In Chapter 22, Poem 33 of Attar's Mokhtar Nameh, the transient nature of human existence is highlighted through the inevitable separation of the body and the soul. Attar uses this existential reality to deliver a moral directive: because death will ultimately silence the tongue from speaking of both good and evil, individuals should utilize their fleeting capacity for speech to employ a 'tongue of kindness' (زبان لطف) toward all creation.
