[Yoda]

I am starting to feel that balance is actually the very core of the swing and hence fully deserving it place as an essential ... not merely some afterthought... but as an active conscious part which we should seek to use.

The Golfing Machine begins and ends with Balance.

Per the 45-item Mechanical Checklist of All Strokes (12-3-0):

12-3-#1 Stance and Balance;

12-3-#45 Body Position and Balance.

And per 1-L:

"Off-balance force is notoriously erratic."
