Here's another example,
Argument, is often aimed at a person's goal that one persons current idea will prevail.( Their own)
If that happens ,accord will be reached, ( So the goal of argument could be said to be accord, if things get that far along).
person who gains the 'win', ends up with the original conclusions they had.( no real gain) And the who was rectified, gains a better perspective.
So the teachings are not other-worldly, they are not magic, They are a clarification of wise perspective,,it is only confusing looking, to one holding bungled ideas.
Contending, 'by not contending' ,,, can be digging ones heels in, holding ones tongue... So as to not risk altering their views,nor be subject to attack.
Or ,it can be actively chatting without trying to find ones current opinions correct.
Keeping ego out of it, you make your points, you make friends, you pass time pleasantly , and you're open to advantageous adaptation.
This is the 'contending ,without contention'.
You let go of the desire to prevail, and open yourself to improvement.
In the next argument you will be offering more.
Apparently that's not fun though.
