लाङ्गूलदाह-पर्यटनम् (The Burning Tail and the Parade through Laṅkā)
यदि तावत्समुद्रस्य मैनाकस्य च धीमतः।।5.53.37।।रामार्थं सम्भ्रमस्तादृक्किमग्निर्न करिष्यति।
yadi tāvat samudrasya mainākasya ca dhīmataḥ ||5.53.37|| rāmārthaṃ sambhramas tādṛk kim agnir na kariṣyati |
If the ocean and the wise Maināka could show such eager concern for Rāma’s cause, then what could the Fire-god not do for that same cause?
'If the anxiety of the ocean and the wise Mainaka mountain is to serve Rama what is it that the fire cannot do?
Dharma is collective alignment with righteousness: even nature and deities cooperate when the goal is just, reinforcing faith in moral order.
Hanumān reasons that since the ocean and Maināka aided his mission for Rāma, Fire too can be restrained for that mission.
Hanumān’s confidence rooted in dharma (not arrogance): he trusts the cause of Rāma to command support.
