Step-by-step explanation:
The question refers to the negative emotions and behaviors that one should strive to eliminate from their lives. These include bitterness, rage, anger, brawling, and slander. It is essential to let these abusive customs disappear. As the provided quotes suggest, focusing on personal growth, positive traditional values, and correcting one's judgment and maxim of life are ways to overcome grief and negative dispositions. Additionally, the concept of working for another's gain and eschewing pride and hate aligns with the idea of abandoning destructive emotions and actions.

To get rid of all bitterness, rage and anger, brawling and slander is to embrace a life that seeks the benefit of others and maintains serenity in the face of external pressures. This approach promotes a community-centric view which echoes the philosophy of 'the White Man's burden' in a call for selflessness and helping to solve issues of famine and sickness, despite it being a controversial poem that carries the baggage of colonialism.
