In Attar's Mokhtar Nameh (Chapter 9, Poem 29), the metaphor of casting a single needle—representing the last remaining attachment to the 'two worlds'—into the sea highlights the theme of absolute renunciation. The seeker's state of profound bewilderment (heyrani) and perplexity drives them to abandon even this minor attachment to existence, illustrating that the path to divine proximity requires releasing all worldly ties.
