In Chapter 17, Poem 9 of Attar's Mokhtar Nameh, the poet addresses the "weary heart" (دل خسته), urging it to conceal its inner suffering and spiritual agitation ("Sit within your own veil and do not flaunt your blood"). The poem juxtaposes the individual's call to silent endurance with a profound vision of universal, cosmic sorrow, depicting every single atom in existence as weeping blood while remaining entirely silent. This reflects a core mystical teaching in Sufism: the spiritual seeker must internalize their profound grief and turmoil, recognizing that they participate in a vast, silent existential sorrow that permeates all of creation.
