Shloka 6.48.16
सीताविलापः—त्रिजटासान्त्वनं च (Sita’s Lament and Trijata’s Consolation)
ननुवारुणमाग्नेयमैन्द्रंवायव्यमेवच ।अस्त्रंब्रह्मशिरश्चैवप्रत्यपद्यताम् ।।।।
nanu vāruṇam āgneyam aindraṁ vāyavyam eva ca | astraṁ brahmaśiraś caiva pratyapadyatām ||
Surely the two Rāghavas knew how to wield Varuṇa’s weapon, Agni’s weapon, Indra’s weapon, and Vāyu’s as well—indeed, even the Brahmaśiras weapon. Why, then, did they not counter it?
"Raghavas knew to use Varuna's weapons, fire god's weapons, Indra's also, even wind god's and Brahma's weapons. Why have they not used?"
The verse implicitly contrasts righteous strength with helplessness under deception: even great capability can appear defeated when adharma (unfair concealment and trickery) distorts the visible outcome.
Sītā, hearing or imagining news that Rāma and Lakṣmaṇa have been struck down, wonders why they did not respond with their known divine weapons.
Rāma and Lakṣmaṇa’s martial mastery (śaurya and astravidyā) is emphasized—Sītā’s grief arises precisely because she knows their competence.
