In Chapter 29, Poem 5 of Attar's Mokhtar Nameh, the heart is depicted as a profound paradox: physically as small and helpless as a single drop of blood, yet spiritually vast enough to contain a hundred worlds of love and a thousand afflictions. This metaphor illustrates the immense capacity of the human heart and soul to endure spiritual affliction, serving as a microcosm where boundless divine love and overwhelming inner turmoil converge.
