There is a song - it is one of those profound ones that explores , I guess, existential concepts :
I really do not know
how many - selves reside in my mind
One self paints and the other one slathers paint on herself
yet a third one decimates the painting - are they all one ?
When I am drunk with life and the reins slip
there is that one who grabs and holds and does not let go
- are they all one?
These numerous , multiple selves
are they really one ?
