“لطف” in the Masnavi

Had he (the king) not seen his (the goldsmith's) benefit in his severity, how should that absolute Mercy have sought to act with severity?

For instance, a child trembles in fear at the practitioner's needle, while the loving mother feels happy and relieved (knowing it is for her child's own good and well-being).

He takes away a meagre half-life and bestows a hundred lives in return; he grants you what your imagination could never even conceive.
