सुमन्त्रस्य कैकेयी-निन्दा (Sumantra’s Reproof of Kaikeyi in the Royal Assembly)
अभिजात्यं हि ते मन्ये यथा मातुस्तथैव च।न हि निम्बात्स्रवेत् क्षैद्रं लोके निगदितं वचः।।2.35.17।।
āmraṃ chitvā kuṭhāreṇa nimbaṃ paricarettu yaḥ |
yaś cainaṃ payasā siñcet naivāsya madhuro bhavet ||2.35.16||
If someone fells a mango tree with an axe and tends a neem in its place—even if he waters it with milk—it will never become sweet.
Your nature corresponds to your mother's, so I think. 'Honey will not flow from a nimba tree' is a well-known saying in this world.
Outer acts cannot transform inner nature without genuine moral reform; dharma is rooted in character (svabhāva), not in superficial displays or pampering.
Sumantra uses a sharp proverb to argue that Kaikeyi’s conduct reveals an ingrained disposition that cannot be ‘sweetened’ by external measures.
Discernment (viveka): Sumantra distinguishes between appearance and inherent moral quality.
