Who has flown the sword of love from the heart? Empty is the measure in the hands of knowledge, O cupbearer.

This profound couplet by Allama Iqbal draws a stark contrast between the intensity of passionate love (Ishq) and the theoretical nature of knowledge (Ilm). The poet questions who could possibly remove the 'sword of love' drawn from the very core of the heart. He then addresses the 'Saqi' (cupbearer), observing that even the hand of knowledge remains empty. It suggests that mere academic or intellectual pursuit, while valuable, cannot fill the deep, existential void created by profound emotional experience.
