In Book 3 of Jalaluddin Rumi's Masnavi, following his decision to counter Moses, Pharaoh dispatches messengers across Egypt to gather the most renowned magicians. The narrative highlights two famous young sorcerers whose worldly illusions were unparalleled—capable of milking the moon or selling moonlight woven as linen. When Pharaoh's message arrives, detailing how two humble dervishes equipped with only a single staff have rendered the Egyptian army helpless, the magicians experience an unexpected spiritual reaction. Rather than reacting with immediate hubris, a sense of 'fear and affection' penetrates their hearts. Stirred by a deeper spiritual affinity, they place their heads on their knees in profound contemplation. Rumi observes that for the Sufi, the knee serves as a 'schoolhouse' for solving mystical difficulties, foreshadowing the sorcerers' impending transition from purveyors of worldly deception to genuine seekers of divine truth.
