This concept from Poem 20 in Chapter 25 of Attar's Mokhtar Nameh explores the theme of mortality and the cyclical nature of life. Attar uses the imagery of spring clouds washing the dust of the dead to bring forth new greenery, symbolizing physical regeneration from the earth. Furthermore, he suggests that even in death, the silent 'sleeper' remains expressive, as the very dust they have become eloquently speaks of the transient nature of human existence.
