In Chapter 39, Poem 7 of Attar's Mokhtar Nameh, the poet employs conventional Persian physical metaphors to describe the beloved. The 'black down' (خط سیه رنگ) refers to the fine facial hair that enhances the beloved's beauty, while the 'slender waist' (میان باریک) is highlighted by the imagery of a garment becoming tight. These metaphors serve to illustrate the idealized and overwhelming physical attractiveness of the beloved in Persian lyric poetry.
