A fact.

Your brain works in a natural way that you can't change. you can only become more like yourself (peace , integration) or more dislike yourself (stress) -- and the other types of people you interact with either separate you from yourself, or they mend you together. Basically.

You can totally remove your ego and become one with humankind, but doing so will take types of people that essentially have a very similar ego as you to do so. (like other identicals) That's what people mean when they say ego is both the problem and the solution.
