In Attar's 'Tale of That Great One with Khwaja Ali Tusi' from the Elahi Nameh, the concept of spiritual pain (Dard) is presented as the essential catalyst for mystical transformation. The narrative asserts that a seeker must become entirely consumed by this spiritual agony to find the ultimate cure and achieve true spiritual maturity. Furthermore, the poem paradoxically equates this profound suffering with a form of ego-death that is necessary to attain true spiritual life, emphasizing that the most profound mystical pain remains an unacknowledged reality in both worlds.
