From the Rumi list today:

Dear soul, Love alone cuts arguments short,
for it alone comes to the rescue when you cry for help against
disputes.
Eloquence is dumbfounded by Love: it dares not wrangle;
for the lover fears that, if he answers back,
the pearl of inner experience might fall out of his mouth.

Mathnawi V: 3240-3241
