Becoming or Being?

"The nature of becoming is a constant filming over of where we begin, while the nature of being is a constant erosion of what is not essential." Mark Nepo

I wonder if that is true.  Is it true for your life that you have continually covered over who you were, only to again uncover it?  Perhaps it is true.  I have thought of it in terms of going back to collect something I left behind -- like my sense of wonder and play that I re-found on the beach where my parents would have taken me when I was a very young child.  Perhaps it is just a matter of semantics.  Our life process is continuing to uncover who we are.
