In Chapter 17, Poem 12 of Attar's Mokhtar Nameh, the poet expresses a profound desire for ultimate self-effacement and spiritual silence. The metaphor of wishing for the secrets of the heart to become a nail upon the tongue illustrates the immense burden of inner mystical experiences, which must remain hidden from the outside world. The poem underscores the isolation of the mystic whose deep inward grief cannot be articulated or fully comprehended by others.
