उद्योगपर्व — अध्याय 33: धृतराष्ट्र-विदुर संवादः (विदुरनीतिः)
कर्णिनालीकनाराचान् निर्हरन्ति शरीरत: । वाक्शल्यस्तु न निर्हर्तु शक्यो हृदिशयो हि सः
karṇinālīkanārācān nirharanti śarīrataḥ | vākśalyas tu na nirhartu śakyo hṛdiśayo hi saḥ ||
முள்ளுள்ள, இரும்பு முனையுடைய அம்புகளை உடலிலிருந்து இழுத்தெடுக்கலாம்; ஆனால் கொடுஞ்சொல்லின் முள் எடுக்க இயலாது—அது இதயத்தில் தங்கிவிடுகிறது.
विदुर उवाच
Physical injuries may heal when the weapon is removed, but harsh words become an inner ‘thorn’ that remains in the heart; therefore one should practice restraint, truthfulness, and gentleness in speech as part of dharma.
In the counsel of Vidura during the tense pre-war negotiations of the Udyoga Parva, he warns that verbal cruelty causes lasting damage—often more enduring than bodily wounds—urging ethical conduct and measured speech amid conflict.
