In Poem 67 of Mokhtar Nameh, Attar discusses the concept of absolute Divine Unity (Tawhid) and redefines polytheism (Shirk) in a mystical context. He asserts that since existence is fundamentally One, focusing on the self or perceiving any 'other' besides the Divine constitutes a form of hidden polytheism. The spiritual traveler is urged to look beyond physical dimensions and dualities to realize that acknowledging duality in a unified existence contradicts the true essence of Tawhid.
