बाधतीर्थाश्चैताः कार्या राजद्विष्टकारिणां तरणभयात् ॥ कZ_०२.२८.१४ ॥
bādhatīrthāścaitāḥ kāryā rājadviṣṭakāriṇāṃ taraṇabhayāt
बाधित-नियन्त्रित-तीर्थानि एतानि राजद्विष्टकारिणां तरणभयात् कारयेत्।
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.
