In Chapter 23, Poem 10 of Attar's Mokhtar Nameh, the poet reflects on the rapid, unnoticed passing of life, which slips away 'like the wind.' The poem draws a stark contrast between the 'day of youth' and the impending 'night of death.' A crucial conceptual focus is the intense dread of the 'first night' (شب نخست) – a reference to the first night in the grave in Islamic eschatology, traditionally considered a frightening time of questioning and reckoning. The imagery of the heart turning to blood underscores the profound anxiety and sorrow confronting the mortal soul as it faces the immediate, solitary reality of death.
