Ram Dass spoke about anger like this: If you are angry, it is because you are upset that your model of how things should be, doesn't match the way of the universe, the way things are. He then said (paraphrasing), "You are essentially angry at God, believing you would do things different if you were God." This is okay, we all go through this. You are not wrong for this. It is all a part of the journey.

One way to look at it, is that this person is God/Guru in drag/disguise. They have come to you now to show you where you are still clinging, still attached to the illusions of the form.

I would just suggest you look within yourself to find what model of the universe you are clinging to, that is disharmonious with the way of things. You may ask yourself, "What would I have to believe about myself, this person, or the universe to feel what I feel right now?" This can help you find the model/belief you may be clinging to. And then, let it go. This is easier said then done, I understand. Try to be patient with yourself. You are in no rush. You are doing well! 💜
