In Farid al-Din Attar's 'The Conference of the Birds', the tale of the man who leaves behind a box of gold serves as a powerful allegory for the spiritual dangers of material attachment. After death, the man appears in his son's dream transformed into a mouse obsessively guarding his hidden treasure. This metamorphosis illustrates how an insatiable love for wealth degrades the human soul, binding it to the earth and reducing it to a base, animalistic state. The parable functions as a didactic warning, emphasizing that hoarding earthly possessions obstructs spiritual liberation.
