An important point that perhaps needs expanding upon. I dislike the word "Ego" as it comes with Freudian trappings, but I suppose "Self" is similar.

I think that some people may well be put off deepening their self-awareness if the ultimate state is seen as some selflessness - the disappearance of who we are. The experience of selflessness is very real, but at some point our inner voice returns. However, our point of view has changed, and maintaining that new perspective requires practice so that our inner voice no longer has the power to attract us to delusional thoughts.
