उद्योगपर्व — अध्याय 33: धृतराष्ट्र-विदुर संवादः (विदुरनीतिः)
अभ्यावहति कल्याणं विविधं वाक् सुभाषिता | सैव दुर्भाषिता राजन्ननर्थायोपपद्यते
abhyāvahati kalyāṇaṃ vividhaṃ vāk subhāṣitā | saiva durbhāṣitā rājann anarthāyopapadyate ||
राजन्! सुभाषित वाणी अनेक प्रकारचे कल्याण घडवते; पण तीच वाणी जर कटु व असंयत शब्दांत बोलली, तर ती महान् अनर्थाचे कारण ठरते.
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.
