निकुम्भिला-यज्ञविघ्नः — Vibhishana’s Counsel and Lakshmana’s March to Nikumbhila
स एषसहसैन्येनप्राप्तःकिलनिकुम्भिलाम् ।यद्युततिष्ठेत्कृतंकर्महतान्सर्वांश्चविद्धिनः ।।6.85.13।।
nikumbhilām asamprāptam āhuta-agniṃ ca yo ripuḥ | tvām ātāyinaṃ hanyād indra-śatroḥ sa te vadhaḥ ||6.85.14||
varo datto mahābāho sarva-lokeśvareṇa vai | ity evaṃ vihito rājan vadhas tasyaiṣa dhīmataḥ ||6.85.15||
So long as you have not reached Nikumbhilā and the fire-offering has not been made, that enemy—Indra’s foe—can strike you down. Such a boon, O mighty-armed king, was indeed granted to him by the Lord of all worlds; thus has the manner of that wise one’s slaying been ordained.
"Indrajith has reached Nikumbhilam accompanied by the army. If he completes the sacrifice and comes from there after completion of the sacrifice, know that we are all killed.
Dharma includes understanding the moral mechanics of boons and conditions: power operates within stated limits, and righteous action must respond intelligently to those conditions.
Vibhīṣaṇa explains Indrajit’s conditional advantage: before the rite is disrupted, he can become deadly; therefore the allies must intervene immediately.
Responsible leadership through knowledge: Vibhīṣaṇa provides precise intelligence so that force is applied justly and effectively.
