If Suhni had not (taken the risk and) entered the river, how could she have achieved publicity? She would have passed her span of life in obscurity. A sip of milk, which Mehar gave her, ecstasised her. Sayed says: "She did sacrifice herself on the alter of love. Normally too she would have died, but due to her drowning in the course of love, she earned two fold recompense" (i.e. good name here plus Allah's pleasure in the Here after).
And if you are slain in the cause of Allah or you die, surely forgiveness from Allah and (His) mercy shall be better than what they hoard.
(157, AI-Imran).
قارون ہلاک شد کہ چہل کانہ گنج داشت
نوشیرواں نمرد کہ نام نکو گذاشت
(Saadi)
Qarun who had forty treasure houses, was destroyed (and effaced). Nousherwan did not 'die' and sink into oblivision, as he left behind a good name.

Who would have heard of Suhni, had she not the waters entered?
How long would she have been on this earth?
That draught crazed her which he milked,
Love killed Suhni, so says Sayed,
She would have died any way, drowning, her wroth doubled.

Had she not entered the river, no one would have heard of her,
She would have passed her life as if she did not exist.
The sip of whey that Mehar gave her to drink enthralled her,
Sayyad says, love practically killed Sohni,
She would have died any way,
But death by drowning doublet her worth.
