In Chapter 32, Poem 11 of Attar's Mokhtar Nameh, the poet explores the paradox between 'lawful blood' (خون حلال) and 'consuming the forbidden' (حرام‌خوار). In Islamic jurisprudence, consuming blood is strictly forbidden (haram). However, within the Sufi literary tradition, 'drinking blood' (خون خوردن) is a prevalent metaphor for enduring deep spiritual sorrow, hardship, and the agonies of love. Attar suggests that for a true spiritual seeker, this inner suffering is not only lawful but necessary. The poem criticizes those who succumb to worldly sins and literal forbidden consumption, emphasizing that true spiritual purification requires partaking in the metaphorical, 'lawful' blood of inner hardship.
