Look without looking?

"You need to learn to not think about yourself so much. Like look in the mirror without looking at yourself. You gotta look past yourself."   ─Ma

Ma said this to me just now. I don't really understand it though. She told me that I don't know how to do it because I don't understand what she's saying. But I really don't.  How can you not think about yourself when you have to be yourself everyday?  How can you look at yourself without looking at yourself? I just don't get it.
