In Chapter 16, Poem 15 of Attar's Mokhtar Nameh, the concept of 'manliness' (مردی - mardi), which signifies spiritual courage and fortitude in Sufism, is defined through unconventional metaphors. Attar associates it with being a 'rogue' (رند - rend) and a 'gambler' (مقامر - moghamer). In Islamic mysticism, a rend is a spiritually liberated individual who defies superficial social conventions and hypocritical piety, while a gambler is one willing to risk and lose their entire worldly ego for the Divine. The poem further outlines the qualities of this spiritual state: complete liberation from concerns of the 'beginning and the end' (creation and the afterlife), total congruence between the inner and outer self (sincerity), and maintaining the posture of a silent, patient observer.
