The world of the mind involves burning passion, deep feeling, and desire; while the world of the body deals with worldly gain, deceit, and art.

This powerful couplet by Allama Iqbal draws a sharp contrast between two worlds: the inner world of the heart and the outer world of the body. The 'world of the heart' is defined by genuine passion (saz-o-masti) and deep longing. But the 'world of the body' is depicted as a place of transaction—a market of deals, trades, and artificial artifice. Iqbal suggests that true existence lies in the emotional depth, not the material exchange.
