எல்லாராலும் விரும்பத்தக்க நாகரிகத்தை விரும்புபவர், தமக்கு நெருக்கமானவர் நஞ்சையே தருகிறார் என அறிந்தும் கண்ணோட்டம் காரணமாக அதை உண்டு அவருடன் பழகுவர்.

கருணை உள்ளமும் பண்பாடும் உள்ளவர்கள், தம்முடன் பழகியவர்கள் நஞ்சு கொடுத்தாலும் அதை அருந்திக் களிப்படைவார்கள்

எவராலும் விரும்பத்தக்க நாகரிகமான கண்ணோட்டத்தை விரும்புகின்றவர், பழகியவர் தமக்கு நஞ்சு இடக்கண்டும் அதை உண்டு அமைவர்.

Those who desire (to cultivate that degree of) urbanity which all shall love, even after swallowing the poison served to them by their friends, will be friendly with them

Kural 580 explores the concept of urbanity, or civility, which is a quality of being courteous and considerate. From a broader perspective, it refers to a high degree of social refinement. The verse states that those who desire to cultivate such a level of urbanity that everyone admires, will maintain amicability even with those who have wronged them. The metaphor of swallowing poison served by friends is a profound one. It suggests an act of betrayal or harm done by those close to us. Yet, the verse asserts that true urbanity lies in the ability to forgive such transgressions, assimilate them without retaliation, and continue to be friendly. This metaphorical 'swallowing of poison' essentially represents the act of enduring pain or insult without seeking revenge or harboring resentment. So, the verse emphasizes the virtue of forgiveness and patience in maintaining social harmony. This is a significant principle in Tamil culture where the value of maintaining relationships and social cohesion is highly esteemed. It implies that the magnanimity to forgive and forget is the sign of a refined person, who is loved and respected by all. The moral lesson from the verse is to uphold dignity and grace in all circumstances, even in the face of betrayal or harm.
