उद्योगपर्व — अध्याय 33: धृतराष्ट्र-विदुर संवादः (विदुरनीतिः)
क्षुद्राक्षेगेव जालेन झषावपिहितावुरू । कामश्न राजन् क्रोधश्व तौ प्रज्ञानं विलुम्पत:
kṣudrākṣegeva jālena jhaṣāv apihitāv urū | kāmaś ca rājan krodhaś ca tau prajñānaṁ vilumpataḥ ||
রাজন! যেমন সূক্ষ্ম ছিদ্রযুক্ত জালে ধরা দুই বৃহৎ মাছ ছটফট করে জাল ছিঁড়ে ফেলে, তেমনি কাম ও ক্রোধ—এই দুই—মানুষের প্রজ্ঞা হরণ করে।
विदुर उवाच
Desire and anger, acting together, steal prajñā—clear discernment—so one should restrain these impulses, especially in positions of power where a single clouded decision can cause widespread harm.
In Udyoga Parva, Vidura is counseling the king during the tense pre-war negotiations. He uses a vivid simile—two big fish trapped in a fine-meshed net—to illustrate how powerful inner impulses (kāma and krodha) can break through restraint and ruin judgment.
