Ego often gets a bum rap
I was happy to see the video of Dr. Jill Bolte-Taylor, author of "My Stroke of Insight", a while back as she exemplifies why we need an ego and why is not a good idea to try to "get rid" of it.
First of all, unless you want to damage the left hemisphere of your brain (which was her challenge when she had the stroke), you are going to have a sense of "identity" which is what the ego is. It is the mental construct of the "false self".
Ego is imbedded within your personality. Within the word personality is "persona", which means, "mask". It is not the real you, it is what I call the "Mental Me"; the story of who you THINK you are. This is in opposition to the "Magnificent Me" that most people apparently are not aware of.
