Spirit tells me that acceptance is contentment.

How can I feel content about accepting something
that I can’t change?

What else would you feel?

Defeated.

In losing a battle you know or believe that
you never could win?

What else could I feel?

Satisfied with yourself that you did, if you did,
everything you could do to win.

And satisfaction is as contentment?

In this case, yes

Are we referring to a specific case?

Yes, and no.

As particular and general?

Yes.
