தன் பதவியில் செயல்திறம் உடையவன் நிர்வாகத்திற்கு வேண்டியவனாக இருக்க, அவனை ஒழிக்க எண்ணிக் கோள் மூட்டுவார் சொல்லை நிர்வாகம் கேட்குமானால் அந்த நிர்வாகத்தை விட்டுச் செல்வத் திருமகள் நீக்குவான்.

எடுத்த காரியத்தை முடிப்பதில் கண்ணும் கருத்துமாக இருப்பவரின் உறவைத் தவறாக எண்ணுபவரை விட்டுப் பெருமை அகன்று விடும்

மேற்க்கொண்ட தொழிலில் எப்போதும் முயற்சி உடையவனின் உறவைத் தவறாக நினைக்கும் தலைவனை விட்டுச் செல்வம் நீங்கும்.

Prosperity will leave (the king) who doubts the friendship of the man who steadily labours in the discharge of his duties

Kural 519 emphasizes the importance of trust in any relationship, particularly in the context of a king and his dutiful subjects or officials. It states that prosperity will abandon a ruler who unjustly doubts the loyalty of a person who is diligently fulfilling his duties. This verse illustrates the concept that mistrust in a trustworthy person can lead to one's downfall. When a person is consistently working hard and fulfilling his responsibilities, doubting his loyalty or intentions can be counterproductive and damaging. In the case of a king, this could lead to the loss of a valuable asset, potential discord within the kingdom, and eventually, a decline in prosperity. The Kural warns leaders, or anyone in a position of authority, to be judicious in their judgement of others' loyalty and commitment. Misplaced suspicion can lead not only to the loss of valuable allies, but also to the overall well-being and prosperity of the kingdom or organization. Furthermore, this verse underscores the value of trust in a successful leadership. It highlights that a good leader should be able to discern, trust, and value his diligent and committed subjects, as their contribution is essential for the prosperity and success of his reign. In conclusion, Kural 519 teaches the detrimental consequences of unwarranted suspicion and emphasizes the critical role of trust in maintaining a prosperous and harmonious rule.
