In Chapter 33, Poem 16 of Attar's Mokhtar Nameh, the poet explores the paradoxical necessity of both divine concealment and spiritual pain. The poem uses the imagery of the moon hidden beneath a cloud to illustrate that the veiling of divine beauty is an act of mercy, without which humanity might be driven to destructive madness or rebellion ('raised a sword against You'). Furthermore, the poet asserts that the suffering ('pain') bestowed by the Divine is essential for the soul's progression; if God were to withhold this purifying pain, the heart would be condemned to a far worse state of eternal stagnation and regret.
