In the excerpt from "Grande Sertão: Veredas" by João Guimarães Rosa, the author highlights the complexities of anger. He suggests that anger can sometimes feel necessary, but ultimately, it should not have authority over our emotions and thoughts. Allowing ourselves to remain angry gives power to the person we are upset with, undermining our own agency and sovereignty.

Rosa emphasizes the importance of self-control, implying that managing anger is crucial for maintaining our mental and emotional independence. When we hold onto anger, we risk letting it dictate our feelings and perceptions, which can lead to a lack of emotional clarity and personal freedom.
