In Poem 98 from Chapter 4 of Attar's Mokhtar Nameh, the poet explores the theme of spiritual annihilation (fana). The heart, weary of temporal existence, becomes annihilated and transcends the dualities of good and evil. By immersing itself completely in the contemplation of the Divine, the heart is emptied of all 'other' thoughts, leaving room only for the Beloved. This illustrates the mystical concept of exclusive devotion and the erasure of the self in the presence of the Divine.
