अयोध्याकाण्डे एकविंशः सर्गः — Lakṣmaṇa’s militant counsel and Rāma’s dharma-based persuasion of Kausalyā
प्रसादयन्नरवृषभ स्समातरं पराक्रमाज्जिगमिषुरेव दण्डकान्।अथानुजं भृशमनुशास्य दर्शनंचकार तां हृदि जननीं प्रदक्षिणम्।।2.21.63।।
tasmin punar jīvati dharmarāje viśeṣatas sve pathi vartamāne | devī mayā sārdham ito 'pagacchet kathaṁ svid anyā vidhaveva nārī || 2.21.60 ||
While that king of righteousness yet lives—especially while he abides upon his own path of dharma—how could the Queen depart from here with me, like some other woman, as though a widow?
Rama, the best among men, thus pacified his mother insisting on his desire to depart for Dandaka forest with courage. And elaborately instructed his brother about his good intentions after which he circumambulated his mother with all his heart.ityārṣē śrīmadrāmāyaṇē vālmīkīya ādikāvyē ayōdhyākāṇḍē ēkaviṅśassargaḥ৷৷Thus ends the twentyfirst sarga of Ayodhyakanda of the holy Ramayana, the first epic composed by sage Valmiki.
Dharma is framed as maintaining proper familial and social order: a wife should not be treated as widowed while her husband lives, and a son should not disrupt that order.
Rāma discourages Kauśalyā from accompanying him into exile, arguing it would be improper while Daśaratha is still alive and righteous.
Rāma’s sensitivity to maryādā (propriety) and his protective concern for his mother’s dignity and social standing.
