In Poem 43 from Chapter 4 of Attar's Mokhtar Nameh, the poet explores the Sufi concept of Fana (annihilation) by emphasizing the complete dissolution of physical and egoic distinctions in the spiritual realm (عالم جان). Attar argues that gender (man and woman), the dualism of body and spirit, and the subjective pronouns of individual identity ('I' and 'we') all lose their meaning upon reaching true spiritual unification. The poem admonishes those who cling to their dualistic ego, asserting that authentic spiritual existence transcends any notion of personal, separate identity.
