In Farid al-Din Attar's Conference of the Birds, the tale of the merchant who builds a golden mansion serves as a sharp critique of material vanity and ego. The merchant, driven by pride, constructs a lavish home and invites the public simply to show it off. The narrative introduces a 'diwana' (a mystic madman or holy fool) who shatters this illusion of grandeur with a crude and shocking threat to defile the mansion. Through this stark contrast, Attar highlights the Sufi perspective on the worthlessness of ostentatious worldly wealth. The madman acts as a spiritual mirror, exposing the absurdity of the merchant's attachment to transient material achievements and his spiritual immaturity.
