செய்யக்கூடாதவற்றைச் செய்தாலும் செய்ய வேண்டியவற்றைச் செய்யாமல் விட்டாலும் அழிவு வரும்.

செய்யக் கூடாததைச் செய்வதால் கேடு ஏற்படும்; செய்ய வேண்டியதைச் செய்யாமல் விட்டாலும் கேடு ஏற்படும்

ஒருவன் செய்யத்தகாத செயல்களைச் செய்வதனால் கெடுவான், செய்யத்தக்க செயல்களை செய்யாமல் விடுவதனாலும் கெடுவான்.

He will perish who does not what is not fit to do; and he also will perish who does not do what it is fit to

This Thiru Kural verse, Kural 466, essentially talks about the consequences of actions, whether they are actions committed or actions omitted. It underscores the importance of discerning what is right and wrong, and the need to act accordingly. In the first part of the verse, "He will perish who does not what is not fit to do", the poet emphasizes that engaging in actions that are deemed unfit or wrong can lead to one's downfall. This could be anything that goes against moral, ethical, societal or personal principles. The consequences of such actions can be detrimental, leading to ruin or suffering. The second part of the verse, "he also will perish who does not do what it is fit to do", underscores that inaction in the face of duty or responsibility can also lead to negative consequences. Sometimes, not doing what is necessary or expected can be just as damaging as doing what is wrong. This could refer to failing to uphold responsibilities, neglecting duties, or refraining from taking action when it's needed. Overall, this verse highlights the importance of mindful action. It encourages us to be aware of our actions and their potential consequences, and to strive to do what is right while refraining from what is wrong. It also serves as a reminder that inaction can be just as consequential as action, and that we must fulfill our duties and responsibilities to the best of our abilities.
