எத்தனை வகை உறுதி உடையவராக இருந்தாலும் செயல் உறுதி இல்லாதவரை உயர்ந்தோர் மதிக்கமாட்டார்.

எவ்வளவுதான் வலிமையுடையவராக இருப்பினும் அவர் மேற்கொள்ளும் செயலில் உறுதியில்லாதவராக இருந்தால், அவரை உலகம் மதிக்காது

வேறு எத்தகைய உறுதி உடையவராக இருந்தாலும், செய்யும் தொழிலில் உறுதி இல்லாதவரை உலகம் விரும்பிப் போற்றாது.

The great will not esteem those who esteem not firmness of action, whatever other abilities the latter may possess

Thiru Kural 670 emphasizes the importance of consistency and determination in one's actions. Even if an individual possesses various talents or abilities, the world will not value or respect them if they lack firmness and steadfastness in their actions. This kural underscores the fact that it is not just talent or ability that matters, but the consistent application of these talents in a determined and unwavering manner. This concept aligns with many cultures' emphasis on the virtue of perseverance. It is often not the most talented or smartest who succeed, but those with the most grit and determination to persist in their efforts, regardless of the challenges they face. The kural is a reminder that the world values deeds and actions that are backed by a strong will and unwavering commitment. In essence, the verse encourages one to not just possess talents or abilities, but also to apply them consistently and persistently, thereby achieving both personal success and societal respect.
