In Attar's mystical poetry, the 'hair' (mūy) often serves as a metaphor for the most subtle and delicate veil of separation remaining between the lover and the Divine Beloved. When the lover asserts that no hair exists from their side, it signifies the complete annihilation of their ego and desires. The lingering separation—the single hair that remains—is depicted as being maintained entirely by the Beloved. This highlights the philosophical concept that ultimate union (wasl) is dependent upon divine grace and will, rather than solely on the lover's readiness.
