In Chapter 17, Poem 6 of Attar's Mokhtar Nameh, the poet addresses the restless heart, urging it to endure its intense spiritual suffering (metaphorically described as sitting within the veil of blood). This internal turmoil is juxtaposed with a cosmic vision: the realization that every single atom (zarreh) in existence is silently weeping. This imagery reflects the deep Sufi theme of universal sorrow, illustrating the hidden, silent grief shared by all of creation in its separation from the Divine.
