Description of Lanka’s Fortifications and Forces

جب وہاں دشمن کی فوج آ پہنچتی تو ان گذرگاہوں کی حفاظت مضبوط کر دی جاتی؛ اور انہی یانتروں کے ذریعے راستے ہر طرف سے خندقوں میں کھینچ کر گرا دیے جاتے، تاکہ داخلہ بند ہو جائے۔
"When the enemy arrives, the engines all over the moats lift the bridges making entry impossible for enemy armies."
The verse underscores protective duty: defenses are activated specifically when aggression appears, suggesting restraint paired with readiness—an ethical balance in the use of force.
The mechanism of Laṅkā’s defenses is explained: bridges/crossings can be withdrawn or dropped into the moat to block invading armies.
Alert preparedness—being ready to respond effectively at the moment of threat.
