Final answer:
The correct answer is 3. The 9th stanza implies that knowing one's own faults leads to forgiveness of others' faults, demonstrating how self-awareness fosters empathy and reduces the propensity to judge.
Step-by-step explanation:
The 9th stanza suggests that a person who knows his own faults will forgive those of others. This reflects a common theme in literature and philosophy that self-awareness leads to compassion. To fully understand this concept, one should consider that acknowledging one's own imperfections often prompts a sense of empathy. When we are acutely aware of the challenges we face in striving for personal betterment, we are more likely to empathize with others who also struggle.
This process of self-reflection can help diminish the sting of judgment. Instead of casting aspersions on someone else's actions, an individual might consider how they have faltered similarly and extend forgiveness rather than criticism. It's a testament to the old adage, 'To err is human; to forgive, divine.' Essentially, it aligns with the idea that understanding our own failings allows us to be more forgiving of the failings in others.
