In Poem 42 from Chapter 44 of Attar's Mokhtar Nameh, the imagery of flowing water is used to illustrate the irreversible passage of time. The water's declaration that it has gone and will never return serves as a philosophical reminder of mortality. This emphasizes the theme of carpe diem, urging the listener to seize the present moment, abandon rigid repentance, and appreciate the fleeting beauty of life while it lasts.
