In Chapter 20, Poem 20 of Mokhtar Nameh, Attar emphasizes the profound, transformative power of inner pain (درد). The poem suggests that a heart fully awakened by authentic suffering possesses such spiritual potency that even a lifelong coward sitting in its shadow can be transformed into a courageous person. This illustrates the idea that genuine spiritual pain is not merely an affliction, but a powerful catalyst for inner alchemy and strength on the Sufi path.
