Questions about self-righteousness and humility

Self-righteousness–the antithesis of a humble person is not a good trait to have.

A core trait of an (outwardly) righteous person is humility.

So, does self-righteousness mean you are not a righteous person?

If I am a righteous person (objectively,) but I also think that I am a righteous person, is that a lack of humility? Is that self-righteousness creeping in? And if it is, am I even righteous anymore?

Does the humble person know they’re humble? Are they allowed to acknowledge it? Or would that be a lack of humility?

Would it be easier to be open to the critique and suggestions of others if we had a more open mind and didn’t think we knew the best way always? Humility leads you to have a mind that is open to the critique and suggestions of others.

Humility also will give you the confidence to live at peace when you are criticized. Even if you do take the attack personally, you’re not so self-righteous that a personal attack feels outrageous. It’s a peaceful thing.

Of course, you do need to have a strong and sharpened mind to know which critique you will take and which critique is complete rubbish. A strong mind can also rebuff (or completely ignore) the critique that falls in the category of personal attack.

I have questions about where self-righteousness begins and what bearing that has on personal humility AND the connection that has to mental/emotional stability.
