Non-Judgement.

Being whole and healthy requires consideration of phenomena, before judgement is made.
A judgement, made before consideration of phenomena, finishes the phenomena.
To judge a thing, renders that thing finished-with, and extinct.
Unjudged, that thing remains a phenomenon, vital and active.
Judging takes a thing, labels it, puts it in a box, and assumes it as understood.
Unjudged, that thing remains an active source of information and potential.

The thing may lead to other things.
Other things may, themselves, lead to still more...
It, and they, may be essential to the continued unfolding of things.

To judge, is to put an end to potential.
To not judge, is to consider potential, and allow an unfolding of events.

Taoism is: consideration before judgement.
Taoism is not: judgement before consideration.
