2.9.28

kubje tvāṃ nābhijānāmi śreṣṭhāṃ śreṣṭhābhidhāyinīm
pṛthivyām asi kubjānām uttamā buddhiniścaye

She ceased. So counselled to her bane
Disguised beneath a show of gain,
Kaikeyí in her joy and pride
To Manthará again replied:
'Thy sense I envy, prudent maid;
With sagest lore thy lids persuade.
No hump-back maid in all the earth,
For wise resolve, can match thy worth.
Thou art alone with constant zeal
Devoted to thy lady's weal.
Dear girl, without thy faithful aid
I had not marked the plot he laid.
