मारीचस्य रावणं प्रति नीत्युपदेशः (Maricha’s Counsel on Kingship and Ruin to Ravana)
निवार्यमाणस्तु मया हितैषिणा न मृष्यसे वाक्यमिदं निशाचर।परेतकल्पा हि गतायुषो नरा हितं न गृह्णन्ति सुहृद्भिरीरितम्।।।।
nivāryamāṇas tu mayā hitaiṣiṇā na mṛṣyase vākyam idaṃ niśācara | paretakalpā hi gatāyuṣo narā hitaṃ na gṛhṇanti suhṛdbhir īritam ||
O night-roamer (Rāvaṇa), though I restrain you as one who seeks your welfare, you do not accept these words. For men whose life is spent—already as good as dead—do not take to heart the beneficial counsel spoken by friends.
O Ravana, you do not understand this word of warning coming from your well-wisher. Men who are going to die do not heed the advice given by their friends.ityārṣē śrīmadrāmāyaṇē vālmīkīya ādikāvyē araṇyakāṇḍē ēkacatvāriṅśassargaḥ৷৷Thus ends the fortyfirst sarga of Aranyakanda of the holy Ramayana the first epic composed by sage Valmiki.
Dharma here is the duty to heed हित (beneficial counsel) from a सुहृद् (true friend). Rejecting well-meant warning due to pride is portrayed as a sign of moral and spiritual decline leading toward destruction.
Mārīca warns Rāvaṇa against his reckless plan (the abduction of Sītā) and laments that Rāvaṇa, though advised by a well-wisher, refuses to accept restraint or correction.
The virtue emphasized is wise receptivity (listening to good counsel) and humility. By contrast, Rāvaṇa’s obstinate pride is framed as a mark of one moving toward inevitable death.
