मारीचोपदेशः — Maricha’s Counsel to Ravana (On Rama’s Dharma and the Peril of Abduction)
शरार्चिषमाधृष्यं चापखङ्गेन्धनं रणे।रामाग्निं सहसा दीप्तं न प्रवेष्टुं त्वमर्हसि।।।।
kathaṃ tvaṃ tasya vaidehīṃ rakṣitāṃ svena tejasā | icchasi prasabhaṃ hartuṃ prabhām iva vivasvataḥ ||
How can you wish to seize Vaidehī by force, when she is protected by Rāma’s own splendor and power? Can anyone separate the sun’s radiance from the Sun himself?
You should not enter into the unquenchable fire that is Rama, the fire that has the arrows (of Rama) as its flames and his sword and bow as fuel.
Adharma—abduction and coercion—cannot succeed against dharmic protection; the righteous are safeguarded by the moral and martial power (tejas) of the protector.
Mārīca warns Rāvaṇa against abducting Sītā, arguing it is as impossible as separating sunlight from the Sun.
Rāma’s tejas (righteous might) and Sītā’s inviolability as a protected, lawful wife.
