In Chapter 23, Poem 40 of Attar's Mokhtar Nameh, the poet reflects on the fleeting nature of youth and the physical signs of aging as a prelude to mortality. The poem uses the striking metaphor of 'camphor' appearing at the temples to symbolize the arrival of white hair. In Islamic burial practices, camphor is used to prepare the deceased, making this physical change a direct, sobering reminder to prepare one's burial shroud and spiritual state for the imminent arrival of death.
