बाधतीर्थाश्चैताः कार्या राजद्विष्टकारिणां तरणभयात् ॥ कZ_०२.२८.१४ ॥
bādhatīrthāścaitāḥ kāryā rājadviṣṭakāriṇāṃ taraṇabhayāt
Hendaklah diwujudkan tempat-tempat lintasan (ford) yang dihalang/dikawal, untuk menakutkan dan menghalang mereka yang bertindak menentang raja, dengan menjadikan penyeberangan haram itu menakutkan/sukar.
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.
