In Poem 15 of Chapter 6 in Attar's Mokhtar Nameh, the poet vividly illustrates the Sufi concept of Fana (annihilation of the self). By using the metaphor of galloping into the 'sea of annihilation' (دریای فنا) and casting oneself into its deepest depths, Attar describes the ultimate goal of the spiritual seeker. The poem emphasizes the finality and totality of this dissolution; once the seeker merges with the divine essence, their individual ego and identity are completely erased, meaning they can never be found again.
