Not all of us can be "best".Or, everyone of us can be -- and perhaps is -- but then "best" doesn't mean the same to everyone. It can even mean the opposite.Perhaps there is just no common scale.
Oh dear! You do violence to our word "best"!
Best is a comparative.
It is not possible that EVERY anything can be "best" or there is no comparative to indicate a superlative. Best indicates relative position when comparing.
And...if "best" can mean the opposite of itself....well....we may as well toss vocabular out the window.
I think what you are indicating by your statement is a reference to subjectivity.
But, I can't abide that, myself.
Our concepts stand or fall by the accuracy of their definitions.
The mystics want to blur the lines as much as possible by attacking definitions and rendering concepts vague. This allows them to use conceptual language any way they wish without leaving their audience a means of testing the reality of it all.
Take the word "spiritual" for instance. It can mean so many ill-defined things it finally means nothing much at all. It is like the word "cool".
If I put you in a room with many objects and tell you to find what is cool you might bring back an ice cube or an iPod.
Anyway...much ado about nothing here.
