What do you think it means Mary?
I don't know what it means. You use different terms. Is it "listening and wanting to understand where the other was coming from"? Is it "[d]ying to self"? Is it "an inquiry and dialogue into the nature and behaviour of ego"? Are any, or all, or some of those, "breaking the will of the ego"? You're the one using the term, can't you say what you mean by it?
