In this tale from Farid al-Din Attar's Asrar Nameh, a dervish visits a butcher after craving meat for a year, but is handed only bones and liver. The dervish accepts the liver, drawing a parallel to his own spiritual condition as a 'liver-eater' (jigar-khwar), a Persian literary idiom for one who suffers intense emotional anguish and grief. The allegory contrasts the initial worldly desire for material sustenance with the mystic's reality of consuming their own sorrow on the spiritual path, illustrating the ascetic's embrace of suffering, self-denial, and total absorption in the grief of divine love.
