Albert Einstein is purported to have stated, "The universe IS an illusion, albeit a very persistent one."
I say, "What you call "your self, "me" or "I" is ALSO an illusion, albeit a very persistent one."
This appearance is all done with mirrors. It's a magic show! Nonduality can take the seeker behind the curtains and strip away the masks and makeup, revealing What IS, Simply Being... i.e. Naked Awareness, unfettered and untouched by its own shadow-play.
As 'Sailor' Bob Adamson pointed out, "This is not a reflection IN the mirror, it's a reflection OF the Mirror". As Muktananda said, "All of this is reflections of the Self".
That is All.
