அவரவர் சொல் திறந்தாலேயே நன்மையும், தீமையும் வருவதால், பேசும் பேச்சில் பிழை வராமல் விழிப்புடன் பேசுக.

ஆக்கமும் அழிவும் சொல்லால் ஏற்படும் என்பதால், எந்தவொரு சொல்லிலும் குறைபாடு நேராமல் கவனமாக இருக்க வேண்டும்

ஆக்கமும் கேடும் சொல்லுகின்ற சொல்லால் வருவதால் ஒருவன் தன்னுடைய சொல்லிற்க்கு தவறு நேராமல் காத்துக்கொள்ள வேண்டும்

Since (both) wealth and evil result from (their) speech, ministers should most carefully guard themselves against faultiness therein

Kural 642 emphasizes the importance of mindful speech, particularly for those in positions of power and influence like ministers. According to this Kural, both prosperity and disaster can stem from one's words. The power of speech is such that it can either create or destroy, bring fortune or misfortune. Therefore, it is vital for people, especially those entrusted with the responsibility of advising or governing others, to exercise caution in their speech. They should guard against any flaw or error in their words as faulty speech can lead to unfortunate consequences. The verse highlights the need for careful thought before speaking, promoting the idea of mindful communication. This principle is not only applicable to ministers but to everyone, as our words hold the power to shape our lives and the world around us. This verse also underscores the belief in the power of the spoken word prevalent in Tamil culture and many other cultures worldwide. The verse suggests that wise and careful speech can lead to prosperity, while careless or harmful words can lead to downfall or disaster. Therefore, it encourages individuals to be mindful of their words, speaking thoughtfully and responsibly.
