a squirrel... Then comes along a wood pecker and and he starts laughing "ha ha ha ha" And a beaver comes and smacks you in the face with his tail... in the end the cricket tells you a new weather forecast... and you see how small and fragile you are...
