In Attar's 'The Tale of the Vizier Who Had a Beautiful Son' from the Elahi Nameh, a Sufi falls deeply in love but chooses to endure immense suffering rather than reveal his feelings. He keeps his love entirely hidden in his heart, ultimately weeping tears of blood until he goes blind. This narrative illustrates the Sufi concept of concealing the spiritual secret (ketman-e sirr) and silent endurance. It emphasizes that true mystical love requires internalizing the pain of separation and undergoing self-effacement, rather than seeking public relief or making a display of the soul's yearning.
