In Chapter 4, Poem 28 of Attar's Mokhtar Nameh, the poet explores the theme of spiritual readiness through the metaphor of the Divine Ocean. He contrasts a soul utterly captivated by the Divine with a 'sleeping heart' (دل خفته). The poem suggests that if the overwhelming reality of the Divine Ocean enters an unawakened or unprepared heart, it paradoxically destroys the individual with an agonizing, unquenchable thirst, emphasizing that spiritual capacity is required to endure the Divine Presence.
