In Chapter 43, Poem 11 of Attar's Mokhtar Nameh, the poet employs the classic metaphor of the 'intoxicated nightingale' (بلبل مست) to illustrate a soul lamenting out of the profound grief of divine love. The poem portrays an internal burning (سوز دل) so intense that the speaker fears it could consume the 'nine veils of heaven.' This imagery conveys the overwhelming, all-consuming power of mystical longing and the isolating nature of a spiritual sorrow that remains unknown to the outside world.
