कृच्छ्रोपजापा हि बाह्यानामभ्यन्तरास्तेषामितरे वा ॥ कZ_०९.५.०७ ॥
kṛcchropajāpā hi bāhyānām abhyantarās teṣām itare vā
收买外部之人很困难——(最好)由其内部之人来做,或否则由其他(适合此事者)来做。
Access, trust, and cultural/political distance make recruitment harder; insiders have credibility and proximity.
Non-insiders who still have leverage—e.g., intermediaries, allied agents, or those with shared interests/resources enabling contact.
