In this Sufi chamber, that poverty/simplicity is no longer present, the proof of which is the blood of the poet's heart.

This profound couplet speaks to the evolution of spiritual and artistic struggle. Allama Iqbal suggests that the visible, external poverty (faqr) once celebrated in Sufi circles is no longer enough. Instead, the true evidence of spiritual depth and struggle now resides in the deepest part of the poet's heart—the sacrifice, the pain, and the bleeding essence of his art. It's a shift from mere display to profound, internal suffering.
