उद्योगपर्व — अध्याय 33: धृतराष्ट्र-विदुर संवादः (विदुरनीतिः)
अभ्यावहति कल्याणं विविधं वाक् सुभाषिता | सैव दुर्भाषिता राजन्ननर्थायोपपद्यते,राजन! मधुर शब्दोंमें कही हुई बात अनेक प्रकारसे कल्याण करती है; किंतु वही यदि कट शब्दोंमें कही जाय तो महान् अनर्थका कारण बन जाती है
abhyāvahati kalyāṇaṃ vividhaṃ vāk subhāṣitā | saiva durbhāṣitā rājann anarthāyopapadyate ||
Vidura said: “O King, speech that is well-spoken brings many kinds of welfare and benefit. But that very same message, when expressed in harsh and ill-chosen words, becomes a cause of great harm.”
विदुर उवाच
The ethical force of a message depends not only on its content but on its manner of expression: gentle, well-chosen words can bring welfare, while the same truth delivered harshly can provoke injury, resentment, and ruin.
In Udyoga Parva, Vidura is advising the king (Dhṛtarāṣṭra) during the tense pre-war negotiations, emphasizing prudent, dharmic communication so that counsel and diplomacy do not turn into conflict through abrasive speech.
