In Chapter 6, Poem 12 of the Mokhtar Nameh, Attar describes the ultimate mystical state of annihilation (fana) that occurs when the heart plunges into the depths of the divine ocean. The seeker becomes so overwhelmed by the spiritual magnitude of this journey that all worldly faculties cease to function. The 'mute tongue' represents the sheer ineffability of the divine experience—where words completely fail to capture the truth. Concurrently, the 'lost heart' symbolizes the complete dissolution of the individual self into the vastness of God, shifting from possessing a worldly identity to utter obliteration in the divine presence.
