More than any other Persian poet—even Rumi—Hafiz expanded the mystical, healing dimensions of poetry. Because his poems were often ecstatic love songs from God to his beloved world, many have called Hafiz the “Invisible Tongue.” Indeed, Daniel Ladinsky has said that his work with Hafiz is an attempt to do the impossible: to render Light into words—to make the Luminous Resonance of God tangible to our finite senses.
