मन्थराप्रवेशः — Manthara Observes Ayodhya and Incites Kaikeyi
उपस्थितः प्रयुञ्जानस्त्वयि सान्त्वमनर्थकम्।अर्थेनैवाद्य ते भर्ता कौसल्यां योजयिष्यति।।।।
upasthitaḥ prayuñjānas tvayi sāntvam anarthakam | arthenaivādya te bhartā kausalyāṃ yojayiṣyati ||
Though he comes to you and offers only futile words of consolation, today your husband will grant the true advantage to Kausalyā alone.
When your husband approaches you he swears in meaningless, appeasing words. But today he is going to bestow benefit on Kausalya only.
It contrasts empty speech with meaningful action; dharma values truthful intent and fair conduct over mere soothing words.
Mantharā claims Kaikeyī is being placated while Kausalyā receives the true benefit through Rāma’s elevation.
Justice/fairness is the implied standard—used here as a grievance to provoke Kaikeyī.
