In Poem 29 of Chapter 11 in Attar's Mokhtar Nameh, the poet describes a profound, 'liver-burning' spiritual pain that causes endless wandering and restlessness. This agony of the heart is accompanied by a sense of walking in darkness for a lifetime, seeking the 'Fountain of Khidr'—a mythical symbol of eternal life, esoteric knowledge, and divine guidance. The poem captures the mystic's desperate, agonizing pursuit of enlightenment and the profound sense of bewilderment when the ultimate truth remains elusive.
