Dao

Let's discuss some Primary-ish sources.

道德经 (The Way and Its Power)

There's multiple translations, and hover-over for individual characters - but since it's super ancient, there's a ton of interpretation involved. Still, it's interesting!

It could be worthwhile working through each of the 81 portions at a time - maybe one each week. Then we will have it done by a year.

The Lau translation has been pretty reliable in the past, so I'll be copy-pasting it here.

The way that can be spoken of
Is not the constant way;
The name that can be named
Is not the constant name.

The nameless was the beginning of heaven and earth;
The named was the mother of the myriad creatures.

Hence always rid yourself of desires in order to observe its secrets;
But always allow yourself to have desires in order to observe its manifestations.

These two are the same
But diverge in name as they issue forth.
Being the same they are called mysteries,
Mystery upon mystery -
The gateway of the manifold secrets.

The opener of the text.

I feel that it sets the foundation that the Dao is that of change and flux - reflected in that adage, "The only constant is change, (and that, too, changes)."

There's a bit of zen in the third block - but, it can be also viewed as "don't go looking for the Dao - if you go looking for it, you won't find it."
Insofar as desire is that want to seek the Dao. Since the core is a sort of "simple action" or even "action without doing."

This eschewing of category and names and pouring of all into mysteries, I feel, is what is being expressed here.
