Valmiki Ramayana · Ayodhya Kanda · Sarga 7
अनिष्टे सुभगाकारे सौभाग्येन विकत्थसे। चलं हि तव सौभाग्यं नद्यास्स्रोत इवोष्णगे
aniṣṭe subhagākāre saubhāgyena vikatthase| calaṃ hi tava saubhāgyaṃ nadyāssrota ivoṣṇage
Though you appear to be your husband's darling, in reality he dislikes you. The good fortune you boast of indeed is unstable like the stream of a river in summer.
— M.N. Dutt (1891)
Commentary
'Your husband dislikes you; your good fortune is unstable.' Manthara's poison enters through the wound of loyalty — she claims to be Kaikeyi's only true friend, the only one who will speak the truth. This is the classic posture of the manipulator: I alone am honest with you.
