Valmiki Ramayana · Ayodhya Kanda · Sarga 7
तव दुःखेन कैकेयि मम दुःखं महद्भवेत्। त्वद्वृद्धौ मम वृद्धिश्च भवेदत्र न संशयः
tava duḥkhena kaikeyi mama duḥkhaṃ mahadbhavet| tvadvṛddhau mama vṛddhiśca bhavedatra na saṃśayaḥ
O Kaikeyi, your sorrow will augment my sorrow. Your prosperity would mean my prosperity. There is no doubt about this.
— M.N. Dutt (1891)
Commentary
'Your sorrow is my sorrow; your prosperity is mine.' Manthara's declared solidarity is the hook. She has merged her identity with Kaikeyi's interest. To reject Manthara's words is now to reject her own wellbeing.
