I came across a theory by u/Andorli named The true meaning behind "Beta" and "Alpha" polarity.

fun little post and toward the end he wrote;

"As a final advice there is an interesting concept called congruence which is alignment of intentions-thoughts-actions, I will not go into that concept in this post but I urge you to research it"

So... What is this congruence which is spoken of, and what are some books/ videos which can illuminate this for me?
