What is Pride?

I can recall so many religious quotes warning against pride... I can remember references thrown around during my college days at Thomas Aquinas. "The worst of these is Pride..." Let's see, what can I find online, Oh my!
The mother of all:
Pride is called the "birth mother" of all the deadly sins. Pride is the worst of sins because it involves a full-scale inversion of reality. If sanity is an ordering of one's life in harmony with reality...

The father of all:
Pride is rightly considered to be "the father of all sin ," 

David Hawkins:
They have been earned and have a realistic foundation. Pride as a spiritual defect refers to pridefulness as an attitude and a positionality. It is an arrogance that can apply to beliefs, thoughts, opinions, and the general attitude of being better than others. This is an over evaluation of self-worth and is commonly referred to as egotism.

As a Position in the levels of Consciousness: Pride – The first level where you start to feel good, but it’s a false feeling. It’s dependent on external circumstances (money, prestige, etc), so it’s vulnerable. Pride can lead to nationalism, racism, and religious wars. Think Nazis. A state of irrational denial and defensiveness. Religious fundamentalism is also stuck at this level. You become so closely enmeshed in your beliefs that you see an attack on your beliefs as an attack on you.

I had my final session with April creating meditations to release the lower frequencies of emotion on the Hawkins' scale. After a bit of study and reading I noticed that while Pride is the highest of the low vibrations it is the beginning of the worst... All the lower vibrations have their root in pride, looking good, being right and being attached to "things" and thus afraid or sad when "things" are gone or may be gone... avoiding, etc. Curious that... I found some true freedom in the exercise of letting go of all I think I know and believe... all my attachments and expectations basically. Like I've been saying these same things for months, years, yet here we go, another level of relatedness and awareness to bring it home. Captain Obvious I guess. I should cease to be surprised by these revelations. 

Of course the lesson presents in several different ways at once. I have been experiencing very odd and very severe muscle and joint pain recently. Just at night, mostly and moving around. One night my right calf the next my left thumb, then my right wrist or left bicep. It comes on around 8pm or later and disappears (usually) around 9am the next day. I am in the process of attempted to partner with health care "professionals" to discover the cause... it's NOT COVID... Anyway, my go to first resource is Heal Your Body by Louise Hay her feedback for knees and joints in general: 
Problem: Joints
Probable Cause: Represents changes in direction in life and the ease of these movements
New Thought Pattern: "I easily flow with change. My life is Divinely guided and I am always going in the best direction."

Problem: Knees (they hurt the most for the first couple weeks)
Probable Cause: Represents Pride & Ego. Inflexibility & Fear (see joints)
New Thought Pattern: "Forgiveness, Understanding. I am flexible and flowing. I bend and flow with ease. All is well."

Problem: Wrist
Probable Cause: Represents movement and ease.
New Thought Pattern: "I handle all my experiences with wisdom, with love and with ease."

​Ok... got it... Thanks for the insights and stay tuned.
