This allegory in Attar's Mosibat Nameh presents a dialogue between an Imam and a mystic (bidel) regarding the nature of Divine Greatness (Kibriya). While the Imam asserts that God is absolutely pure and beyond the 'dust of humiliation' (gard-i mezallat), the mystic argues that the 'dust' of humanity and the material world is the very dust that sits upon the skirt of the Divine. The story illustrates the Sufi paradox that human nothingness and humility are the only means of proximity to God's absolute transcendence, concluding that all humanity exists in wait for the vision of the Divine.
