Who is the observer and what is observed?

He asks:
Can the world exist outside the mind?

Can there really be objectivity?

Me:
Can the knife cut itself?

Can the eye see itself?

This world is the outcome of our mind. Mind existing as division.

Is the observer different from the observed?

What happens if there is no observer and nothing observed?

So in order to answer both your questions, we need to look in-depth at
the very nature of mind:

Can mind exist outside division?…

Who´s the subject and who the object?

Are subjectivity and objectivity ever separable, or intrinsically one…?
