So...you want to know yourself?
Listen then to everything else but what you think is you,
Even to the silent interactions;
You are but the summation of your external influence,
your internal world is the reflection of the outer.
Or is it the obverse of that?
But if you want to know the real non-you:
There exists this black hole at the centre of your universe
Get ****** into it and know that you never really existed, externally.
