Whether you like it or not; you can not avoid evaluating while you observe.

Beware the myth of objectivity!

There is a neat way out of this dilemma:

Infinite honesty and non-repression of data so as to SEE ALL OF YOU, THE OBSERVER; allows you to "see things as they really are" because you are then not getting concealed aspects of the observer unknowingly mixing with the observed.

What I'm saying is, UNLESS YOU SEE ALL OF YOU, then concealed bias may cloud your judgement. To properly evaluate reality objectively you must "see it as God sees it", so must swim in Him and experience ALL YOU so none-of-you is invisibly muddling the picture. If part of you is no longer blocking the view; you are free to see things as they really are. Know all the observer, then you observe accurately.
