रावणवधोत्तरं विभीषणशोकः—क्षत्रधर्मोपदेशः (Vibhishana’s Lament after Ravana’s Fall; Instruction on Kshatriya-Dharma)
धृतिप्रवालःप्रसह्याग्य्रपुष्पस्तपोबलश्शौर्यनिबद्धमूलः ।रणेमहान्राक्षसराजवृक्षःसम्मर्दितोराघवमारुतेन ।।।।
dhṛtipravālaḥ prasahyāgryapuṣpas tapobalaś śauryanibaddhamūlaḥ |
raṇe mahān rākṣasarājavṛkṣaḥ sammardito rāghavamārutena ||
In battle, the great ‘tree’ that was the rākṣasa-king—its shoots being steadfastness, its foremost blossoms being stubborn force, its vigor born of tapas, and its roots bound fast by valor—was crushed by the gale that was Rāghava.
"The great tree in the form of Rakshasa king, with its firmness as leaves, stubbornness as its blossom, austerity as strength, valour as strong roots, was crushed by the tempest of Raghava in the battlefield."
Dharma ultimately overcomes adharma: even formidable power, discipline, and valor become futile when rooted in unrighteous aims.
A metaphorical description of Rāvaṇa’s defeat portrays him as a mighty tree felled by Rāma as a tempest.
Rāma’s righteous might—power exercised as the instrument of dharma, decisive and world-restoring.
