In Chapter 8, Poem 17 of Attar's Mokhtar Nameh, the poet emphasizes the necessity of transcending one's ego to achieve intimacy with the Divine. The poem suggests that true devotion requires the absolute annihilation of the self (fana). Attar asserts that even if one commands both worldly and spiritual realms, maintaining any sense of self-existence or ego in the divine presence is considered spiritual infidelity (kufr). This highlights the core Sufi teaching that complete self-effacement is a fundamental prerequisite for divine union.
