विभीषणोपदेशः (Vibhīṣaṇa’s Counsel to Rāvaṇa and the Rākṣasa Court)
प्रहस्त: राजाचमहोदरश्चत्वंकुम्भकर्णश्चयथाऽर्थजातम् ।ब्रवीतरामंप्रतितन्नशक्यंयथागतिस्स्वर्गमधर्मबुद्धेः ।।।।
prahastaḥ rājā ca mahodaraś ca tvaṃ kumbhakarṇaś ca yathārtha-jātam |
bravīta rāmaṃ prati tan na śakyaṃ yathā gatiḥ svargam adharma-buddheḥ ||
Prahastha, the king, Mahodara, you, and Kumbhakarṇa—whatever you devise against Rāma cannot be accomplished; just as one of unrighteous mind does not attain heaven.
"That which you intend to accomplish against Rama is not possible either for you or the king and even for Kumbhakarna and Mahodara, just as heaven is not obtained by the unrighteous people," said Vibheeshana.
Dharma is presented as the condition for true success: unrighteous intent cannot yield the highest goal (svarga), and similarly adharma-driven aggression cannot defeat a dharmic hero like Rāma.
Vibhīṣaṇa counters the warlike boasting in Rāvaṇa’s court, warning that plans to oppose Rāma are futile when rooted in unrighteousness.
Truthfulness and principled counsel: Vibhīṣaṇa speaks plainly, valuing dharma over factional loyalty.
