अरण्यकाण्डे एकोनत्रिंशः सर्गः (Sarga 29: Rama’s Admonition to Khara and the Shattering of the Mace)
प्राकृतान्राक्षसान्हत्वा युद्धे दशरथात्मज।आत्मना कथमात्मानमप्रशस्यं प्रशंससि।।।।
prākṛtān rākṣasān hatvā yuddhe daśarathātmaja | ātmanā katham ātmānam apraśasyaṃ praśaṃsasi ||
O son of Daśaratha, having slain only ordinary rākṣasas in battle, why do you praise yourself—one not worthy of praise?
O son of Dasaratha, it is not praiseworthy to kill ordinary demons in war. Why do you praise yourself for it?
A social ethic of humility is invoked (even if hypocritically): true merit does not require self-praise.
Khara responds to Rama’s challenge by attempting to shame him for self-assertion before the duel continues.
Humility (amānitva) is named as a virtue—though spoken here by an antagonist as a taunt.
