स द्वादशद्वारो युक्तोदकभ्रमच्छन्नपथः ॥ कZ_०२.४.०२ ॥
sa dvādaśadvāro yuktodakabhramacchannapathaḥ
उस (नगर/दुर्ग) में बारह द्वार हों, जल-परिक्रमा (खाई/जल-व्यवस्था) से युक्त हो, और छिपे/आवृत मार्ग हों।
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.
