Now, there's a dark side of the force. Therefore the Force at a necessary and sufficient minimal level is non-dark. And that's the reference - non-dark

The Dark side as geometric, optic or umbral difference on spectrum or continua is the other but with a One (the Force) without ascription or qualia. The force is uninscribed by either geometry or photosensitive categorical classification.

The Force as uninscribed is centre as such and arguably a non-centre.

A non-centre centre. The Double which is not one. A unbraided recursion.

Do not doubt the power of the Force!

Or as the Dark side sayeth - I find your lack of faith disturbing.
