हनूमदुपदेशः रावणस्य च कोपः (Hanuman’s Counsel to Ravana and Ravana’s Wrath)
यां सीतेत्यभिजानासि येयं तिष्ठति ते वशे।।।।कालरात्रीति तां विद्धि सर्वलङ्काविनाशिनीम्।
yāṃ sītety abhijānāsi yeyaṃ tiṣṭhati te vaśe; kālarātrīti tāṃ viddhi sarvalaṅkāvināśinīm.
She whom you recognize as “Sita,” though she now stands within your power—know her as Kālarātri, the Night of dissolution, destined to destroy all Lanka.
"Sita who is under your custody is no ordinary lady. She is indeed the dark night of dissolution, destroyer of entire Lanka. Know this.
Dishonoring a virtuous person invites ruin; dharma protects the innocent and turns their suffering into the downfall of the oppressor.
Hanuman reframes Sita not as a helpless captive but as a cosmic force whose violation will precipitate Lanka’s destruction.
Sita’s inner power rooted in purity and steadfast righteousness, portrayed as spiritually and morally invincible.
