यत्र बाह्या बाह्यानुपजपन्ति अभ्यन्तरानभ्यन्तरा वा तत्रैकान्तयोग उपजपितुः सिद्धिर्विशेषवती ॥ कZ_०९.५.१७ ॥
yatra bāhyā bāhyān upajapanti abhyantarān abhyantarā vā tatraikāntayoga upajapituḥ siddhir viśeṣavatī
Là où des étrangers poussent des étrangers, ou des gens de l’intérieur poussent des gens de l’intérieur, une opération étroitement ciblée (à voie unique) y procure à l’instigateur un succès particulièrement efficace.
Subversion is more effective when the persuader and target share the same social/organizational category (outsider-to-outsider or insider-to-insider), because trust and access are higher.
It implies the state must disrupt same-category influence channels (peer networks) and avoid letting a single uninterrupted line of persuasion continue.
