In Chapter 30, Poem 11 of Attar's Mokhtar Nameh, the poet explores the profound dichotomy between the self and the heart. The heart is depicted as being entirely consumed by its grief and yearning for the Divine, dragging the speaker into a harsh ordeal. Even though the speaker (representing the lower self or body) claims to be detached from the heart's specific sorrow, the intensity of the heart's spiritual yearning burns and ultimately 'kills' the self. This illustrates a central Sufi theme: the destructive, all-consuming power of divine love and the inevitable suffering it inflicts upon the lover's existence.
