Everything that irritates us about others can lead us to an understanding of ourselves.Carl Jung
When someone really upsets you, once or repeatedly, that person has probably acted in violation of one of your core values.
There are always going to be people in your life who you don’t particularly care for their company. Fine, that’s life. What is not fine is if you spend too much time ruminating on the fact that you don’t like them. That is not good for you or your karmic bank account. I can be so guilty of this.
Identify your core value that is being violated to bring yourself peace of mind.
Here is one example of a difficult couple from a time in my life. From my perspective, this couple had a strong essence of arrogance and superiority. I also found them to be a caricature of success and beauty. My frustration with them was almost constant for a time due to their proximity and shared friendships. I needed to get to the root of the issue for my own peace of mind. After meditating several times on which of my core values was being violated, the conclusion finally dawned on me that they were not authentic. That realization made authenticity a newly identified core value of mine. In hindsight, I could see the role authenticity had played in my life in many situations and relationships.
Now when I encounter other situations or people that ruffle me due to lack of authenticity, I acknowledge it with more level emotions and a greater understanding of self.
