बाधतीर्थाश्चैताः कार्या राजद्विष्टकारिणां तरणभयात् ॥ कZ_०२.२८.१४ ॥
bādhatīrthāścaitāḥ kāryā rājadviṣṭakāriṇāṃ taraṇabhayāt
应设立受阻/受控的渡口,以使反王者畏惧并难以进行非法渡越,从而起到威慑作用。
A deliberately controlled chokepoint—through physical obstruction and supervision—to regulate who can cross and to raise the cost of hostile movement.
Ferries facilitate lawful movement; controlled fords restrict unlawful movement—together forming a dual system of enablement and denial.
