In Chapter 31, Poem 38 of Attar's Mokhtar Nameh, the poet explores the themes of spiritual veils (حجاب) and the hidden nature of the Beloved. The path is described as being obstructed by superficial religious identities and formalistic dogmas, symbolized by both the Sufi cloak (خرقه) and the non-Muslim belt (زنار). Because the world is crowded with these 'strangers' (اغیار) and illusory barriers, the divine truth remains concealed from sight. Consequently, the true seeker is called to endure profound spiritual suffering, metaphorically described as 'drinking blood' (خون خوردن), in order to persist through these pervasive veils.
