In this poem from Attar's Mokhtar Nameh, the concept of a 'living heart' (zendeh-deli) is presented as the essential requirement for spiritual awakening. The poem suggests that to resolve deep mystical difficulties and to comprehend a sage who transcends both the material and spiritual domains ('the two worlds'), a seeker must have gained profound experience ('a harvest from a long life') and possess inner spiritual vitality. It contrasts this awakened state with the 'dead-hearted,' emphasizing that transcendent wisdom can only be accessed through an active, living spiritual heart.
