இயல்பான நல்லறிவு, காண்பவர் விரும்பும் தோற்றம், பலரோடும் பலகாலமும் ஆராய்ந்த கல்வி இம்மூன்றையும் நிறையப் பெற்றுச் சொல்ல வேண்டியதைத் தானே எண்ணிச் சொல்லும் திறம் படைத்தவன் தூதர் பணிக்குச் செல்க.

தூது உரைக்கும் செயலை மேற்கொள்பவர் அறிவு, தோற்றப் பொலிவு, ஆய்ந்து தெளிந்த கல்வி ஆகிய மூன்றும் நிறைந்தவராக இருத்தல் வேண்டும்

இயற்கை அறிவு, விரும்பத்தக்கத் தோற்றம், ஆராய்ச்சி உடையக் கல்வி ஆகிய இம் மூன்றின் பொருத்தம் உடையவன் தூது உரைக்கும் தொழிலுக்குச் செல்லலாம்.

He may go on a mission (to foreign rulers) who has combined in him all these three viz, (natural) sense, an attractive bearing and well-tried learning

This verse from the Thirukkural emphasizes the qualities required in an individual who is entrusted with the important task of being a diplomatic envoy or a messenger. It states that there are three key attributes one should possess to effectively fulfill this role. Firstly, he should have 'natural sense' or innate intelligence. This intelligence should allow him to understand complex situations, perceive nuances, and make effective decisions. He should be able to understand the underlying implications of words and actions which may not be explicitly stated. Secondly, he should have an 'attractive bearing'. This does not just refer to physical attractiveness, but also to charm, etiquette, and charisma. He should be able to present himself well, communicate effectively, and engage gracefully with others. This quality is important as it can influence how well received his messages are. Lastly, he should have 'well-tried learning'. This implies a deep and broad understanding of various subjects and domains. He should be well-versed in the language, culture, customs, and norms of both his own and the foreign lands he will interact with. This knowledge should be well-tested and proven to be reliable. The verse signifies that if an individual embodies these three qualities, he is well-equipped to undertake diplomatic missions. These qualities ensure that he can represent his ruler or country effectively, navigate diplomatic relations tactfully, and promote peace and understanding between nations.
