In Book Four, Section 139 of the Masnavi, Rumi uses the narrative of the Prophet Muhammad requesting to see the Archangel Gabriel in his true, majestic form to illustrate the profound limitations of human physical senses. When Gabriel reveals himself—described as having seven hundred wings that obscure the sun and the entire horizon—the overwhelming spiritual reality proves too intense for the physical body to endure. Rumi utilizes this monumental encounter to contrast the frailty of the human physical form, which he compares to flint and iron, with the immense and concealed spiritual capacity within the human being, representing the divine spark or fire that transcends material weakness.
