sa dvādaśadvāro yuktodakabhramacchannapathaḥ
सः द्वादशद्वारः स्यात्, युक्तोदकभ्रमः, छन्नपथश्च।
Gates enable controlled commerce and movement; waterworks add siege resistance; covered routes allow secure internal logistics and emergency redeployment.
Control: multiple gates distribute traffic yet remain regulated choke-points for inspection, tolls, and security screening.
