उद्योगपर्व — अध्याय 33: धृतराष्ट्र-विदुर संवादः (विदुरनीतिः)
यः पज्चाभ्यन्तराउ्छत्रूनविजित्य मनोमयान् । जिगीषति रिपूनन्यान् रिपवो5भिभवन्ति तम्,जो चित्तके विकारभूत पाँच इन्द्रियरूपी भीतरी शत्रुओंको जीते बिना ही दूसरे शत्रुओंको जीतना चाहता है, उसे शत्रु पराजित कर देते हैं
yaḥ pañcābhyantarān śatrūn avijitya manomayān | jigīṣati ripūn anyān ripavo 'bhibhavanti tam ||
ਜੋ ਮਨ ਤੋਂ ਉਪਜੇ ਪੰਜ ਅੰਦਰਲੇ ਵੈਰੀਆਂ ਨੂੰ ਜਿੱਤੇ ਬਿਨਾਂ ਹੀ ਬਾਹਰਲੇ ਵੈਰੀਆਂ ਨੂੰ ਜਿੱਤਣਾ ਚਾਹੁੰਦਾ ਹੈ, ਉਸ ਨੂੰ ਉਹੀ ਵੈਰੀ ਆਖ਼ਰਕਾਰ ਹਰਾ ਦਿੰਦੇ ਹਨ।
विदुर उवाच
External victory is unreliable without inner victory: one must first subdue the five internal, mind-born enemies (often understood as the unruly senses and their impulses). Otherwise, a person becomes vulnerable and is defeated despite aiming to conquer others.
In Udyoga Parva, Vidura is giving moral and political counsel. Here he warns that a ruler or aspirant who tries to overcome opponents without first mastering inner passions and sense-driven tendencies will be overpowered—because inner disorder undermines judgment, discipline, and strategy.
